Hi,
I recently had my Audi A4 at an auto electrician, to have a new BCU programmed.
I was informed by the electrician, that the replacement had the wrong code on the front and would need to source one with the correct code.
During this attempt to program the wrong BCU, it has corrupted the cars electrical system. I then supplied the right BCU, but by now, the system was corrupted and there was nothing more they can do .
It is in Limp mode and nothing seems to work correctly.
I am now at a loss, is there anything anyone can suggest?
Thanks in anticipation,
Liam
