A DSG question

[Top Cat]

Have my car back from the dealers after getting a new mechatronics unit fitted. 

And when i started the car at the dealers took my foot off the brake and the car didn't move.  before i it was fixed, as soon as i released the brake it would pull forward, So much so that i have never had to use the accelerator in reverse.
So this got me thinking whether my mechs unit was defective straight from the factory, as it has always done this pull forward from new.

So what does yours do when you just take your foot off the brake.

Mine pulls forwards, in either gear unless its on a incline in which case it may stay still or roll backwards until I apply sufficient revs.

My previous DSG car a Leon TDI also creeped in both forwards and reverse gears, as does my dads new A5 sportback 7spd DSG.

Mine gently creeps, rather than pulls hard, in either D or Reverse.

all auto's 'should' pull as far as i know, and shouldnt rollbackwards if on a hill, it should hold still.

Id say that they have now broken your box! not mended it!   or maybe not set something correctly! 

[Richn83]

Yeah sorry probably bad use of the word pulls, its only a creep hence it easily gets beaten by an incline!

i really dont think it should roll back, none of the auto's ive driven have rolled back whilst in D

^^^^
Agreed, I don't think it should roll back unless the incline is pretty extreme. The GTI has a feature called Hill Assist which stops it rolling back in normal circumstances. It's described in the Handbook.

i thought hill assist was just applying the rear breaks on a hill?? in which case the manual's would also have it, mine doesnt have it. (unless its an option) my old subaru imprezza did though.

[Richn83]

Im not convinced about the hill assist, its supposed to give 2 seconds of hold to allow you to switch pedals, and I cant say ive noticed it, and I am talking about some reasonable gradients about 30-35 degree gradient but nothing that has a warning sign.  Ive used the hill hold in the newer cars and that definitely works.

[Saint Steve]

Hill hold is only a factory option for the passat or later dsg cars.

Its not on the mk5 GTi at all. My Passat B7 had its own button in conjuntion with the Electrically operated hand brake which has Hill hold.

All 3 of my Mk5 DSG cars have crept foward  and all of them on a very steep hill, all rolled back unless you apply the Handbrake.

The few i have test drove have all creeped

Ditto to the above ^^^^^^^^^^^^^

maybe its relearning and it will creep after some use?

Sound's like the full adaption has finished on the new ecu

Mine creeps slowly...the rate of the crawl varies depending on the driving behaviour beforehand. 

So, for instance if I'm on the motorway and I have to stop and then let the car crawl...it does it at a different pace to say first thing in the morning.
