Seat can NOT detect remaps like Revo/AMDs. So what Seat do is if they need to check, they will take out your ECU and Seat then send that 2 Seat UK, and Seat UK then send it 2 AMD Technik 2 test it, because they can read remapped ECUs and Seat cant.
That what i got tolded by the MD, because if Seat can not fix your car then Seat UK will ask AMD 2. Thats why i took it 2 them, because it would of been took 2 them in the end any way.
