I noticed my Audi 80 experiencing issues with startup and acceleration, and after some research, I suspect the fuel pressure regulator is the culprit. How can I accurately diagnose and repair this issue?
ReplyFirst, check the fuel pressure using a pressure gauge and compare it to the manufacturer's specifications. If it is too high or too low, then the regulator is likely the issue. As for repair, it is best to replace the entire regulator rather than just the diaphragm or other individual parts.
