BMW 550i Repair and Maintenance
A guide to problems, costs, maintenance and repair for your BMW 550i
BMW 550i Problems
A creak or squeak can be heard from the top of the front or rear doors. This noise is most noticeable when the windows are fully up. The noise is caused by the decay of the flocking material on the door seals. New door seals, Teflon tape, special lube, or a combination of all of these may be needed to eliminate the noise.
If the brakes are squealing, there's a good chance it is the brake pad wear sensor. A new design was implemented in January 2006 and can be identified by its green color.
I spilled water on the control module and now it's not responding. I'm hoping it will dry out but if not, I need part number if possible.
BMW 550i Questions
I have 95K miles on my recently purchased 550i. The car is very sound & no problems. High mileage will result in future repairs. I already had to change daylight lamps with corroded cables.
Just preparing for upcoming repairs that may be covered by the x warranty.
master cylinder and booster were replaced and brakes bled, car drives about 3-4 miles and then the brakes start to slowly apply until they lock up, turn car off for 2 minutes and brakes reset/let go and car can drive for 3-4 miles until same problem occurs.
BMW 550i Recalls
The front passenger seat contains a mat that determines the presence and size of a seat occupant. This input to the airbag controller helps to determine if and how forcefully the passenger airbag should deploy in the event of a crash. The detection mat can develop cracks and fail. If this were to occur, the airbag would not deploy as expected, increasing the risk of personal injury. Dealers will repair the occupant detection mat to eliminate the possibility it may crack. Additionally certain vehicles will receive and extended warranty on the front passenger seat occupant detection mat.
Increased resistance at the electrical contact points may cause damage to the ground terminal and housing of the connector. This can result in an intermittent or permanent loss of one or more rear lamp functions (tail, brake, turn-signal, reverse). Intermittent light operation reduces the ability to warn other motorists of the driver's intentions, increasing the risk of a crash. Dealers will replace the rear lamp bulb carriers to correct this concern.
Vehicles equipped with an 8 or 12 cylinder turbocharged engine may overheat the circuit board for the auxiliary water pump. This could lead to smoldering of the pump or an engine compartment or vehicle fire. Dealers will replace the auxiliary water pump to correct this concern.
