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!
