See all problems of the 2008 BMW 535 🔎.

Insulation on wiring inside headlight assembly has fallen off exposing bare wires. This was discovered when replacing bulbs. Discussion boards on web have many owners reporting similar problems. BMW does not.

The wiring harnesses in the tailgate have been both severed and otherwise damaged by the normal operation of the tailgate and liftglass. The hinges and wiring trays have sharp edges and the wire insulation material seems to be of a pvc material. It appears that this material is vulnerable to failure with only regular operation of the vehicle, however, the sharp edges of the harness tray in the tailgate hinges act as shears that have severed the wires. This presents several safety issues including the potential of fires from electrical shorts, malfunctioning and damage of control modules due to electrical shorts, inoperable rear-defogger system, inoperable keyfob remotes for entry and locking, loss of radio system including weather band for safety updates, etc. This appears to be not only a common problem, but every vehicle in this designation has either suffered from these problems or is susceptible. As noted in several blogsites where owners and repair specialists have commented, this is an obvious design defect that should be addressed by both NHTSA and the manufacturer. Clearly a recall and manufacturer-paid repair should be implemented.

I ordered new light bulbs to change out my halo angel bulb lights (runningparking lamps) . Which said they were out on my screen inside of the BMW . When I twisted off the housing cap in the back ,the wiring inside of my headlight housing which turns on my parking lights left and right is totally degraded and flaked off ,the copper cables were touching everywhere . I read this is because germany use biodegradable material but this is a very dangerous fire hazard for driving on the highways and road in florida . We as 5 series owners for these years need a recall of new harness with better wiring . Even if you buy a new housing it will do the same thing in 4 years gauranteed . You would have to find some one to rewire it with the same cables Ford uses so it can last 20+ years . Please fix.

Insulation crumbling on all wiring inside both headlight (driver and passenger sides) units resulting in malfunctioning headlights, running lights, and marker lights. Unfortunately, a common problem and a huge safety concern. Issue is exacerbated but not caused by heat. Insulation on wiring to navigation, radio/media player, climate control unit, or ccc (car communication computer), crumbling causing malfunctions to occur in all the above sections. I suspect much of the car's wiring to be in similar, poor condition. I have read that many european cars from the '80s, '90s through the first ten or so years of the 21st century used a soy based, biodegradable wire insulation as part of a "green movement". This early implementation of said wire does not last much longer than 10 years, much less than that when exposed to heat. Please see: https://www. Bimmerforums. Com/forum/showthread.
