2003 BMW 540i Problems
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.
A fluid leak may develop from one or more power steering hose. When a leak is being repaired, it is not uncommon for multiple hoses to be replaced.
The front thrust rod bushings—also referred to as tension strut bushings—are known to fail occasionally. The oil-filled rubber mounts weaken and crack over time, causing a mushy road feel and shuddering in the steering wheel when going over bumps. These worn bushings should be replaced.
