Title: GTD acceleration responsiveness
Post by: adekil on 03 May 2014, 20:05
Warning, this may not be explained too well!

As much as I love my GTD, from the beginning I expected more from the performance and have posted about this.

Over the last several months when the car is lagging with acceleration, out of curiosity I tested some things and noticed that when I switch modes after the car is running, the car reacts much more livelier as I would expect it to when setting off in the first place....

For example... I start the engine/journey in Sport mode and most times the car accelerates like a standard midrange TDI when pressing hard and revving high, but if I switch mode to Normal (no difference in response experienced), then back to Sport the car reacts amazingly quickly. This can sometimes happen switching from Sport to Normal, whereas Normal feels quicker.

Then if I was to stop the car and switch off the engine for a while, the performance when started again is as like above, I need to switch modes to get the most out of it.

Has anyone else noticed similarities to this and if so is it something a VW garage would pick up on if I was to book in?

Are you sure it's not just the car warming up? The GTD seems to have a protection system on it that limits output when cold. Never had this on any previous TDI . It would a right pain to have to select sport from normal every time you wanted to be a bit sporty. On the other hand though, my car is always in sport and I swear that switching to normal causes the car to have more low end response and it's 10% thirstier.

This is noticeable when cold and warm, I've even had other people take it out and they notice the same that when starting in Sport the car doesn't perform as expected, switch to normal or any other mode then back to Sport and the car is noticeably more responsive.

Quite often I notice too when switching from Sport to Normal the car again feels more responsive but only when the car is warmed up, I don't notice any difference when cold.

I know next to nothing about car mechanics or the software but it does appear switching modes once the car engine is on is triggering something but feel if I took this to VW I would be wasting a trip.

Most of the dealership techs know very little about the workings of the car beyond what the manuals and bulletins tell them when the car has been diagnosed by a computer. They get to work like someone picking a Lego kit to build and following the instructions precisely to get to the end product. They are rarely allowed to use their initiative, they remove and replace whatever the diagnostic equipment tells them to, or reinstall controlling software.

If the computer doesn't detect a fault or have one stored, as far as they're concerned, there is no fault.

It might well be worth trying having the car in normal to start on every journey and then flick it over to Sport, for a few days at least. If starting in Sport is treated by the car like starting in normal and only a change to normal (and possibly back to sport) mid journey initiates the true sport mode response then i'd consider it a fundamental fault. Doubt VW techs could confirm whether this is the case, and if it is, then VW should just have the car default to normal on start-up for every journey.

It might be a bit difficult to tell for me with the box on.

Post by: monkeyhanger on 04 May 2014, 13:22
Anyone with a GTI noticed same, with the modes in sport at the start and then a change to normal (and possibly back to sport)  resulting in better throttle response?
Title: Re: GTD acceleration responsiveness
Post by: monkeyhanger on 04 May 2014, 16:48
Well I had a play with this on a 3 stage round trip to pick my missus up from work, and it seems that no matter what mode the car was left in, it benefits from a change every journey. I have my individual set up for Sport on every setting except aircon, which is set to eco.

Drove to the missus' work. About 1/2 a mile into the journey I press the mode button and change from individual to sport and the car's low end pick-up improves and the car seems just a little thirstier than normal. Get to her place, engine off, play about on my phone for 10 mins until she comes out. Drive to Sainsburys (it's about 1/3 of the way home/3 miles). The car's low end pick-up isn't quite as sharp as it was when I changed modes. Change modes again, from sport to individual, and the car sharpens up again. Do the same from Sainsburys to home (6 miles), changing back from individual to sport again and the absent low end sharpness returns. Very weird.

Without changing modes, the car is plenty sharp for me with the DTUK box, but it's still noticeable. It's like the car defaults to Normal on every journey, but the display icons in the mode selection don't reflect that.
Title: Re: GTD acceleration responsiveness
Post by: adekil on 04 May 2014, 18:10
monkeyhanger, that's exactly what I experience and tried down to a tee for me to post this in the first place as it seemed not normal.

But as we've both noticed, switching to Normal is sometimes more responsive after setting off, so maybe the default is not Normal mode either than the one displayed?

Is this a flaw, design or a bug perhaps and is it worth booking in to a garage?

Strange that no one else has complained about this and instead raved about leaving the car in Sport mode as its so good!
Title: Re: GTD acceleration responsiveness
Post by: dippy_x on 04 May 2014, 18:40
Could it be defaulting to Eco mode?  That is the only other option available.  My GTD stays in individual setup with engine set to normal.  This is the one feature of the car I haven't really played about with.  Sounds like a nightmare to try and explain and demonstrate to the dealers / VW.
Title: Re: GTD acceleration responsiveness
Post by: monkeyhanger on 04 May 2014, 18:50
Yes, it does sound like a nightmare. It'll be a "leave it with us for a few days" scenario. 2 days later some scrote has put 100 miles on your car and thrashed it, leaving you with 1/3 of a tank gone. They'll say they couldn't find anything.

It's definitely no-where near as limp as eco mode, the pedal is decidedly dead in eco mode. It seems to me that the car always starts in normal mode (regardless of what the displayed mode says, if you haven't selected eco), and switching to anything but eco once the journey is underway results in a performance improvement. When I switch between normal and sport, the soundaktor behaves as it should e.g barely on in selected normal and louder in sport.

A few other people mentioned the same when I said ages ago that sometimes my normal seems more potent than sport. Might be harder to spot on a DSG (if it even happens with a DSG) because of the car deciding when it's going to change.
Title: Re: GTD acceleration responsiveness
Post by: adekil on 04 May 2014, 19:05
I have DCC too as an extra so chuck in Comfort mode as well but when I do start of in Sport, the steering is tight so must be Sport mode, and the soundaktor is noticeable too, so would it be just the engine mode defaulting to something else?
Title: Re: GTD acceleration responsiveness
Post by: dippy_x on 04 May 2014, 20:23
I thought the soundaktor depended on the engine mode?  If this is true then this further complicates things!
Title: Re: GTD acceleration responsiveness
Post by: mcmaddy on 04 May 2014, 20:41
Doesn't happen in my gtd but I think monkey is right in that when the engine is cold it's got some sort of limiter on it until the water temp has moved and maybe even the oil too.
Title: Re: GTD acceleration responsiveness
Post by: monkeyhanger on 04 May 2014, 21:37
I thought the soundaktor depended on the engine mode?  If this is true then this further complicates things!

It does. When my car is set to sport or the individual engine mode is set to sport, the soundaktor is performing as expected, the steering is acting as per sport. Flitting modes after start-up is definitely changing the low end characteristics of the engine, as if my car is always driving as per the normal setting without me changing it. Have been out again this evening. The car pulls hard from 1700 rpm after changing modes rather than from 2100rpm if I leave it alone. The DTUK box negates the difference, but as it's essentially amplifying the car's normal throttle responses, the difference can still be felt.

Glad it's not just me, it sometimes does seem like some weird ECU glitch, mcmaddy's car was built just 3 weeks after mine and his behaves normally. The cold limiter is something completely different again as I can get that and the mode switch changes too. The cold protection seems to be in place until the water hits 90 or the oil hits 50 (hard to tell as the 2 temp events happen about the same time when it is not freezing.

A weird thing also happened later today, the fans came on when I parked up, they were blaring (as usual when the DPF is trying to cool) until I turned the engine off, then they settled down to a fan speed about 1/3 blaring speed. Never had variable non-ignition fan speeds before, the car has either been blaring or they've not been on at all. I'll mention the modes thing when I take my car for it's first service. I'm at about 7300 miles now, so it'll be due end July/start Aug.
Title: Re: GTD acceleration responsiveness
Post by: Skinnee D on 05 May 2014, 08:28
Just recently I've been thinking I could detect a bit of variability in response and wondered if it could be down to fuel. I'll try mode switching as you have and post back what happens. Agree 100% with MH on the outcome if given to a dealer to investigate. Hopefully a software update at servicing might sort it?
Title: Re: GTD acceleration responsiveness
Post by: monkeyhanger on 05 May 2014, 09:34
What I find really weird about this issue is that the car has found a way to separate throttle response from soundaktor function within the "engine" setting on the modes.
Title: Re: GTD acceleration responsiveness
Post by: mcmaddy on 05 May 2014, 10:20
Just out of interest the manual states you can only change modes while standing still and not on the move. Maybe the mode ecu gets confused if you change whilst moving but it's a bit rubbish of you need to pull over every time you want to change mode. Still haven't had this issue on my car though and I change modes while driving.
Title: Re: GTD acceleration responsiveness
Post by: adekil on 05 May 2014, 11:27
Changing modes whilst driving works fine, the manual must be wrong or is advising rather than being a limitation; I only ever remember reading a warning in the manual that the drive style will change so don't flaw it

Plus if other GTD owners don't have the same issues as requiring to change out and in to Sport to activate it this must be a defect/bug mustn't it?

I certainly don't remember reading anything that the engine defaults away from sport each time the engine is switched off

I'd say this has to be a bug in the software rather than a flaw in an old software version if your car was made at the same time as mcmaddy's or later. mine was a BW 33, mcmaddy's was BW 36 (if I remember rightly) and i'm guessing yours will be BW 36/37 if you got yours 3 weeks after me.
I definitely feel/hear mode change come in when changing on the move.
Title: Re: GTD acceleration responsiveness
Post by: adekil on 05 May 2014, 19:02
Think I will get it booked in anyway on the off chance they have a software update or heard of this before (which I doubt) - At least after a day or 2 I will get the car back valeted. I'm not wagering £1 though on a fix.

I know changing modes while driving works OK but the manual states to do it before setting off. I wouldn't necessarily believe the manual either but it's down for all to see. Maybe VW can clarify if it's porkies or not?

I reckon this fan run on is because the aircon has been working harder, and the fans run on to dissipate heat from the aircon matrix. Remember this from my Mkiv days, as the fans used to blow their fuses in this mode.

Not tried the main thread adjustments, so I can't comment first hand, but sounds like a software error to me. I will try mine when I get the chance.

Post by: adekil on 07 May 2014, 09:25
My DPF comes on quite frequently but maybe that's down to my journeys usually being fairly short distances, don't know how it works in all honesty.

I had my fans blaring out once louder than normal but settled down shortly after the engine was switched off (5 - 10 seconds or so) not immediate but as its quite frequent I tend to be oblivious to it now.
Title: Re: GTD acceleration responsiveness
Post by: Skinnee D on 10 May 2014, 13:35
Having had a play this week, my belief so far is that if set to Sport the throttle defaults to Normal on starting (sound actuator still working), then flipping out of Sport and back again after the engine's warmed up sharpens up the throttle to Sport setting. 

I also reckon that stopping the car (warm engine) and restarting manually reverts the throttle back into Normal.

Sounds much the same as you guys I think - very puzzling. :huh:

Thanks for rubbing it in.  :grin:

Having tried multiple times now, my engine is definitely defaulting to normal engine response than sport (whilst retaining the sport soundaktor response expected in sport) until I change modes mid-journey. I will mention it during my service, when the DTUK box is off, because the difference is more pronounced and because I don't want them to see the box on.
Title: Re: GTD acceleration responsiveness
Post by: adekil on 11 May 2014, 17:51
Monkeyhanger, when are you planning to book your car in as if its soon I will hold off booking mine in specifically for this problem?

I am tempted to call VW anyway as my DPF regen kicks in at least a couple of times a week which doesn't seem normal, and when it does my wife always says she can smell burning when exiting the car.
Title: Re: GTD acceleration responsiveness
Post by: monkeyhanger on 11 May 2014, 20:28
Adekil: it'll be late July/early August in all likelihood. What's the daily commute like? You ideally need a good 6 miles a day beyond the time/distance it takes for the oil temp to get to at least 90C. Right now, 15 miles is ideal, although I get by on 12 miles each way because the car runs a little hotter with the DTUK box on (95C oil temp, like recent TDIs rather than 90C that the GTD seems to prefer*). 12 miles wasn't enough before the box. Failing that, 2 x 40 mile trips a week should keep the DPF nice and clean.

* due to minimising NOx for the Euro 6 emissions limits I suspect.
Title: Re: GTD acceleration responsiveness
Post by: adekil on 12 May 2014, 07:51
My daily commute is short, probably around 5 miles each way and recently not been doing many long journeys at the weekend.

I will bare those distances in mind and take some longer routes to see if this improves.
Title: Re: GTD acceleration responsiveness
Post by: monkeyhanger on 12 May 2014, 08:20
Left my car in "normal" mode, which is acting like "sport" is expected to, but without the soundaktor. Don't have to keep flitting modes to get the sporty response, unless i'm missing the soundaktor noise.

The biggest difference is the turbo assisted pick-up in power. In the normal (sport indicated on mine) mode the car seems to pick up strongly from 2100 revs, in sport (indicated normal on mine or after leaving sport and coming back to it), it picks up strongly from 1750 revs. The initial difference is noticeable, but above 2100 revs there is no difference between the 2 that I can discern. Me leaving it in "normal" (sport response for me) results in around a 5%/2mpg fuel penalty for me, but i'm enjoying the car so much with the DTUK box, I really don't care.

Adekil: When you leave yours in "normal" is it acting as you'd expect "normal" to, or does it seem a little livelier than "sport" without having to come out of sport and then back into it?

50mpg (indicated, likely 45/46 actual) on the way to work today with a heavy right foot.
Title: Re: GTD acceleration responsiveness
Post by: adekil on 12 May 2014, 12:06
I used Normal a lot over the last months and just recently and each time I start up the car in Normal (after leaving it in Normal) the responsiveness is just Normal, certainly not as lively as Sport (once the switching out and in is done)

There were times when I was driving in Sport (started in Sport) and when switching to Normal the car felt livelier - So for me starting in any Mode I don't seem to get the best out of that particular Mode without switching.... Although I only really use Sport, Normal & Individual (set to Sport in most)

With that said and Normal mode seemingly more responsive at times I'm still not convinced the engine is defaulting to Normal. So regardless of the car being warm or cold how can Normal mode give at least 2 different feels in responsiveness. I remember reading some reviews that the GTD Normal mode was just as good as Sport if not just slightly behind it, but in my opinion its quite far behind Sport until you perform the Mode switch.
Title: Re: GTD acceleration responsiveness
Post by: Gordor on 12 May 2014, 22:01
After reading this thread I thought I'd give it a go. Mine is set on individual, most on sports and there is a definite improvement when I switch the car into eco mode and then back again.
Title: Re: GTD acceleration responsiveness
Post by: KyleB on 14 May 2014, 16:24
I was intrigued reading this thread and tested this out for myself last night. Couldn't see a big improvement, but I'm going to keep investigating. Like Gordor my car is always in individual (everything sport apart from ECO air-con)

Anyone got any further findings?
Title: Re: GTD acceleration responsiveness
Post by: adekil on 14 May 2014, 17:07
KyleB, when did you receive your car? Mine was delivered 1st October, so perhaps this bug is isolated depending on when the car was built
Title: Re: GTD acceleration responsiveness
Post by: monkeyhanger on 14 May 2014, 17:21
The mode issue some of us are having doesn't seem to be restricted to build week. Adekil seems to have gotten his within a week of mcmaddy, who doesn't have the issues. I got mine 8th Sept, a BW33 car.

Any common denominator like lack of options etc? I have no options on mine. Just wondered whether there is a default ECU flash that gets modified when options are added, maybe the default/unmodified flash is buggy?
Title: Re: GTD acceleration responsiveness
Post by: adekil on 14 May 2014, 17:44
I can't see anything common here with options or anything else then if not build week.

Checked other forums too and nothing comes up.

Tomorrow will book the car in with VW and hopefully get a soonish slot and feedback anything or nothing!

You should be able to have the last laugh, they're only 3 cylinder (even the derv is 3!). Impressive figures but it's not about the max power it's all about the torque (and range) and a 2 litre derv will always pull away as the smaller capacity runs out of breath pretty quickly  :wink:

Title: Re: GTD acceleration responsiveness
Post by: adekil on 29 May 2014, 09:29
Car has just been collected and on the forms were marked recall for 45D4 which from what I've read is fixing various software bugs, I was never informed about this in advance and only know cuz I booked the car in, so for others out there, don't necessarily expect a call to recall your car but expect a software update when you next book in for service/repair.

Hopefully this fixes the Sport Mode issue
Title: Re: GTD acceleration responsiveness
Post by: monkeyhanger on 29 May 2014, 12:27
Adekil - you'll have to let us know if your car is more responsive when left in sport, rather than leaving it and coming back to it. Software fixes could just be the handbrake fixes.
Title: Re: GTD acceleration responsiveness
Post by: Mohsin on 29 May 2014, 13:30
Okay, I have been following this thread and I am confident mine is doing a similarly weird thing.

Before I read this I always used to leave it in Sport and did sometimes feel like it wasn't actually in Sport apart from the additional noise. Then after reading this I started testing by putting it back into Normal then to Sport. As you have mentioned, I can certainly feel the difference and it does feel like it is actually in Sport mode.

I don't know if it is just a placebo effect, that when we physically switch over to Sport mode within that same journey we are just believing it is responding a little quicker? Don't know, but even after deliberately starting off in Sport, doing the switch to Normal and back again, noticing the difference and then switching engine off, then start up again whilst still in Sport, I am positive there it feels like its back in Normal mode, until I do the switchy thing again.

Such a strange issue...really interested to see what VW say adekil.
Title: Re: GTD acceleration responsiveness
Post by: adekil on 29 May 2014, 15:55
VW have called back saying they cannot find anything wrong with the diagnostics, pretty much what I expected really.

I even asked if the guy who picked up the car tried the mode change and if he felt any difference, apparently he did and did not feel no difference

They have suggested I turn up one afternoon for a tech drive so I can demonstrate with an engineer and then determine whether it goes in again  :sad:

They have applied the software update though

Has any one had the same/similar issue that my 1.4 FR is suffering with at the mo?
When in Sport mode and the ignition is then turned off. On the restart to all intents I.e the mode switch is lit up and the screen says it is in Sport mode but the engine response defaults to normal, the door lights also default to white(normal mode) but the steering remains as it should for Sport mode. If I hit the the 'Sport' on the screen then it all works as it should. The mode function should retain the last setting it in it's memory according to the book.
My dealer is at the moment unable to effect a cure but Seat Technical are involved so hopefully it will be resolved soon.

Took a while but Seat have fixed my problem with the Mode retention. Apparently a combination of a software issue and one of the key fobs not compatible so both were recoded and all good so far.

Not sure how to approach getting this checked again and with another 2 years left on this car would be nice to know I'm getting the most out of it......

MonkeyHanger, did you mention this fault on your service?
Title: Re: GTD acceleration responsiveness
Post by: monkeyhanger on 13 October 2014, 19:43
Adekil: I did mention the mode fault and they said they'd take a look, time permitting (apparently the software updates to be applied during the service were goiing to take 2 hours, even though the service itself would only take 1). Car is ready after service (2 hours after it went in) and they supposedly didn't find any faults, but the car is cured. My car is running 10% thirstier post service, and the oil likes to be a little cooler - 90C rather than 94/95 when the car isn't being pushed.

Sport acts like Sport should now. Perhaps the extra thirst is because true Sport mode actually has an mpg penalty i've never experienced before by leaving it in Sport and actually getting Normal? Or maybe it's more to do with running a bit cooler?

Did the car fix itself inadvertently as a result of other software updates fixing a clash, or did they fix it and deny fixing it? I don't know, i'd like to think they wouldn't lie to me about something like that.

When in Sport mode and the ignition is then turned off. On the restart to all intents I.e the mode switch is lit up and the screen says it is in Sport mode but the engine response defaults to normal, the door lights also default to white(normal mode) but the steering remains as it should for Sport mode. If I hit the the 'Sport' on the screen then it all works as it should. The mode function should retain the last setting it in it's memory according to the book.
My dealer is at the moment unable to effect a cure but Seat Technical are involved so hopefully it will be resolved soon.

Took a while but Seat have fixed my problem with the Mode retention. Apparently a combination of a software issue and one of the key fobs not compatible so both were recoded and all good so far.

Guess it sounds like it's easier to 'diagnose' on the Seat because the door light color doesn't match up to the mode on the screen.  Maybe you need to show the VW garage the Seat thread.

I need to come up with the vcds cable matt before you trade yours in. Something I want to check and compare to mine.

Any time you like Chris. My dad never had this issue on his, you wanting to check that yours is the same as mine now it's fixed?
No it's something else  :wink:

Certainly when I had the software update, it made no difference as the car still felt more responsive when changing modes.

If the software update fixed the mode defaulting to normal then surely this must have been a known issue and documented somewhere and as my car was booked in specifically for this fault you would expect VW to check what was in the update and if it matched my symptoms.

You went wrong with "expect".  :grin: The dealership workshops are quite often useless - if there isn't a VWbulletin out for a fix and the car is driveable, they'll usually leave well alone.

I know :sad: When I have a few days off work will book in again so they can keep the car longer and use the missus car instead of an UP, not practical with 2 kids

My GTD had its first service yesterday. I was told verbally that they were going to update the software. When I collected the car I noticed that all my radio stations were still there. I took a photo of the software version screen and low and behold it was the same version as before. There was nothing written down on the job sheet that there was a software update planned.

I have the same problem as the rest of you do with sport mode not really feeling like sport mode. I normally change to normal, then to sport, to feel the change.

Could someone who has had their GTD updated to the latest software possibly post  it, so I can take a look. The car has to go in again for some minor warranty work, so if I can get them to update then, that would be the plan  :smiley:

Sam, without checking first myself, where do you go to see the software version?

I will check in a bit and post back here

OK checked, and i'm on software version 0421

Monkeyhanger, whats your software version as you're the only person who has reported having the issue whereas its now resolved - perhaps the version number doesn't change if the update was purely bug fixes...

Don't think mine change anything on the headunit version screen, but I do have a small campaign sticker put in the boot under the carpet next to the spare wheel. I'll see what it says and perhaps take a snap ?

A software update for engine management won't show up on the head unit, that's just for media software. The sticker in the boot will be the 4d4 whatever it is update. They hook the car up to the computer and if anything needs updating it updates as part of the service. Should be noted on paperwork though.

also, depending on when you got your car you may or may not need the update.  Mine was serviced in Sept and there were np updates required.

I spoke to the service guy about the software being the same version as before. He said that my car had received a brake electronics software update and that it wouldn't show up on the head unit. The version on the head unit in the 'System Information' section is 0192 and Hardware version H40.

I must look in the boot for the other sticker.

Mine went for its first service last week.  They installed their "engine management" software update (45d4?), and checked the original head unit / driver profile software version (Sept 13 car) but reckoned it was up to date.  So far it still seems to be resetting the throttle from sport to normal on a manual engine start.  I did mention that problem specifically to them beforehand but they didn't seem to have any knowledge of it...  Oh well :huh:

Mine does this too, annoying. Has anyone had any further updates on it?

Mine got fixed following my first service in August, even though they denied fixing anything (i'd brought up the mode reset issue prior to the service) - I assumed any software updates inadvertently fixed it rather than a successful attempt to fix the issue raised.

Just joined,

Took delivery of my 5dr GTD Manual in December. I seem to have this bug too. Have to cycle through modes every time I start to get the sporty feel I want.

Colleague also took delivery of one the same day but he is not seeing this problem. My VIN number is slightly later than his but we have the same spec options etc.

Spoke to the dealer but they haven't heard of this. Suggested I book it in for a tech to try and diagnose before they contact the factory. But My experience of this is that will not find the issue themselves and give me a blank look as if to say I'm imagining it. Can't be doing with the inconvenience to not get a solution.

Hoping to be able to give them more info as to what fixes it first.

I can't find this boot sticker? Can someone describe where it is?

My on dash display is version 0421

My service is 17,000 miles off and that will probably take me a couple of years.

All they'll do is reset the basic settings in the car which will probably fix the problem. At least let a dealer try before saying it was an inconvenience  :grin:

Its possible depending which garage you book your car into, what the mechanics actually try.

Took mine into Camberley twice and they had no idea nor made any effort to ask around.

I just live with it now as a 3 year lease with 1½ years left but if I owned the car I would be making more noise about it.

I will have to have more faith in the dealer and give them a try. I did today perform a factory reset via the setup menu but this hasn't helped.

How do you guys know the build week and such info? And as I only took delivery in December 14 will my car already have the 45D4 update applied?

Cheers
