Good luck.

Thanks for the link! I've read many threads on the subject, but somehow missed that one. I at least understand now that the 10K ohm resistor doesn't bypass the level reading, just the circuit's integrity check (I guess that is an accurate description)..

It appears from BMW Reimbursement Program Website that the Passive tank is covered in the extended warranty on my VIN (it was originally registered in a 'CARB State' (and still resides in a CARB state).

Now I have to decide whether I feel like gambling on what else will be wrong after the dealer monkey's get their hands on it..

Or if I want to try the PIXLFIX fix.. LOL!
