2004 BMW 545i ProblemsNew Brake Pad Wear Sensor Design Will Prevent Squealing
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.
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.

2004 BMW 545i RecallsBrake Vacuum Pump Leaks Oil
The brake system vacuum pump check valve can leak oil and contaminate the power brake booster. This can result in loss of power brake assist. Dealers will repair the vehicle as necessary free of charge to resolve concerns.
Excessive wear may develop on the side bolsters of the seat backrest. As a result, the seat heater mat located in this area may be damaged. If such damage were to occur, with the system turned on, the occupant may feel excessive heat from the area. The heating element may damage or melt a small hole in this damaged area of the seat cover. If this happened, it could lead to the seat occupant being burned. Dealers will modify the seat heating circuit to correct this concern. This recall is expected to begin during December of 2004.
The digital management control (EMC) unit may not have been produced according to specification. The engine may stall and not restart. As a result, a loss of power steering, and after repeated actuation of the brake pedal, a loss of brake power assist will occur. These conditions could result in a vehicle crash. Dealers will install a new (EMC) unit to correct this issue. This recall began on July 16, 2004.
