Two problems related to exterior lighting have been reported for the 2007 BMW 550. The most recently reported issues are listed below.
Experience "highbeam malfunction" warning light. Inspected the headlamps (e60 adaptive xenon part # 6312710157). The driver's side low-beam halogen melted through reflector. Inspected wiring and the sheathing / jacket were disintegrating causing short circuiting. Upon further research, this is a result of BMW's use of biodegradable materials in mid-200's cars. Not only is this a fire hazard, the only remedy is to get a new headlamp set (~$1300 each).
About 3 months ago I bought a 2007 BMW 550i with 29,802 miles. When a large red steering lock light appeared on the dash, as well as, the center console computer had instructions "not to turn the engine off". The car operated normally just with an uncomfortable big red light on my dash. Before calling the BMW dealer I decided to do some research on the internet. I have found dozens of BMW forums referencing steering wheel lock malfunctions. Most were ranging from updating computers to steering column replacements. I took the car to the BMW dealer as he gave me a loaner and took my car for the night. The following day he called me in and told me I needed to fix this problem that would cost me $700 or the steering might lock up on me during driving. With this many similar complaints it sounds like there might be a recall on the BMW steering lock?.
