problem #2

I have a 2001 BMW 540ia [xxx] and all the external lights are gradually failing. In all cases the lights bulbs are ok. First the passenger side rear turn signal light failed, then the drivers side daylight running light, then the passenger side reversing light, then the passenger side brake light, then drivers side high beam, then the drivers side front turn light etc. Failures were over approximately a 2 week period. The most disturbing thing is the onboard computer is showing all the external lights working correctly. My BMW mechanic tells me the fault is in the onboard light control module (lcm). I consider a failure of this nature to be completely unacceptable in a 4 year old vehicle and a serious safety defect that has the potential to result in an accident. I have reported the problem to BMW na, so far they are not interested in investigating the problem.
