Have a 2013 TT and recently did a TSB for the rear diff. (REPROGRAM
RA REAR-DIFF. LOCK) and when the car goes into 4th gear the car is a bit jerky. Kind of feels like I am mis-shifting or something... Contacted my dealer and will bring it back in but wanted to see if anyone else has had this issue... I can duplicate the issue anytime and it only does it going into 4th gear.

 

I believe I have done this update recently. Actually, there were two updates. One was for PTV equipped cars. I haven't noticed anything unusual. Good thing you can duplicate it so you can have it checked by the dealer.

Let us know how things go.

 

Hi did you find out what was happening, is there another update to remove the jerkiness?

My 2010 (UK car) is very jerky when cold from 5th to 3rd, like I missed the shift completely then it recovers itself, have asked the dealer to check for updates?

Thanks

 

Took into the dealer a month or so ago and did a road test with my SA. He felt the jerk right away and scheduled me to come in this Friday. I'll post what they find out at that time.

 

What did the dealer say?

 

She's still in the shop awaiting a new transmission... Here are the updates as I got them:

Just wanted to let you know there are no codes stored for the Transmission, fluid level was good. We performed a re-adaptation to the Transmission and concern is still present. We submitted a technical request to Porsche and I am awaiting feedback from them and what to do next.

Porsche had us perform a service bullitin which consist of a reprogramming. We performed this with no change so we are waiting to hear back the next steps.

 

Mine seems to have settled now, must have been learning my driving style, is there a way to reset it like Mercedes and other brands can (hold accelerator for example)

Thanks
