1998 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.

Purchased it in July 2011, 74000 miles on it. the alternator, power steering pump, both serpentine belts and supply hose to the power steering pump were all bad. I opted to put on new rotors and brake pads. Changed to high speed tires (had 112 MPH on it) now has 168 MPH. Had both rear window corner screens dangling took them apart and fixed them. Lots of little things needed attention, trunk tool box hold up screw was broken, head light adjustment on both lights were broken (replaced with projectors). Last things to fix are the wheel well liners are shattered, brittle plastic or something. There is a little bit of shake when slowing from 70 in the front end acts like a warped rotor, but is intermittent. Now that it is all done driving it as compared to my Mercedes SLK is so much better, it out accelerates and out handles that car hands down. It is quiet, sure footed and comfortable. The sport seats make this a great long distance driver. Anyone with a modest budget and some mechanical knowledge would appreciate the simplicity of the car but know the upkeep of it is a little more involved than your typical chevy or ford. Bottom line, this is a drivers car, it is very fast, and handles extremely well, predictable handling makes even a novice feel like a accomplished driver. When I was a kid working on my first 55 chevy this is what I wanted it to work like. Awesome car......
Problems with front end suspension
AC has never worked properly
Absolute blast to drive. 123k on it, no major problems. Still smokes all them mustangs/camero's/etc... Nothing like merging onto a highway at 120 mpg with two finger on the wheel - LOVE IT.
