2004 BMW 530i Problems

Fuel 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.

Mass Airflow Sensor (MAF) malfunctions

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.

Heavy rain causes water to collect on rear floor boards

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. One is that the sunroof drains can get clogged. The drains run down the c-pillars just behind the rear doors and if clogged the water backs up and runs down onto the floors. The other, more frequent issue is a torn or unglued noise baffle/vapor barrier that is in e...

The 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.

 

Brake 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.

Seat Back Side Bolster Heating Element May Be Damaged

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.

2004 BMW 530i Reviews

the front seat heating system keeps, overheating other than that I haven't had any major nor minor problems with it. the only down fault is that the vin number doesn't seem to show up in the American system, since I bought it while on active duty in Germany . I'm now retired and it was very hard for me to get any warranty work on it. nice car, very comfortable and reliable. I may had ...
Bought pre-owned in 2006 at 25K. LOVE this car. Have had only one mechanical issue with a minor oil leak. Other than this has been as reliable as my Honda, Acura, and Nissans of past. Very happy with the car, has 130K on it now, still looks like new but know it will start to cost more so am considering to sell it. East coast winters are tough. Don't buy the winter tires/rims at BMW dealer- go t...
2004 530i-transmission failure at 47k miles. Needs to be replaced to the tune of $5,200. No help from BMW or the dealer because the car is over 5 years old. We took very good care of the car with regular service at the dealer, and the car is like new. We never drove it more than 6,500 miles per year. 1,000 of that was our annual trip to Palm Desert. This transmission failure is so rare, th...
