    What year and model of Z3 do you have? If it is VANOS-equipped (and it probably is), this could be an issue with the cam phasing mechanism.

    This is a 2000 Roadster 2.3, 2.5L engine.

    Yes, you definitely have VANOS cam phasing.

    It is pretty expensive to replace the VANOS system. I am not aware of any means to repair it, but perhaps there is a sensor related to it that can be replaced. You might have some luck googling, or heading to a BMW-specific discussion, to see what others have done when this type of error occurs -- any discussion of this code using a double VANOS equipped engine produced within 3-5 years of your 2000 is probably relevant.


    Odd personal note, the prospect of a VANOS repair for >$2,000 on my '95 M3 is why I sold it. However that car was running just fine, no codes, but VANOS was making a chattering noise. It was probably 6 months from serious issues. ;)
