My 2005 Audi A6 was just returned from the workshop. I was informed I needed a new ECU since the Bluefin (superchip) I inserted may have spiked the ECU and their diagnostics couldn't read it.
Is there anyone who knows if the ECU can be repaired?
The automobile was first taken in for maintenance because of juddering acceleration under load, which they claim is caused by the engine overboosting.
I'm not sure if $1,000 for the ECU will solve the problem.
