This is a late post but...
I purchased my Mk6 TDI with about 50,000km done. Serviced the DSG at 60,000km. Since owning the car i would (most times) notice (more than hear) the change into 1st as the car stopped at the traffic lights.
Take off engagement and up changes were OK. I drive reasonably conservatively around town with light throttle take off and gentle coasting stopping at lights (no hard last minute braking) but give it a bit of a work out in the hills, often using S mode.
At just over 80,000km the take off engagement was starting to lag and by 90,000km down changes from 4-3, 3-2 were becoming noisy & felt. 2-1 about the same.
I was getting pissed off with this and when i get in this frame of mind i tend to give cars/bikes a bit of grief driving style wise. Italian tune up.
I worked the DSG hard, manually changing up & down thru 1-4 as hard as the DSG would let me at the highest rpm the DSG would allow. I cycled the changes as often & hard as i could for about 5 minutes. Sort of fix it or f#%k it.
Next day, the DSG was noticeably different. Take up or engagement from stand still was instantaneous and soooo smooth and positive. Up-changes seemed more +ve and seemed to hold a gear a bit longer. Down changes have improved with the 4-3, 3-2 clack now
very infrequent.
I spoke with a reputed German Auto specialist and he said i had likely done a form of DSG reset. Maybe it was due to more forceful oil circulation thru the galleries, removing glaze off the clutch plates etc or even in the DSG brain. What-ever.
I have only done about 300km since the 'reset' and it is holding. Longer term??
I am of the opinion the DSG needs a bit of a work out occasionally as driving the car like a pussy does not tax the DSG, and in reality, i think it is a high performance piece of equipment that needs to be used as intended.
Next up is a change of DSG fluid and another 'reset' drive.
If anyone reads this and gives the methodology a try (at your own risk
), i would be interested to hear your results.
cheers
