2003 BMW 525i Problems

Blower Final Stage Fan Resistor May Fail

The blower final stage fan resistor is known to fail. Symptoms are the heater fan speed varies regardless of the setting, the fan will not turn off when the car is switched off, or the fan will not switch on at all.

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.

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.

2003 BMW 525i Reviews

seat problems. pulley. clutch fan. head lights bulb. I can go on and on
Great car but repairs are expensive. The question is there is no replacement available for it. Find a good independent repair shop as BMW of North America and ALL dealers are a complete joke!! If you find a good repair shop this is a once in a life time car. Around 94595 I would highly recommend European Werkstaat. I would buy it again.
I bought my 525i used from a co-worker with 71,000 miles 4 years ago- I now have 146,000 miles and other than normal maintenance, it is a terrific car and I am happy to have it!
