Gunner 0 Report post Posted October 28, 2010 (edited) Done a bit of searching online, but still can't find a solution for my problem. I replaced my Aftermarket Depo Lights recently with genuine BMW Clear rears, even with genuine lights, im still getting a tail light failure warning on my obc. I've checked the bulb connections and theres no corrosion, all the lights are working when i check them but haven't checked the wires in the boot hinge yet. Could that be the problem? EDIT - Checked to make sure all the bulbs I am using are correct also Cheers Edited October 28, 2010 by Brenton Quote Share this post Link to post Share on other sites

jochen 4 Report post Posted October 29, 2010 Hi Glenn, Its Saying Tail Light Failure as soon as I put the put my headlights on. Cheers The lamp check system checks for faulty bulbs. Any poor wiring connection, bad ground, old filament, or corroded bulb connection, or worn down solder lump on the base of the bulb will cause these problems As well as burnt out bulb! Make sure the taillight connectors are clean and in good order, and that the bulb socket is clean and free from dirt and rust Make sure the taillamp ground connection is also clean, secure, and free of dirt and corrosion If all looks good, check the bulb socket that it makes a good connection with the bulb. Then check the bulb itself - often the solder blob in the base of the bulb wears down due to vibration and the bulb stops making a reliable contact. Replace the bulb if this is the case.

Gunner 0 Report post Posted November 16, 2010 (edited) Just check mostly everything you've said and everything seems to be fine. Just wondering if my wiring harness is correct. On my passenger side taillight there is 6 wires going into the harness but on the taillight there is only 5 pins + 1 blank hole. On the drivers side there is 5 wires going in and 5 pins in the correct place. So would this be causing a problem. Heres a few pictures of what i mean. Sorry for the bad pics, an e63 camera sucks. Edit: Also checked the high stop light wiring and it appears to be correct, goes on when i press the brake pedal along with the other brake lights.

Gunner 0 Report post Posted November 16, 2010 (edited) Okay thanks Brent, I guess i'll just live with the error code for now since its not actually effecting the lights. Edit: Think i may have found a solution for me. Mite give it ago tomorrow. I think my old depo lights had a bridge cause i remember wondering why there were wires soldered onto it http://m3forum.net/m3forum/showthread.php?t=238876 Edited November 16, 2010 by Brenton Quote Share this post Link to post Share on other sites
