Yes, it's fixed now. 20 days no issues, cannot reproduce the problem. I am so happy.
The old pump was working but not to its full function. I guess
I doubted it would be the root cause but had no other clues at this point so spent the $400 to get a new one and replaced it and ow it fixed the issue.

Since you owned the car, you've never had this issue prior correct until recently correct? Where do you store your car normally? I Definately respect your proactiveness in figuring it out especially on your own, props to you!

Thank you, man
I park it in my garage, which is warmish and dry. first time this issue happened was Feb this year. It's been a roller coaster the last few months.

Enjoy your Fully operational car! and we are always here to help! I truly enjoy to help others with whatever Knowledge I know, and can relate to previous experiences, and pass it on, because these BMWs are amazing machines! How's your Winter? over here its been the driest as in No snow since I've lived here in the Great Basin.

Sorry if I missed it but what code did you get to make you change the CPS?

Thanks.

Thanks.

No codes for that. I was doing online research and it was one of the items someone suggested, the sensors are pretty cheap and easy to change
