Resolved Question:

The airbag light has recently come on in my 08 A5 Coupe.
The fault codes are:
1. Power Supply Upper Threshold exceeded.
2. ECU Malfunction Internal Electronic Failure.
I guess the ECU needs to be replaced, but I am slightly worried about fault 1 - could this mean that the input power supply voltage is too high for some reason and it may fry a second controller?

Hello, welcome. My name is***** will do my very best to assist you with your question. I apologize if you have been waiting long for a response.
The first code sets anytime the ECU is failing on these vehicles which is what the second code means. Replacing the ECU will solve the issue.
