How not to get rid of bulb out error.
What you can’t see can hurt you. Luckily this bulb burnt out before burning anything. A bulb error for the customer caused confusion (and surprise for us). We found this wrapped tin foil inside the trunk of this car. Not to worry. Some new plugs and proper wiring coupled with our coding knowledge had this Audi A4 with LED plate lights back to factory standard in no time.
