If not I would look elsewhere.

Please ignore if this has already been done. It's been a few since I read the entire thread and I can't recall all the diagnostic work that's been done.
Yes getting P0344 on my 01 3.0. gap won't leak air since it is very tight with the o ring, the body of the sensor is not perfectly co-axial with the opening in the head. We're talking MAYBE a degree. Check out the picture above.
Thanks for the help!

If you've checked the fitment then I doubt it's the gap. At this point if you still suspect the CPS then buying an OEM part may be your next step. Or, as others have advised, taking it to a shop. I'm not sure how much an OEM CPS costs but if it's not too much then what would be the harm? The worst is you've spent money for something that didn't solve the problem. But now you've got a spare :D Or maybe you can resell it to someone. From what I've read over the past few months this is a regular service part which people seem to need.

yup my same thoughts exactly. I already ordered an OEM BMW cps for 90 bucks. The ebay one was 31 bucks so not like Im getting screwed here. Well let you all know the outcome this thursday or friday!

I did the same with a MAF. I ended up paying $120 for an aftermarket one. It ended up solving the problem for a few weeks and then the vehicle began to exhibit MAF problems. I borrowed an OEM MAF from my mechanic and drove the vehicle for a couple of weeks. The problem was gone and I just paid for the part.

Ok I missed a bit apparently as I was on a short overnight vacation/trip, but it sounds like the cheap ebay sensor was causing problems and it should actually be fixed with the OEM part now ordered.

Looking back at the pics, it kinda looks like the housing is warped on the ebay sensor causing the gap/not letting it sit flush.

OK update: replaced Ebay sensor with OEM sensor from bavauto... problems are completely gone, codes are gone, runs better than ever! The moral of the story- cheaper is not always better...

Congratulations on solving the problem. I learned the same lesson with my MAF.

Congratulations! Question: Did the gap that you had with the old sensor disappear as well?

Nope, that gap was exactly the same with the OEM sensor. So that wasn't the problem.
