BMRBOI 8 Report post Posted March 13, 2008 (edited) Hey guys was doing some work under my 92 325i non vanos, cant find where the O2 sensor would be located. Im guessing upstream from the cat to the manifold? There is a plug by the gearbox, no O2 from factory? Sorry if im miles out on my guessing but i cnt find it. Cheers Edited March 13, 2008 by BMRBOI Quote Share this post Link to post Share on other sites

Your front pipe, from the manifold should go two into one to an elbow that opens up to two pipes again before the two cats. It should fit in that elbow. Does all the exhaust look standard ?? Have you had it scanned ?? This will tell you if its missing or not. It will come up as a fault code. If its not meant to have one it wont and a preset value will be visible in live data. Some early ones didnt have them Cheers Glenn Quote Share this post Link to post Share on other sites
BMRBOI 8 Report post Posted March 19, 2008 My engine has a two piece manifold which joins into one large cat. I still can’t see anything. Does that mean my car runs on map or just the airflow?
