E36General discussion and technical help for (E36) 1992-1999 3 series cars. 318, 323, 325, 328.
Oh, and I can't get that stupid 5 stomp method to work. Any tips?
Get in the car, shut the door. Put key in, and turn to position 2. Press gas all the way down to the floor and back up, take your foot off momentarily, then repeat 4 more times. Do it deliberately and don't try to rush it- you'll have plenty of time to 'stomp' it 5 times within 5 seconds. It's an art you'll have to master, but trust me, it works. It's not a trick, it's the official way of getting the codes on OBD I.
Fault codes will often remain stored even when the CEL is not lit. All the speculation you do won't get you any closer to solving the problem if you don't eliminate the possibility that the answer may be in the OBD . . if the CEL lights up, that's the first thing you need to do, otherwise you're just gonna make yourself crazy with all the suggestions turning into one big convoluted mess
Called BavAuto, Al said it was the oxygen sensor relay.
Apparently, the "Lambda" is the oxygen sensor and the "Lambda Control" is the oxygen sensor relay. He said that it could be that the O2 sensor isn't being told to warm up properly and that the cause of that could be the relay, as in code 1222.
Any suggestions on parts? Part numbers?

Bingo! That was one of my guesses Yea the O2 sensor is aka the lambda sensor; that's what it's known as in Europe. Here's the thing: I think Al is wrong. "Lambda" and "Lambda Control" both mean the same, and have no reference to the relay. His diagnosis should trigger a code 1264: O2 sensor heater malfunction. That will usually indicate that the relay is faulty. A code 1222 however, indicates the sensor is operating beyond its normal range. You can verify this with anyplace that lists the OBD I code system, whether it be the Bentley, Pelican, Unnofficial BMW, etc. But to be on the safe side, I would replace both. You'll be able to get the O2 sensor from Pep Boys or anyone online that caters to BMW's. The relay you want is the Bosch orange relay, Pelican's part # is 61-36-1-378-238-M14.
