2004 BMW 525i Problems

Burning Smell or Oil Drips on the Ground Due to Engine Oil Leak

Valve cover gasket leaks are common after 60,000 miles. Symptoms will include oil drips under the vehicle and burning oil smell from the engine compartment.

New 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.

Coolant Leak From Radiator

It is not uncommon for the radiator to develop a coolant leak. A leaking radiator will require replacement. When a leaking radiator is replaced the entire cooling system should be inspected and if any additional leaks are found they should be repaired also.

Overheating can cause severe engine damage. If the engine begins to overheat it is recommended to stop at the first available location and have your vehicle towed to a repair shop.

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 525i Reviews

I love my car. It is a 2004 525i. I just put M6 take offs on it and it runs perfect. until i recieved the transmission error on the dash. Do i need a whole transmission? BMW said that they would beglad to help at a tune of 6500.00. Any other solution to look at first?
trouble free and an outstanding "driving machine." My next car will be a bmw...Joe Lucas
This car is very reliable, I purchased it new in June 2005. The body style is still the same in 2010, so most cannot tell the difference between my 2004, and a 2010. My 525i is a great value. If you check newspapers and car lots, you will rairly see one for sale. They're keepers.
