Hi,

I have a MY04 Cayenne-S. The tiptronic switches was working fine since got the car; today not working after back from dealer by doing a TCU (transmission control unit) adaptation coding. But ending up not working with the TCU I brought in; still using my old TCU. Talked to the dealer they said it has nothing to do. I don't know what to do neither. All other buttons on the steering working except the tiptronic rocker siwtches.

The tiptronic from selector lever is working fine!

Can anyone help please? Thank you!

Does the gear select lever on the centre console change gears when you put it in manual?

Yes it does; the manual up and down no problem; except from the steering!
