I have one of the new Golf GTi mk5's with DSG gearbox.
I have found that the slightest touch on the brake pedal causes the computer to cut off fuel and so you have no control over the accelerator for a moment or two.
Major places where problem occurs:
Starting on an incline
Brake before corner then for a moment you are left with no power to negotiate the bend.
Brake before island, once again left with no power when you want it.
I consider this to be a safety hazard, twice now I have been stalled across a main road waiting for power to come in with traffic bearing down on me.
VW say this is normal - I wish I had not bought the damn car.
One more thing, combined petrol consumption in literature is 35mpg but the best you can get is 26mpg.
Don't buy a Golf GTi mk5 DSG until this sorted.
-
I would agree with you mate, thats got to be a major safety issue.
-
Surely thats when you should just treat it like an automatic though ? Pressing the brake disengages the throttle on every golf turbo made in the last 5 years .. "safety issue" they call it.
How much of a lag are we talking here ? Half a second ? They may be able to solve it with a software update .. but if its the DSG clutches taking time to kick in.. there's not a lot they can do about that because its mechanical.

i'm just curious does your dsg's grills open (with holes)?
-
I am amazed to read that VW have been selling a car where the driver does not have full and instant control over it's braking and accelerating functions.
This morning I was joining a main road and got stranded in front of a coach that was reall moving and this so called super car just sat there in the middle of the road refusing me access to the accelerator - that is dangerous.
I have been back to my supplier who is going to get the car in to check it out but they say that after checking with VW this is normal.
I can only hope that one of the chipping companies will come up with some decent software.
Not sure what holes are being asked about on the DSG?

I have a DSG on order due next month.
It sounds to me like this is more than a software issue if you were stuck in the middle of the road, pedal to the floor, nothing happening! Have you taken it to the dealer and demonstrated the problem? Is the fuel/throttle system definitely ok?
Does this happen incidently in manual mode i.e. going up/down using the stick or when you are in automatic? If this is as serious as you say, why havent the reviews picked it up yet? It doesnt sound right at all.

the grills that under the head lights,on the manual gearbox has got 5 holes ,on the dsg its should have most open to cool the dsg gear box.

Hi Antman
Interesting - All the grill holes below my headlamps are blanked off!

Surely you did not expect to achieve 35mpg with this car. I was getting at best 250 miles to a tank and averaging about 22-23 mpg. I was driving the car hard and enjoying it. If you are worried about the fuel consumption then I think you are in the wrong car. I work abroad so am not driving it at the moment but when I was home I was putting in 35 quid of optimax almost every day for 2 weeks, admittedly I did do 2000 miles in it though. I would do a 100 mile round trip each day and this would use half a tank on its own.
I am planning on driving to Krakow in Poland in the near future, I will be driving via Warsaw to Krakow, spend a few days in Krakow and then drive down to Prague for a few days then drive home. Total mileage for the journey is approx 2400 miles without any sightseeing trips in between and a fair bit of it will be at autobahn speeds. Will let you know what mpg i get but if I average 25mpg over the whole journey I will be well chuffed and if I get it down below 20 I shall also be well chuffed because that will mean I will have had lots of fun with it :grin:

Lots have been on about this. On mine I have one open and its a manual but I have seen DSG with the same. Apparently the more recent deliveries are all the same and this is normal. The first models were different but according to the dealers there is no cause for concern so that means there probably is. Personally I couldnt care less how many holes mine has, I just want to enjoy the car, if it goes wrong cos there are not enough holes then I have a 3 year warranty to cover that but touch wood, 2000 miles and the holes have not been a problem.
-
thanks you lots , , because my dealer couldn't tell me weather this is normal or not.Now i know mine is not the only one with no holes .Cheers

If your car is actually at the point of not moving when you depress the throttle then something is not right. I have a DSG gearbox on mine and whilst there is the slightest of hesitations from rest it is nothing more than I would expect from any automatic gearbox awaiting the clutch to act.
If it is that minor and you are going in to gaps in traffic that are that tight (especially with something as big and heavy as a coach) then I hope you are well insured.
I too am getting about 20 - 25 mpg but to be honest I am pretty impressed with that as the car tends to be driven as though it has been stolen quite a lot of the time.
-
I've heard it's the same if you try and left foot brake with the DBW 20vts. The management closes the throttle body.
I've always been against all these computers and wires that drive a car. On the new passat the handbrake is a button stead of a lever connected to the brakes. What happens if the computer messes up and applies the handbrake doing speed? crash. but don't worry, with all those airbags at least you'll be ok!
Even though I've now got a 2003 engine under the bonnet the only modern technology I kept was the injection system giving me better MPG than my 8v when driven sensibley. Drive by cable, no ABS.
I'd like to stay in control of my car not a computer!
It's a serious safely issue you've got there.
-
It's certainly the same on the TT. First got me after driving through a ford and attempting to dry the brakes with my left foot. So heel and toe changes are a thing of the past (obviously already are on DSG versions!) :rolleyes:
-
It reminds me of the lag in the boss's new A3 with DSG. I was probably holding the gas down slighty when I had the brakes on. I planted it to drive past the traffic in the oncomming traffic's lane and then into work's carpark and there was terrible lag before I shot forward.
very dangerous
-
I have a DSG and it has never cut out on me.
The only problem I have with responsiveness is where I put my foot down a bit too hard, and it kicksdown and nearly takes me into the car in front, or shreds 500 miles off the front tyres - but hey, it's all about changing your driving style...
-
Yep.
My MK5 GTi does it too - and its a manual. In fact most modern motors will cut the throttle if you try to double pedal them, most of the time there is a delay of at least a couple of secs. The golf is a bit too sensitive tho.
This is a git as I quite like hounding the GTi - and that means left foot braking to make the it oversteer mid corner (I find that you get a fair bit of understeer if your a little heavy on the throttle). It is dangerous, but my method is to dab the brakes hard which gives you LOTS of oversteer! Keeps you awake.
It would be nice to get this overridden - perhaps when I get it chipped?
-
Ditto - Mpg on manual GTi was lower than that!
-
Yes I'm having a similar problem but not just on pulling out. Engine appears to 'die' for 1 second just at the critical moment of pulling onto a junction/roundabout. This hasnt been a frequent occurrence but how frequent does something like this need to be?
I've had about 9 instances on applying hard acceleration from 2nd/3rd gear and again the engine just 'dies' and in this scenario you physically get jolted forward as the momentum is cut for a second or so. Actually this happened this morning whilst overtaking a bus. Arse.
-
Does this happen to you just in normal Automatic mode, or does it happen in Sport mode too?
-
Mostly in D but also in S too. When I finally convince the dealer to do my steering rack I'll ask them to look into this also.
Again this isnt any kind of turbo lag or auto box delay, the engine cuts out on acceleration.
-
My misses has complained about exactly the same issue, now I can't imagine the dealer doing anything about it but I'm going to speak to Morego to see if they can write over the ecu to overcome it....
-
Update!
I find this has only happened on really hot days when the engine is working so hard with A/C etc.
A easy and effective way to overcome this is to just blip down one on your paddles, it'll reset to normal Drive after 10 seconds or so.
Or you can pay 500 notes and get it remapped to provide more torque, this is an option I'm trying to get the misses interested in :tongue:
-
Seems like this is 'normal' behaviour, as designed :sick:

Well this would put me off buying one (If I could afford one!)

I must say here that, I think you will find the fuel cutoff issue is not isolated or related to the DSG system.
I drive a Manual Mk5 GTi and the exact same thing happens. Usually as you leftfoot trailbrake into a corner with a small amount of power still applied, the engine completely cuts out for around 2 seconds and gradually rebuilds grunt again. This issue really impears my driving style through a series of twisting curves and does verge on dangerous.
The vehicle is a South African build and I am in Australia. WOULD BE INTERESTED TO KNOW WHETHER THE SYSTEM CAN BE MODIFIED .
