Hello sifus,my E46 318i 2005 gave a tail light error indicator recently... but when I checked, all lights seemed to be working. It goes off after I restart the engine. It would stay off for a few days and occasionally come back on. Each time, it'll go off if I re-start the engine.I don't know whether it's the wiring or the sensor that's gone cuckoo... it's not a major problem, just an annoyance... just wondering how much would it cost to fix... if not too much, then might as well fix it lar.Anyone had experience in this before?
