You can try and tell the dealer to not scan the car, but Audi requires every car getting a full scan, with running a spec/actual comparison. And each dealer is supposed to be running the newest versions of ODIS, which is constantly changing and updating to detect modified ecus.

I guess we will find out, this discussion has raged all over audizine c7 page. What is interesting is I never did anything with the rs6 after getting apr stage 1, never had it flashed back to stock prior to 35k service etc...
