Cant you just use D for normal driving, then use the paddles or 'S' for your country lanes etc?
Or do you still feel a more sloppy DSG even in S or using paddles?

....Using D for 'normal' driving and S for country lane twisties and overtakes is exactly how I drove for the first 10k miles or so! Now I drive M with paddles all the time except for in town or traffic queues. Performance driving tuition has taught me to always be in the optimum gear and 'think manual'. S can be useful, say at very busy multi-junction roundabouts, to pop in and out of (but you have to stay for just a second or two in D as you go through or the DSG gets confused).

Try a DSG software upgrade.

http://www.golfgtiforum.co.uk/index.php?topic=105907.0

No interest in the group buy, but they should still offer a discount if you mention where you saw the offer. Some other companies have dsg developments in the pipeline but afaik this is the only one available in the UK right now.

....Will this particular DSG upgrade change the auto learn feature?

I would imagine it needs to override it to maintain the sharper changes. I can't see how it would work otherwise.

Isn't the DSG learning process relative though?

My thinking (I don't actually know) is that the box of tricks would still learn but apply its learning method to whatever any new shift thresholds are (independently) programmed to be.

Yeh thats propbably how I would drive until I got used to the paddles..........

@ ifti

You don't have to leave it for as many thousand miles as I did though!

Paddle extensions help too.

Ifti, yes that is the solution - switch into "M" or manual mode and use the paddles. BUT, the "D" mode (what with the kick-down etc) when driven aggresively can learn your style; so well infact that you dont need use the paddles. But then it decides to re-learn your more sedate style and your back to square 1.

It learns the new style of driving in about 30 seconds.
My comment about the  garage mechanics thrashing the car was serious.
The gearbox learned their style of driving, you gunned it a bit after the service and it seemed sharp.
Then you settled back to a ploddy way of driving and it learned that.

Very clever in my opinion, hats off to Borg-Warner and VW for such an excellent product for everyman.

....You are far more in control if using the paddles and 'thinking manual' than in D. You can instantly override D with the paddles at any time though.

Calling all Engineers: I've noticed that post 'normal' service (circa 10 & 20Km non DSG) the DSG is particularly crisp and performs well.

As others have said, it gets road tested on a proper service, and will also get all the fault codes cleared from the ECU memories.  And if there are any ECU updates (to either the engine or the DSG, or both), then these will also be applied at the service.  These will then set the ECUs back to their 'default' settings.

The Torque converter engages strongly and the cars throttle response appears crisp and lively.

Erm, the DSG does not have a torque convertor.  I has a conventional friction clutch, albeit, a multi-plate clutch, and bathed in oil - oh, and there is a pair of them!  :nerd:

However after a couple of weeks of normal driving the DSG appears to get lazy....the torque converter is slow to engage on acceleration and de-celleration making driving far less enjoyable.

Can you please try and describe how the actual gear shift points are changing?

I've proved that this is DSG control/ ECU related by power cycling the car and the result is a return of super crisp performance and zero DSG Alzheimers.

LOL ^^^^

Seroiously though, if you are finding that the DSG worsens, then you must be driving very sedately!  :wink:


Does anyone know how to stop the DSG auto learning as it's rubbish.

Don't think you can.  Virtually all modern auto transmissions now use adaptive shifts.
