Is my FRM toast? Tail light issues.

[pzzvv]

Issues with my lighting started occurring a few months back. (2009 E90 M3). First, my rear left outer tail light went bust. I went ahead and replaced it. Problem solved. Front right headlight few days ago.. replaced bulbs. Problem solved. But the persistent issue has been my rear right. Turn signal is malfunctioning and I get an error code when trying to use the turn signal.



These are the codes that I currently have:

C5AE: Connection of head unit to SDARS antenna base: line interruption

A8C4: Break force display right, E92/E93 or US: 2nd brake light defective, E84: rear light right defective

A8C3: Break force display left, E92/E93 or US: 2nd brake light defective, E84: rear light right defective

A8B7: Right brake light defective, PL3 from 07/14 and SA5A1: For lights LED faulty, PL3 from 07/14 and SA896: Daytime running lights halogen right defective

A8B6: Brake light defective, PL3 from 07/14 and SA5A1: Daytime running light LED defective, PL3 from 07/14 and SA896: Daytime running light halogen left defective

A8B3: Direction indicator right rear defective


I did order a new right rear that I'm going to pick up tomorrow but not sure if that will sort the issues as it's also showing my left side issues.

Any thoughts?

Check your front right fender liner if any of the wires going to the wiper washer pump is damaged. When mine was damaged from wheel rubbing it caused weird brake light errors.

Will take a look. I do rub quite a bit up front so this is certainly worth looking into.
