Bruce Nunnally Posted February 11, 2004 Report Share Posted February 11, 2004 Because we often read posts from people who need help with their cars, Readers often wonder if Cadillacs have an inordinate number of malodies. I mean, gosh, look at all these posts about fuel pressure regulators or what not. Here is a list of things to watch for on your 2000 BMW M5 for comparison, taken from a how-to-buy advice at http://www.m5board.com/vbulletin/showthread.php?t=38950 The used M5 buyer should consider the service and repair profile of the car, paying careful attention to MTBF of certain critical components, and other less critical but nonetheless aggravating ones that tend to break down at somewhat predictable times in the M5's service life. From the experiences of several friends who own MY2000 cars, and from consulting with the service advisor over a few drinks after work one evening, here are my conclusions on MY2000 cars: 1. The VANOS will go. It's not if, it's when. Probably at around 50-75K miles. If you are unlucky enough to be without warranty, plan on spending about $2-4K. 2. The clutch will go. It's not if, it's when. This is a well-known weak point on the M5. Driving styles and conditions can play into this. Better look for a car that has had a kind-hearted, skillful driver and a recent, documented clutch replacement. 3. The wheel bearings will go. It's not if, it's when. Another well-known weak point on E39's. Listen for odd vibrations coming (most often) from the front wheels when making a turn. 4. Rear sway bar brackets. Most of us are shocked at how inadequate the original brackets are. Not a difficult replacement. Potential disaster if ignored. Inspect them yourself and even better yet, look for an enthusiast owner who knew enough to have them replaced. When you find such a person, chances are most other issues with the car have been given proper attention. 5. Various irritating electronics problems will occur. There's no real mileage-related milestone pattern for this one. Personally, my A/C controller went down at 40K. Easy to fix, but quite uncomfortable if it goes during the summer months. Expensive (like everything else) if not covered under warranty. 6. (related to #5 above) Instrument cluster LED’s on many E39’s have been known to go out for no apparent reason. Segments of the message center display will simply disappear. Luckily, mine went out under warranty. I ended up getting the entire instrument array replaced with the newest version. Most M5 owners probably won’t replace this one if the cost is out-of-pocket. Better look for a used M5 that has already had this taken care of.
