DSG reset/basic settings (vcds) solves jerkiness temporary!?

[Timvgti]

Hi guys,

I have a 06 2005 GTI MKV (ABT remap 240ps) with DSG.
Bought it in october 2010 (a year ago).

Noticed that it 'hesitates' a little when driving off slowly (citydriving/trafficlights/etc.). So from a standstill, gently on the accelerator, it feels like it 'jumps' a little around 1200rpm. Like it wants to go faster.
Feels just like a little 'hop'/'hessitation'/'jump'. Then goes normally/smoothly into second gear and from then everything feels fine!
Is first and second gear something like 'cooperating gears?? with dsg?
So only problems in first gear, starting from a standstill. When the car already rolls (like in traffic jam) it's already in second gear and everything feels smooth when accelerating from that point.

A friend did a DSG reset/basic setting some months ago and after a testdrive the car felt different/driving off from standstill felt way better/smooth, just as it should.
But the last time I noticed that the 'hesitation/stutter/hop/jump came back when driving off from standstill.
Today I did the same dsg reset/basic setting ( http://wiki.ross-tech.com/wiki/index.php/6-Speed_Direct_Shift_Gearbox_(DSG/02E) ) again and went for a small testdrive in tiptronic mode.
Car feels smooth again, driving off from standstill.
Haven't had time to do the full suggested testdrive yet, but will do so tomorrow.
(Drive in Tiptronic Mode from stand still up to 6th Gear.
 While doing that make sure to drive in Gears 3 or 5 for approx. 5 minutes and also in 4 or 6 for approx. 5 minutes.
 The engine speed window for all gears is 1200 - 3500 RPM (for clutch calibration).
 Perform one sharp braking followed by a full throttle acceleration (oil return check) while in Drive, Not Tiptronic Mode.)

How comes that this problem came back?
Something wrong with my dsg? I don´t have the common dsg faillures, no faultcodes, dsg oil is changed when I bought it last year at VW (10000miles).
Do I have to worry?

Thanks,


Tim

Could it be because I'm stuck in traffic and forced to drive like a granny a lot of the time?

Do the problems occur when it's warmed up?

[Timvgti]

Warm or cold, no real difference.

[Timvgti]

No sorry, update: remember it was more noticeable when engine/transmission was cold.

From your description the hesitation is in 1st gear not when it changes?  Or do you mean when it shifts at 1200rpm to second gear?

If you have it in tiptronic and use the shifter to change at higher rpm 2000 or above but not high does it still do it or only in D at low revs gentle pull away?

I have something similar on my car not sure if its a DSG problem think its more rev matching at those low rpms.

You should also increase the amount of manual driving you do as that improves the DSG changes (well improves mine anyway)

Did the vcds full reset/adaption again. This time with the full suggested test drive.
Car feels smooth and as it should. But scared it comes back.
With 'it' I mean the hesitation when I drive (gently) away from a standstill.
I could feel it in first gear. Not when switching to second. Happened in d tiptronic and s.

Now, after the reset everything feels fine and I notice it goes from first to second gear also when you just let the car 'crawl' from a standstill. So no foot on the accelerator pedal. You can't feel the switch, you just see the number on the dash change from 1 to 2 within seconds of 'crawling'.

OK, no problem - I had a problem with my mechatronics unit but if it's that then normally the problems only occur when warm!

[Timvgti]

After the full reset/adaption with the suggested testdrive, the car drives as it should. Drives off smoothy again.
Hope the 'hesitation' doesn't come back soon again (a vcds reset once every 6 months is good for me, but not more often).
How comes that the 'hesitation' came back last time after some weeks/months? (can't remember the exact date that a friend of mine resetted it the first time)

It could depend to some extent on your driving style (the 'box "learns" how you drive) and how much or little time you spend in manual mode, as well as the environment in which you are driving (back road blast or commuter creep).

It's normally the case that I occasionally get a momentary hesitation/neutral when I select reverse. It's just the clutch taking time to select the cog. Sometimes it happens when I pull away, in exactly the manner you describe. Not very often, more when cold and only ever when transitioning from on the footbrake to the gas. My personal experience is that it's not present if I'm in manual, and I usually am. I have reset the DSG on one occasion & got improvements which have stayed, but the car is having it's 4 year & DSG service soon. That should make more difference. Has your car had a DSG service & oil/filter change (40k miles/4 years whichever is sooner)? That may contribute as well.

It's not a mechatronic issue in my case, I'm quite sure, as the car is as smooth as silk.

My car had the dsg service 15.000km (kilometres!) ago, when I bought it second hand at VW (The Netherlands).  So should be good...
I use the manual mode just for 'fun' and this is not happening more than once a week.
Also a lot of city driving and stuck in traffic.
Guess I have to use the manual mode more often.

I have the same problem with my wife's 33,000 mile 2007 ED30. I've reset it 3x now, no fault codes and it's running the latest software. It's worse when warm on mine, but it is doing exactly what you're saying.

And after the reset, how many days/weeks/months does it take to come back?

[Timvgti]

'Oli' answered with a PB that the hesisation came back after just one day...
Mine's still smooth after the last vcds reset (6 days ago)...

[Timvgti]

I also notice that the hesitation comes back. Especially when engine/transmission is cold.
How comes?
What to do?
Change oil and do the reset again?
