2001 330Ci w/135K miles... My service engine soon light came on. I took the car to Autozone to have the code read. It came back with a lean condition in bank #2. The guy there told me that this code usually means one or more O2 sensors need replacing. Since BMW calls for O2 sensors to be replaced at 100K miles and mine are still the originals, I have no problem replacing them all and have already ordered them from Bavauto.com. However, the printout from AutoZone also lists MAF sensor as a possibility. Looking through the Bentley manual, there are codes specific for O2 sensors. My questions are: If the problem is really with the O2 sensors, why wouldn't the more specific code have come up? Would BMW shop's OBDII reader give a more specific code than a generic reader from AutoZone? Is there any other way to pinpoint exactly what the problem is when faced with a fairly vague reading? Again, based on the milage of the car and the lack of $$ put into fixing things so far, I have no issue shelling out the gappy to fix whatever, but on the flip side, I have no desire to spend my money unnecessarily either. Thanks!

Replying to: roadburner (Mar 10, 2008 2:09 pm) Initially I didn't put the two events together, but do you guys think that a missing oil cap could cause a lean condition? Something with the crankcase venting? I'm well beyond my automotive knowledge here and merely guessing... please be kind if I'm way off base!  Oh, btw, I'm not sure how yet, but I'm positive I will come up with a way to blame my wife for the missing filler cap.

Replying to: shipo (Mar 12, 2008 10:40 am) As for the wife, I will not blame her to her face since she'll know it's a lie and likely attack. I just need something to tell the guys so I can retain my ~cool~ factor.

Hello Guys! I have been reading all the posting on this site and I'm very happy that I joined in because it keeps me informed about my car. I have a 325xi '04 with 61,000+ miles on it, I owned the car now and It will be 4 yrs this may '08. I am aware that my 4 yr-service included with my purchase is already done. This is my dilemma, I went to one of the dealership 7 months ago for a regular maintenance/check up as per my indicator on my computer on the dashboard. So the service specialist told me that my car is due for a 14 pt inspection/check and I ask him how much it is, he told me it's going to be $750 for the check, I was a little shock and I just opted for a change oil. I needed an advice for my next service appt due approx. 6 months if I really needed the major inspection or I can just find a good mechanic to check my car. I am planning to keep my car and so far no major problem experienced! Thanks !!!

I have a 2001 325CI w/ 25K. Dealer diagnosed bad PCV & secondary pump light. Can't afford the $1500 the service dept wants to fix. I heard that you can "short out the light". My question: Anybody know how to "short-out" the lite or easy way to fix w/o taping over the light??
