I posted for another thread in the e39 forum about possible VANOS issues. It turned out to be one of two VANOS control solenoids. But I only found this out after replacing one set of cam position sensors. I am replacing both solenoids, even though one is functional.
As a result, I have 1 set of cam position sensors (exhaust and intake), and 1 VANOS solenoid unit that will be sitting in my garage in about a week or so (the new parts are special order, so they won't arrive until next week).
They are off of my MY00 M5 with 60k miles. If you are interested in them, please let me know....any reasonable offer will be considered. The new ones are quite expensive, and not readily available...so hopefully I'll be able to help you out.
email me at
cvp911t@hotmail.com if interested...I'll post when sold.
Thanks,
Lance
