DSG Change down

[micalee]

Does anybody with a DSG have this problem with their change down? Noticably more in manual setting, when the car changes down, you get that lovely throttle blip but the car also surges forward when it does this! Surely this needs to be automatically revved in a neutral state to prevent this as you would do when double de clutching?

Dont know if I've mis-interpreted this, but that sounds dangerous to me 

I was beginning to think DSG would have been a good idea given how much everyone on here seems to rave about it but glad I went for the manual now!

No, nothing like that on the GTI.

Is your R32 standard or modified?  Are you touching the throttle pedal?  Try changing down at a constant speed with constant throttle opening, then try again whilst accelerating with more throttle (but not kickdown), then try a third time with feet off the throttle and brake.

You may need the dealer to re-flash the DSG ECU, or they may even be a new map.

I have been able to "confuse"  my DSG box, but that is to be expected and is not a defect or problem.

This happens whilst my foot is off the accelerator and also if i am braking and going down through the box. How do you mean you can confuse your DSG? The car is standard

when he says confuse, I think he means confuse the electronics?

Confuse DSG box:

I take it you know that the DSG box works on pre-select - ie, when you are in 1st gear, 2nd gear will be engaged on the shaft (preselected), and when the upchange is called for, either by manual control from the paddles or shift lever, or by full automatic electronic control, the clutch for 1st gear is released and the clutch for the 2nd gear is engaged.  Understood??  OK.

Right, the next thing to understand, is the box can only preselect ONE ratio - when you are in 1st, it can only preselect 2nd, and when you are in 6th, it can only preselect 5th.  Still with me?

Now then, if the box is in either 2nd, 3rd, 4th, or 5th - then the box can preselect either the next higher cog, or the next lower cog - keep up at the back - this is where you can confuse the box.  If you are gently accelerating, at a linear rate, in "D" mode, and it has changed into say 4th gear, the box will have preselected 5th.  If you then paddle shift DOWN, the box will get "confused" because IT thought it was going UP, but you just decided to go DOWN, and has to swap the preselected cog before the actual change will take place.  You will notice quite a delay in the change, and it sometimes feels as though the car has become "bogged down" for a few moments, before picking up its' heels and rocketing off! 

I hope you havn't nodded off - I'll be testing you later 

Micalee - it does sound as though your box has a prob, as off-throttle downchanges, whilst they can be felt, are normally very smooth.  What's it like downchanging in full auto "D" mode?  How many miles has your R done, are you the orginal owner, has it done it from new?  Any other nuggets of info would be useful.

BLIMEY CHARLIE!!!  Thats a very detailed synopsis, thank you.


OK, my car was new from Sept 06, I am the only owner from new and it has done 3000miles approx. It did this from the start also. In Auto "D" mode, it still lurches forward as it drops down even with foot off the throttle. I have tried at all speeds, but seems noticably more when in manual, either in tiptronic or on the paddles.

Well there's no point pansying around with a de-caff cappuchino, when only a dark roast double espresso will do

What about revs - try changing down a quite low revs, and also quite high revs (aim to change down so that it nears the red-line [obviously when the motor is at the normal operating temperature] on the next cog lower - don't worry, you can't fec& it up, it has a fail safe override to prevent over-revving).

I'd still get it back to the dealer mind you . . . Rgds

You make me laugh - Ill try the different change downs on the way home tonight. It is booked in with the dealer next tuesday. They will look at this issue plus the steering problem i have!

It must be me and steering, cos we just bought a new shape corsa and the steering on that is awful! Although it feels fine (sounds contradictory) when driving, when you turn a corner say and let the steering go light in your hands, the wheels should automatically straighten up! this doesnt! Its really hard to describe - it feels like whereever you place the wheel, it stays there as though something has been tightened up to much!

It is most perculiar so i am returning that also.

I'm an ex-crab  , so we both probably share a warped sense of humour

The more info you can give the dealer, the more likely they are able to fix it first time, rather than fobbing you off time and again.

Ohh . . . that's not right, is it?

On the other hand, there seems to be a common prob to both your motors, and I think I may have the solution. . .










It might be a nut . . .





 . . . you know , near the steering wheel . . .







 . . . yesssss . . . the BIG NUT that is holding the steering wheel
