Two problems related to headlights have been reported for the 2009 BMW 135. The most recently reported issues are listed below.
The wiring of my 2009 BMW headlights, both sides, has its insulation disintegrate, exposing bare copper wire (as it is made of biodegradable material) to the point where my daytime running lights have shorted out and the adaptive headlight control on the passenger headlight is stuck at an angle that is too high. As these are adaptive headlights, a short here can render the car's headlight in a blinding state. Local shops want to charge $900+ per light housing to completely replace the light assembly.
Wiring inside headlight assembly has insufficiently insulated wiring. The wire insulation is flaking off due to heat exposure from normal operating conditions. This is a safety problem. Fire potential. Lights could stop working while driving at night.
