Driver side EBay LCI brake light not working
Need a little insight. I’m not sure what’s going on with my 2019 540. I installed eBay LCI tails about 1 1/2 years ago and everything was fine. My battery drained about a month ago and I had to jump it. Since then the drivers side inner and outer brake light doesn’t work. The light, reverse light and amber works fine. It’s just when the brake is applied it doesn’t get brighter as the passenger side does. I ordered a new set of lights and it’s doing the same thing with the new set. Any ideas as to what could be the issue?
Thanks!! |

There was a mention here a while back that eBay tails can cause the LCM to generate a "permanent" error that can only be removed by the dealer. The error causes the LCM to disable certain functions, which in your case would be the brake light on that side.
Have you scanned it? |

I wonder if a good remote coder with ISTA could clear the fault. Someone like Vic.

I definitely learned a new thing here. I had no idea there were “permanent “ faults. Good luck.

As far as I remember, the issue with permanent faults is discussed in the 1000 pages long "aftermarket/eBay tail lights" thread. I stumbled upon that particular post when deciding if OEM was worth it vs cheap replicas.
I agree with Joe in that it's probably not worth it, especially if you score a good deal on a genuine set of tail lights. Vic strongly recommended against replicas and told me the euro version (no matter what G30 version you have) are the best ones. |
