I'm helping out a friend that bought a used 2003 A4 here in Canada. He's already spent a packet on various engine things but the last thing is the housing for one of the rear license plates lights. The screw that holds the plastic cover has rusted off, and the contacts are broken and corroded.
I'm looking for a how-to on replacing the housing. He's not very handy but I offered to help him out as I have the tools etc.
Any assistance to a parts list and guide would be greatly appreciated. I've searched the forum here but haven't been able to quite find what i'm looking for.
Thank you very much in advance.
