1994 BMW 540i Problems
Multiple Parts May be Recommended to Correct Coolant Loss
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.
Loosness in the Front Suspension Due to Worn Tension Strut Bushings
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.
Vibration Evident in Drive Train
Bought car and drive train seemed to vibrate excessively when switching to fifth gear (automatic). Changed guibo and carrier bearing and during process (which were fine) and noticed that transmission mounts were sheared off where mount bolt passed through transmission. Replaced mounts and problem was eliminated.
Engine Oil Leaks
Engine oil leaks commonly develop from both valve cover gaskets, intake manifold, and PCV plate after about 60,000 miles.
Loss of Power Steering Fluid Due to Leaking Hoses
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.
