2004 BMW 530i ProblemsFuel pump dies after 100,000 miles
The fuel pump gives out, and the car stumbles, idles very rough if at all. Giving it gas barely moves the car. Pump is located in the top of the fuel tank and the filter needs to be changed at the same time. Expect an $800+ repair bill for that alone.
The Mass Airflow Sensor (MAF) will die. It can stop working altogether, or the voltage output becomes unstable and out of range. Symptoms are varied from rough idle, lack of power, poor shifting, to preventing the car from running at all. Replacement is simple, diagnosis isn't always since it manifests in so many ways. The OEM part can run between $250 and $500 - should cost $50-100 in labor.
During a heavy or prolonged rain (or carwash) water collects on the rear interior floor boards. There appear to be two major causes for this - mine had the more frequent of the two.

2004 BMW 530i RecallsThe Positive Battery Cable Connection in the Trunk Can Overheat
The insulated connector for the positive battery cable may have been incorrectly attached to the trunk floor panel, which can lead to a loosening of the bolt connection. Loosening of the connection can cause an increase in electrical resistance and overheating of the cable connection, which could lead to a fire, even when the vehicle is not in use. As a precaution, owners are advised to park outside until the remedy has been completed. Dealers will secure the battery bolt cable connection as necessary to correct this concern.
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.
