An Audi dealer where you got the flash wouldn't need to scan it since they already know your car is tuned since they are the ones who tuned it. I still think that if you have a good relationship with your dealer and they installed the said upgrades, they're not going to screw you over.

 

Yet another reason to buy used. Save your money, mod it however you want, and just know going in that if it blows up, it's on your dime. Too much red tape, too much hassle dealing with dealers Most of us aren't happy with their level of service anyway, now we are upset when they won't work on our cars. I suppose in this society it's asking too much to spend more on quality control than on a good warranty.....I digress
