2003 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 bushingsalso referred to as tension strut bushingsare 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.

Engine Oil Leaks

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

based on 1 customer reviews
The car ran beautifully for 7 years (2003-2010) ..Then everything fell apart at 85,000 miles..... radiator, water pump, power steering, hoses/belts. "Service engine soon" light - Recommendation: Sell car at 75,000 miles - and don't look back.
