Known problems with Z4m?

TexAg06 · 01-06-2010, 12:31 PM

I absolutely love the Z coupe especially the M version. What are some known problems that nearly every car (significant percentage) ends up getting? Like with the N54 engine on the 335, 135, etc., you will have high pressure fuel pump problems. Is there anything like that with the S54?

Just an annoying clutch delay valve.
Most of the issues with the engine were worked out over the E46 M3 life cycle.

Some basic info here for you http://www.z4-forum.com/forum/viewtopic.php?f=2&t=15177

but i'd especially like to note the O2 sensor fault. I've had mine for about 2 months (bought it used and the car was at around 28,000 miles at the time) before i had to change 3 faulty ones out of the 4 on the car. I ended up replacing all four just in case though. I've read of others that had them go twice on them already.

My car has 40,xxxkms on it and ive had it for over a year now.
Now problems to report - tiny leak in power steering line which was replaced under warranty. Its been the easiest car to own.
