I want to say a hello to all my fellow forum members...
I picked up my new GTI a month ago - it's a standard white 5 door and I'm loving it, and have just past 900 miles.
But... the engine has started to cut out occasionally :sad: and I wonder if anyone has had similar symptoms?
This afternoon a VW technician called, checked it and he test drove it for 20 mins or so but unfortunately he couldn't find any fault codes or other problems. I then drove it with him there for another 30 minutes or so and it cut out twice. It's now in the local VW garage to be checked over. Thankfully it happened when he was there as it's difficult to prove to a garage that an intermittent fault exists.
In summary, it seems to happen intermittenty when the engine is fully warm (Water 90c, Oil over 105c) when I'm pulling to a stop, dipping the clutch and putting it into first gear to prepare to pull off again. At that point for a second or two the engine seems to shudder slightly, the rev counter moves about between approx 300 to 800RPM and then the engines stops, before automatically restarting (although occasionally I've had to restart it manually). This happens regardless of whether the stop/start is on or off
On the US site golfmk7.com there are 15 pages of messages from people with the same or very similar problems.
Does anyone have any thoughts about this?
Many thanks
-
Sounds like the stop start system is trying to cut in. Maybe a fault in the gearbox electronics where it's sending a faulty signal as if it's in neutral for a brief moment. 🤷♂️
-
As the OP mentions it happens with the stop start system disabled my thoughts are it's unlikely to be a gearbox position sensor as that signal should be disregarded when the stop start system is not active.
I've had stalling issues on older cars and it was the crankshaft rotation sensor sending an intermittent poor signal.
There seems to be a lot of comments on the US forum about transport mode still being enabled, whatever that does I've no idea.
Good luck.... I've just got a new 7.5GTI with 570 miles on it so reading this and the US site leaves me with a luke warm feeling
-
I thought it sounded like the coasting system.... But I don't have manual so don't know how it works on that but it happens in the DSG car when you are about to stop.
-
You don't get coasting on the manual only dsg.
@Grahamt if one of the sensors is faulty then regardless if SS is on or off it could still cause the issue. If transport mode was still active then you'd be limited in revs and speed etc. I wouldn't pay much attention to US sites.
-
A manual 7.5 will auto-stop if you knock it out of gear (fully out of gear, foot off of clutch!) in preparation to stop (which the Mk7 wouldn't)
But only if all of the usual pre-conditions for start stop are met - the first one being the start-stop is actually not disabled using the button (after each turn on!)

No need to be feeling down about your car on this issue, I'm not downplaying the OP's experience btw who I'm sure will get this resolved, I've been on this site and looking at others for a few years now and this is the first I've come across this particular problem. VW build millions of cars around the world, there's bound to be common faults occasionally. The GTI is a great car and overall extremely reliable, in my 4 years of ownership it's had one broken wheel bearing (likely pothole damage) and a rattle fixed. Most reliable car I've ever had so far. So don't worry, just enjoy the drive :smiley:
-
Many thanks for all your contributions... it's really appreciated.
The problem referred to on the US site seemingly relates only to MY19 which apparently has a completely different ECU.
In summary, auto-stop definitely was turned off - the engine cutoff isn't smooth as with the auto-stop, but instead a bit rough with the revs bouncing about for a second or two for cutting off and them immediately restarting.
The VW technician seemed quite surprised when I eventually got the problem to occur as he hadn't seen it before.
I'm guessing it'll be quite difficult to diagnose as no fault codes and its an intermittent problem.
Anyway, the hire car they've supplied has turned up today so I'll just wait to hear from the garage.

Hi ick2006,
will you keep the thread update please, I guess there a quite a few MY19 on this forum, me included, that are very interested in the outcome, although as you said trying to find intermittant faults can be difficult.
-
Unfortunately, as expected they couldn't replicate the fault so I've just come back from the garage with the car... :angry:
However, on reflection, the fault occurred during the Easter weekend when we had the unseasonably warm weather and the air-con was cooling the car so that may also be a factor - the temperature today when they did 20 miles in it to try to replicate the fault is only 11c.
If there is a link to warm weather and maybe the air-con then, given the current forecast, it could be a while before the fault occurs again.
I'll definitely keep thread updated with any progress.
-
Try eliminating the aircon....
Either turn the climate control off and see if you can make it do it.
Or turn it on, press the "max" button and see if that makes a difference.
It obviously draws energy from the engine, i wonder if the tickover is so low that with the aircon on it drags it right down and almost stalls?
-
I promised to keep you all updated with any progress...
Until the last week or so I haven't had a re-occurrence of the stalling. However, after a cool May and June in North Yorkshire, the weather has now warmed up over the last week or two and the problem has returned.
Fredgroves - Thanks for your suggestion - I've tried turning off the air-con but it still happened, also I've tried fuel from different garages - again unfortunately no difference.
One thing I have noticed is that it does seem to do it more often when facing up a hill.
On a positive note, I'm guessing it's not a widespread problem in the uk otherwise there may have been replies to my post!
Also, despite this occasional problem the car is great and I'm enjoying driving it.

Hi, new to the forum but not to Golfs having previously had a MKII and MK IV GTi and a MK7 R. My new manual GTi was delivered today with 300 miles on it. I’ve only driven it a further 23 miles and it has stalled 3 times, on each occasion with the clutch fully depressed whilst slowing but not coming to a stop. On one occasion it almost juddered to a stop and then restarted itself, on both others the engine stopped and then restarted without me having to manually start it.
Start/Stop was on the 1st and 3rd time but off the second. Think this sounds very similar to the OP’s issue. Hoping this fault goes away as I’ve really enjoyed driving it for the short time I’ve been in it. If it happens again I’ll book it in with a dealer and update this thread with any outcome.
-
I wonder if they have (post WLTP) backed the idle revs off to real low (which will effect CO2 emissions positively) and sometimes this causes a stall...
I suspect you haven't heard much of the problem because how many new (post WLTP) manual GTI owners will be on forums will there be? R's and GTD's are now DSG only and most people prefer a DSG GTI....

I doubt it's anything to do with idle revs. I have a post WLTP manual. Smooth as anything- never comes close to stalling.
Sounds like an intermittent fault with one of the sensors when it gets hot.
-
I've got a sneaking suspicion this is similar to what I've got going on with my 2019 in the thread "7.5 GTI PP - Unhappy at low speed?".
On top of what I've said on that thread, my better half has complained about it stalling for no apparent reason at low speed a few times - to be honest I've taken this with a pinch of salt until this weekend while doing a pretty long road trip. I should have known better, she like myself has happily driven manual Mk5, 6 & 7 GTI's without issue until the arrival of the 7.5.
Car came within a few rpm of stalling pulling into a junction - just enough momentum to prevent a proper stall (think kangaroo). Second time was in a busy car park, dawdling around a corner at low speed & it stalled so unobtrusively that I didn't notice until nothing happened on the throttle & I noticed a "start manually" or whatever message was on the dash.
On both occasions start / stop was off.
After reading your concerns, the more I think about this the more I think it's a p*** poor map that's down to WLTP.

I suspect that it is a low idle combined with a poor compensation to air-fuel mix caused by warmer temperature giving less dense air.
I'll eat my hat if this isn't post WLTP buggery with the ECU to game the figures... by any chance is a manual GTI just under a CO2 bracket by couple of g/km?
-
A quick google suggests this is a global issue and affecting many cars. It would also suggest that whilst it seems to be predominantly manuals, DSGs are not immune.

It's an issue that's most associated with the troublesome 1.5TSI engine.

I jumped from a DSG 2018 GTI 7.5 PP into a DSG 2019 post WLTP GTI PP
There is a definitely a difference in the map with engine / DSG box.
The new car does feel very very close to stalling when coming to a stop - this has nothing to do with stop start - that is always turned off.
Also when in sport mode and manual DSG, the car will change up automatically before redline, definitely different from the previous GTI
-
Gaming those WLTP figures....

Checked my V5.CO2 is 155, which isn’t close to a threshold.
I’ve been out in mine earlier with this thread in mind. I watched the rev counter each time I pulled up to stop in some fairly slow town traffic. It always very smoothly stops at 750, without any variation, even when I tried de-clutching from over 2500 rpm. It’s a hot day, I have AC on too.
I’m sure you’re right that there has been some gaming for wltp. The question then is why this problem affects some owners and not others? Mine has always been smooth and very easy to drive in slow town traffic.
If my car was stalling in the way that some are describing, i’d be asking VW to fix it- it has to be a fault?
-
Anyone who's got this problem maybe try something out of my curiosity.... if (on a safe piece of straight private road *ahem*) you are going along at say a steady 40mph and you just come off the throttle push the clutch in, does it stall then? If the idle revs were too low, it would get lumpy and stall.
From what I've read earlier across the internet, some people believe that the clutch is not fully disengaging, which combined with the road wheels being stopped stall it as certain as it would be if you had stopped in gear without the clutch depressed at all - which wouldn't happen in my 40mph test above.
Some are saying that its the hydraulic reservoir somehow and that by pumping the clutch pedal 8-9 times fully it fixes it not just for that day, but permanently.... maybe an airlock in the reservoir?
Just trying to think logically here!

What did the previous car do then? I have a 2018 GTI and it certainly will change up

Further to my ongoing stalling problem, I successfully rejected my car and was due to get a new Golf GTI DSG on a 69 plate this coming Monday. I'll go into more detail when I get the car about what has happened over the last month or two.
However, today I received a call from the garage saying that they couldn't currently register it, or indeed any other VW on a 69 plate, due to some problem caused by new WLTP/RDE regulations due to come into force on 1st September. Not surprisingly VW are trying to get this sorted ASAP.
Has anyone else who's expecting a car on a 69 plate heard from their garage about this?
-
With effect from 1 September 2019 national authorities shall prohibit the registration, sale or entry into service of new vehicles that do not comply with the requirements set out in Annex IX of the Directive 2007/46/EC as amended by Commission Regulation (EU) 2018/183
Basically WLTP part 2.... and VW caught wrong footed again by the sound of things.
-
RDE details here:
https://caremissionstestingfacts.eu/rde-real-driving-emissions-test/
All new cars sold after 1st September 2019 must also pass these tests, as well as WLTP.

Well done on getting a rejection for the car, most important thing is they've agreed to it so if the replacement takes a bit longer then it's free miles on the current one :cool:

Got exactly the same issue, told 2 days before collection I can’t collect my GTI. Bit gutted as I’ve been told it take as long as upto the 9th September for the block to be removed. Only positive is that I’ve been given a car to use until then and apparently VW are looking into some form of compensation for affected customers.

Another update on the now concluded saga of the on-going problem with my stalling GTI manual...
After rejecting my original Golf GTI manual (now over 5 months old) on 13/8/19 I picked up my new Golf GTI DSG on Friday afternoon. So despite a 4 day delay due to the WLTP/RDE problem, it's still only taken 3.5 weeks for the rejection to be accepted and to pickup the new one.
I'll summarise the main things below - apologies for the length - it's definitely a summary but I guess you may be interested in some of the details:
* Due to a cool spring and not using the car very much the stalling problem didn't re-occur again till early July and it was taken into the supplying dealer on 22/7. I've been supplied with a couple of loan cars since then.
* The dealer has been able to consistently replicate the problem even in cooler weather but only by driving it hard to get the engine temperature up. They also noticed an occasional problem with the gear shift indicator not showing the correct gear
* They found a sporadic Neutral position fault and swapped over the sensor but it didn't help
* The problem was escalated to VW by the dealer and after various tests of fuel, checks for remapping, trackers, etc VW asked for the engine speed sensor to be changed but it made no difference
* On 7/8 I escalated to VW directly including to one of their directors to ask for their responses to be quickened and I spoke to them the next day when they confirmed that they didn't know what the problem was but that they were confident the fault would be found, and could possibly send one of their engineers to check it or ship the car down to their own workshop
* Later on the 8/8 VW asked for the camshaft actuator to be changed which again made no difference
* On the 12/8 I was told VW had asked that the oil sump be removed and that "swarf or metal filings" had been found there and in the oil. VW then asked for the oil to be refilled and the car tested again, and if swarf was found again then the camshafts would have to be replaced
* It was at that point that I made an appointment to see the dealer Business Manager of the dealer and formally rejected the car as I didn't want a car that I had wanted to keep long term to have a potentially serious engine problem which could cause problems after the warranty ended
* Following a lot of really great work by the Business Manager, VW quickly accepted the rejection and then the dealer located a new DSG car that they had in stock. So in the end I paid the extra for the DSG but the car came with Santiago Wheels, Dynaudio and 90% tinted windows which, in effect, I didn't have to pay for so a great deal and some compensation for the hassle
* Despite the negative sentiment I've read about the attitude of VW when people have problems and the difficulty in getting them to accept rejections, I must say that VW have also been very helpful throughout.
I genuinely have nothing but praise for the dealer, JCT600 York, who not only gave me a great deal when I purchased the car but have done absolutely everything they could have done quickly and professionally throughout the whole saga and then for them to find me a replacement so quickly was great - I would most definitely recommend them.
-
How are you finding your new car? :smiley:
-
I agree about jct600. Bought mine from Bradford and had such a positive experience my old man bought a gti from their dealer in hull. And i know he would deffo recommend them as well. Glad it went so well. Ive been lucky enough to never have issues with any dealer. Maybe im just lucky :whistle: but bonus with getting extra on the car u didn't have to pay for :cool:
-
The car's great and I think I'm now a convert to DSG having always had manuals - it also seem a little faster than the manual I had - maybe a consequence of its engine problem... I'm impressed by the gearshifts which are extremely smooth and I haven't noticed any of the problems I sometimes read about with DSG.
The second loan car was an almost new GTD (very impressed with it) so I got used to the automatic gearbox before I got the new GTI.
I can certainly now comment on the questions I sometimes read about 19 inch wheels without DCC and also Dynaudio compared to the standard system...
I was a little concerned when I got the spec of the new car showing the 19 inch wheels as I had been so impressed by the ride on my previous Golf with the standard 18 inch Parker wheels. The ride and road noise on the bigger wheels (with Pirelli P zero tyres) is worse than the 18 inch ones but still in my opinion perfectly acceptable - I notice it more as a passenger than as a driver. Having said that, my other car is a BMW z4 e85 with runflats and the ride on that definitely isn't good! The wheels look great so overall I'm very happy with them.
Regarding the Dynaudio, it's early days yet (probably need more fiddly around with the settings) and I know speakers also need to be run in, but I'm not that impressed and if I'd paid for it then I'd be disappointed as doesn't seem that much better than the standard setup for how I use it (mainly radio on low volume). However, when louder it does sound better and more powerful. Also it's not that expensive compared to some of systems in high-end cars.
-
Its still very curious that they couldn't find the answer.
I'd have thought that with very computer driven drive mechanisms that the answer should be fairly obvious, but clearly not.
I am glad though that you've had a good effective response and that you are rollin' again.
As you had a GTD and a GTI in so many weeks, any thoughts on one vs the other?
