Two problems related to turn signal have been reported for the 2001 BMW 3 Series. The most recently reported issues are listed below.
A recall has been issued for this problem for cars produced from 9/1/01 to 02/01/05. [recall campaign 11v-438: repair ground cable for rear light lamps (side panel)]. I have the exact same problem although my car was produced approximately 14 months prior to the vehicles affected by the recall. Situation one or more of the following lights does not function in the rear lamp assembly, mounted on the rear quarter panel (rear parking light, rear turn signal, and rear brake light). Cause a poor ground connection at the rear lamp assembly (connectors x338 left side – pin # 2 and x339 right side – pin # 3) causes a malfunction of the rear tail lamps.
For BMW e46 2001, rear turn signal light brown grounding wire arches and damages the socket causing the light to flicker on occasion. This problem is also evident in later models of BMW e46 and an recall has been issued on e46 2002-2006 models. It's problematic that they also didn't address this on e46 2001 models because it seems to occur in the earlier model as well as evident with my car.
