Thats what happened.
Not so long ago the engine warning light came on on the dash. So, i phone audi and let them have a look at it. First reply was "its been remapped, we arnt touching that!"
Took it back saying i need it fixed, its nothng to do with the remap, they had a look, and came back with " the whole ECU needs to be replaced!"
I questioned it loads of times saying i have never heard of an entire ECU being replaced but apparently it happens all the time!
In hind sight, after the replacement ECU was installed the car is running really well, so it should for Ł650.
Has anyone else heard of this? An entire ECU replacement? I find it a bit odd....
