O2 Sensor Removal/installation

[napalm]

I read the articles through the DIY link for Bimmers.

The O2 Sensor on my 325i Convertible is more on the top side of the exhaust near the middle of the car.

I had to remove my exhaust to properly seat a socket onto the old O2 Sensor (which required me to cut the wires off).

The website does suggest using a 'slotted' socket, which I've never even seen. The website does list some complications removing the BMW Ti versions. I would also include this 325i Convertible in the same difficulty rating.

So now its replaced, whats the proper way to reset the Engine light? Remove the negative terminal on the battery? What is the proper waiting time ?

Thanks in advance!

check the faq forum there is a DIY for the rest, that is if your car is obd1 i believe. as for the O2 ,sounds like it took too much work to get that thing done, was the new O2 with a harness or did you have to splice the wires?

No I was relatively impressed. The O2 Sensor came with a slightly longer than necessary harness, but it directly plugged in. The part cost me $65.00 new.

I wonder what it cost to have this done at BMW, anyone out there have it done?

The correct way to reset the engine light is to use the tool that plugs into the diagnostic port but i don't think everyone has that readily available.

Simplest way is to disconnect the negative terminal, wait a few minutes then secure it back down. It will erase any radio memory or any other electrical components on your car that need constant power, but it sure as heck beats going to the dealer and paying for it to be reset.

I checked back on the DIY forum post. The tool isn't necessary from what I understand (Not sure what years it is important). OBD1 its simply a wire grounded to the specific pin in the diagnostics plug (pin 7?). Then there is different time allocations per service light. My light reset with 12 seconds of grounded pin 7 (ignition in the second key turn -unstarted).

My light went off by itself after about 10 minutes of driving (OBD I).
