general problems of the 2006 BMW 530

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.

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.
