E90 LCI LED Taillight failure. Repairable? Cheap replacement?

akasnow · 05-05-2015, 11:06 AM

Hey guys, so I got a dreaded check bulb error randomly while driving and using blinker. I'll get a fast blink, and then sometimes it blinks fine with no error. Seems intermittent... but some LEDs on my RH Tail seem to be toast 100% of the time, whether I get an error out or not. '09 E90 LCI. Anyone dealt with this personally before? Reputable cheap replacement? Swap out boards on the back of unit possible? Thanks for the help!

TL;DR: 3 LEDs out on RH E90 LCI Tail. Other LED in cluster work part of the time. When I get bulb check error (usually while driving and turning on blinker after some bit of driving) then the other LEDs flash erraticly and are very dim.

Here you can see how it looks with no Error on dash:

Here is how it looks when the Error is present on the dash:

Are you sure it's not the cable that runs into the trunk lid?
Mine was bad and required repair. It had three broken wires.
I had the same issue on an e36 M3.
