I have an 2012 135i and just installed (PnP same model as my non-black) a new set of tail lights blackline original 63212225282 from Schmiedmann.
But im facing one isssue, one of the driving light (driver side) will not light up, break/turn light etc. is working fine. I have checked all connectors - all good but still no driving light, so i decided to install the old one again, but this now have the same issue. I have checked fuses and is now out of ideas
Any suggestions?
