Sure you do. You just don't know you do. The Beisan seals are not BMW for instance. But that is compatible with the BMW engine. However the other non-BMW parts that you don't know you have may not be compatible. BMW parts usually are stamped with BMW part numbers and the bmw badge. It's quite easy to verify.

Which items would you be thinking of in particular? I've had this issue for about 4 months now, so I've gone through the common items that would cause the problems that I've been having, as you can see by the list above. Plus, I've stuck with only OEM items because I know that aftermarket ones can be faulty.

I wouldn't know. Why don't you go look at all the parts you put in and see which hasn't got a BMW badge ? You don't want OEM items, you want BMW items.

When I did my Vanos, has similiar mis-firing problem at idle. Codes said vaccuum leak but couldn't find it. Finally after CCV and new tubes, had to have smoke test down and discovered the leak in one of the spark plug holes - the gasket has gotten pinched during reassembly too small to see. I would never have found it on my own. Just something to consider.

I am certainly considering a smoke test to check for vacuum leaks. Where did you get it done and how much?

I meant BMW, I thought OEM has the same meaning. However, not all of the BMW parts have a BMW stamp on them. I bought an exhaust CPS sensor from Pelican Parts that is genuine BMW, and there is no badge on it. At first, I thought Pelican sent me the wrong part. It turns out that it was indeed Genuine BMW. Pelican states that "only BMW places the last 7 digits of the part on the item itself".

Does the part number match up with realOEM ? If I were you, I wouldn't mess with precision electronics from anywhere but the dealer. As you have already found out, the money you saved for not going to the dealer parts department had cost you inordinately more.

Actually the dealer price at Tischer is quite a bit cheaper than Pelican....$92 vs $127.

Not necessarily, because after all this troubleshooting & replacing parts the issue could very well be the VANOS unit itself and not the other parts I've changed. Although, you may be correct, its hard to say at this point
