Thanks for thoughts. The O2 sensors are pretty new, pre cats changed 1.5 years ago. If sensor was bad that would be a different code wouldn't it?
Tried to listen this AM closely to cold start, couldn't really tell if pump was working.
Doru, how difficult was access to the valve?
I LIKE OLDER BMWS, PLEASE HELP ME
