My front fog light (right side) do not work and don't pas the MOT. Ask my local service dealer to replace both side bulbs. Got my car back, same problem, right side still don't work.
Return the car. Service reply, bad earthed. Next day, same problem.
If it was not properly earthed, I assume both fog lights would not worked? I believe the fog light wiring harness has a common ground? Can anyone confirm? Where is the fog lights wiring earthed? Any other pin points to look for?
