    Bought a Certified Pre-Owned 545i two years ago and have just developed a rough idle problem at 42k miles. First visit to the dealer resulted in replacement of cylinder #1 ignition coil, however, this did not solve the issue.

    Returned to dealer and they assigned my problem to a chief service tech who acknowledged the problem and feels that it is most likely a worn shaft that controls the opening duration of the intake valves. Chief tech advised that this has become a problem with this model and year, and that BMW is aware of this issue.

    Only other prior problem was a fuel tank pressurization pump failure. Also, have sensed the car jumps a little after putting transmission in drive. Otherwise a terrific car!

    Any thoughts or input would be greatly appreciated!

    I have seen that issue discussed on other forums. However, I have not had that problem. I have a 2005 545i with 76,000 miles and it idles smoothly.
    You might want to check some of the forums for more information.
    Good Luck.
