So i just got a new pump installed last week via warranty and I am already having problems. Normally when you start the car you can select Tarmac/Gravel/Snow before you move, then while the pump is warming up or building pressure for maybe 1-2 minutes if you try and change the mode it will flash at you. Eventually once everything is going you can change it when ever you want.

Now i can adjust the T/G/S mode before i move. Once the car has moved the T/G/S logo is gone and operating the switch does nothing. No CEL, No codes.

 

Today i now get the "Service Required" for the drivetrain warning. Still won't pull any codes. I am scanning with EvoScan 2.8 using "EVOX EFI"

 

If you're having problems under warranty, best bet would be to take it back to the dealership and have them fix the problem.

 

Bahahhaah pump is bad. New one is on order. This must be some kind of record - 1 week failure.
