2000 BMW 740iL Problems

Humming Noise from fuel tank

Not only when I started the car did I heard a humming noise coming from the gas tank, it happened fairly often while driving - more during accelerating. Had the fuel pump changed, stopped most of the humming noise but still get a much lower level humming noise off & on quite often - What did I need to do now?

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.

Engine Oil Leaks

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

2000 BMW 740iL Reviews

I really like this car. I have owned it for 2 years and while it has not been trouble free, I have a good BMW mechanic and I order my own parts from ebay and the cost to maintain the car hasn't been to bad. I get 18-25 MPG, the car runs so smooth that I have had people put their hand on the running engine and swear they couldn't feel it. I have replaced all the normal wear items, Battery, plugs...
BMW stands for Bust My Wallet!
Worst car we have ever owned. I have 20 year old Porsches that I drive daily that are more reliable than this POS.
