Well, I always drive in either DS mode or M mode (paddleshifters), and today I was driving along and suddenly, without me touching anything, the red screen that shows what gear/mode you are in turned into 'D.' I tried moving back and forth between D and DS and the screen wouldn't change. The paddleshifters stopped working completely and so did the norm tiptronic. I couldn't even drive in DS automatic... It stuck in 'D' mode.

Also, again, since I've really only driven in DS and M mode, I don't know if this is the normal way the car drives, but the car would only really rev up to 4,500 rpm before up-shifting, and once it up-shifted it wouldn't down shift until I came to a complete stop. In DS mode, the car would rev to much higher RPMs and would also shift-brake (downshift to make breaking easier) and would downshift if I gave the peddle a little push to go faster. This part could be normal though, since I don't know how 'D' works.

The problem happened twice today, but after I shut the car off and turn it back on everything seemed normal. But when I started to drive again it switched on me after I would say about 20 minutes of driving in DS mode with paddleshifters.

I hope I explained the problem well enough, please ask questions for clarification!

PS: The car was literally serviced last week and it passed service perfectly... maybe they touched something in the car's computer though?

Thanks for any help!

 

Take it to the dealer when it happens again. Be sure not to turn the car off so that the problem does not reset.

 

this perhaps
