Finally got around to running VAGCOM on my re-mapped Q7. No error messages reported to do with the engine management. I think it all looks dealer friendly now.
People keep asking me about the fuel economy. Initially my fuel economy increased by a whopping 0.1mpg. However, as I do a lot of town driving I would say this is probably about -0.2mpg now I have been running it for a while.
The performance and driveabillity far outweigh the slight drop in fuel economy. Lets be honest, you don't buy a 2.5 ton behemoth and expect 50mpg.
Hope this info helps!
