Hi,

I have an Audi TT 2017.
Does someone know how can I reset my ECU so that Audi will not know that I an ECU upgrade was made?
I want to try to keep my warranty.

I checked with VCDS and I see this:

Flash Status
Programming Attempts(application): 1/1/1
Successful Attempts(application): 1/1/1
Programming Status: 00000000
Flash Date: 16.02.17

Thanks!

I've read that you have to go back to an APR dealer who flashed the ECU and have them flash it back to stock.

I've also read this may or may not totally deceive Audi and that they may still be able to see that you have/had a tune.

I did NOT flash mine back to stock and Audi will not warranty my drive train, but I'm ok with not deceiving them.
