I just came across this : VWVortex.com - TD1 warranty flag It seems that Audi (US) have a way of checking if a car is mapped, and they are using it to void customer warranties as a result. I don't know if Audi UK have a similar system, I'm sure they will have it soon if it's not in operation already. This affects people like me who have another 8 months of warranty cover but want to get their cars remapped. Worrying...... I wonder if they will use it to stop any recall work being carried out in future (like the coil-pack recall that was done recently) by claiming that remapping would lead to the parts failing. I had some recent warranty work carried out but as my car has (to my knowledge), never been remapped, they completed the work without any questions (Intake tumble flaps / solenoid). Has anybody (with a remapped car) had any warranty work carried out recently? Would be interesting to hear if anybody has been affected.
