The insulation on the internal wiring of the headlight (left and right) have fallen off the wiring leaving sections of conductor exposed creating shorts in the lighting system. This is a known problem in the BMW community (owners and BMW) since at least 2011. This is due to the use of bio-degradable wiring by BMW that breaks down prematurely. Replacement headlight assemblies (high intensity discharge Xenon) are over $1,000 each. Both halogen high beam lights are inoperable which reduces driver vision at night on suburban roadways. Re-wiring with correctly specified wiring is possible but requires specific skills and experience. This is a known problem which BMW has hoped would go away as few of their cars of this age are on the road. This risk assessment driven policy should not shield BMW from fully addressing their failures in material selection which impact safe use of their cars.

What owners say
Inside headlight wiring insulation became brittle and falls off leading to potential shorts and equipment failure. Additional wiring throughout engine compart shows similar degradation and failure. Split wire housing to protect wires from engine heat also show signs of decay, exposing wires to excess heat and inducing failure of insulation. This is not a turbocharged engine and has lower engine compartment temperatures. This problem started 7-8 years ago and has gotten worse.
All wiring within the headlight assembly is deteriorating and exposing the bare wiring internal of the assembly. This is causing electrical shorting, electrical fault codes, and occasional periods of inoperative headlights while driving. The wiring issue was first noted by my mechanic around february 2019. I have found thru my research for repairs this is a very common problem.
Degradation of headlight wiring. Wire insulation is flaking, cracking, and internal conductor wires are exposed. Causes intermittent headlight issues as wiring shorts during driving.
While replacing parking light bulb I found insulation to bulb holder falling off, likely due to heat inside headlight assembly. Given the brittle insulation falling off, a short could easily have occurred. The inner cv joint on the right drive was found to be without grease. With no grease fitting or means of inspection, the axle could have frozen, causing stability issues.
The wiring harness inside the headlights is crumbling away causing lights to intermittently not work. The wires spark when they touch together. This is a fire hazard.
All headlight wiring shielding has deteriorated in the unit causing a shortage. This is a safety issue not only due to the shielding possibly causing a fire, but also an issue for safe driving as the lights no longer function to dot requirements.
