1998 BMW 540i Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 1998 BMW 540i


Engine oil leaks commonly develop from both valve cover gaskets, intake manifold, and PCV plate after about 60,000 miles.

Leaks are known to develop in the cooling system. It is common to see more than one part recommended for repair/replacement due to overlapping labor and the use of many plastic parts in the system.

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.
