I'm contemplating buying a used M5, that V10 is just glorious and I'd like to own one for a while. I've owned older BMW's, so I know to expect basically all the overcomplicated stuff in these cars to break, which is ok, I can fix it. My E92 335i was POS when it came to maintenance, but I kept it running great, it just needed 2-3 repairs a year after warranty, things like hoses, gaskets, bushings really don't last much longer than the warranty in modern BMW's.
Anyhow, does this high-strung V10 have any common weak points to look for? I'm having a hard time finding long term information. The car I'd be picking up would probably have in the vicinity of 80,000-100,000 miles on it. I'm also going to get the manual transmission, as I don't trust BMW's SMG one bit. I can rebuild a manual transmission no problem, they're simple.
Dear Friend, I own a 2008 M5 E60(6-speed) with about 114,000 miles here in California. My car has been at the dealer twice this month for some "big projects". The first one was for the throttle actuators which is common,...I had both of them changed along with reprogramming the car. This cost me $4,000. My second visit this month was for a new dual mass flywheel and clutch replacement. This was another $4,000. All I can say is that since I've owned this car, now 2 years, I've spent almost $14,000. Last year was a $3,000 tune-up which was spark plugs and new ignition coils. My car runs great now, but my wallet is a lot lighter now! I'm not even including new tires and cost for springs/install. All in all these cars need to be serviced or all sorts of performance issues can occur. Not to scare you, but I am an owner that likes to have my cars running correct at all times with zero issues. Along with maintenance and very careful oil changes, keep in mind that you might want to do some "mods"??? I've only had wheels painted gloss black and lowered the car with HR Sport Springs and it still turns heads. This is my second M5 in 6-speed Manuel and I love the performance. I feel that my previous E39 M5 handled a little better, but the newer M's are always better! Every once in a while I get people asking me if I want to sell my car, I just reply no never because I think there will NEVER be another V10 and I hope that this car commands a premium in a couple years like the M3's from the late 80's?!?!????

My experience has been rather pleasant with my 2007 6MT. Had it shipped to ohio from the west coast and now has 108,000 miles. In three years of ownership I have only had to change the alternator when it failed. I tend to all my own maintenance items and have been able to save cash in labor but parts are still a bit more expensive. She has been very reliable for me as a daily driver. No complaints
- Rod bearings are the number one catastrophic failure. If you own an S85, they are worn...period.
- Throttle actuators failures are quite common as well
- SMG PLCD clutch position sensor. $350 parts, 2-3 hours labor.
- SMG pump motor failure: around 60-80k usually, only need to replace the motor itself, about $350 in parts, 4-5 hours labor.
- SMG hydraulic unit wiring harness failures. Insulation degrades and shorts on sensor strip and actuator solenoid wiring.
- DSC hydraulic unit. Same cause as SMG, the motor is a DC brushed design and the brushes wear out. $400 to repair, 2-3 hours labor.
That's the most common by far, speaking from 10 year of familiarity, 15 rod bearing changes, 3 full engine rebuilds, 20ish throttle actuator replacements, countless SMG repairs, and salvage dismantling 26 S85 powered vehicles.
Yep, not buying one of these. Would rather get a E60 550i M-sport. LOL
