Hi guys/gals
my check engine light came on for a couple of min and now it comes on periodically. I checked the manual and it says it regulates emission from my engine. Any ideas please. I have 92 325is.
Thanks

It could be something as mundane as a loose gas cap or some other sensor firing off. Take it to a good service shop, a dealer or even some AutoZones and have it hooked up and get the fault code read. Then you can start to see what to fix and then reset the light. You can get your own code reader for $110-$150 and do that yourself as well as repair it.

my light has been OFF somewhere around 7 days i've owned the car, 7 or 9. its always on, like a night light, it brings me comfort.....

since i dont' have my own diagnostic i was going to have them run it at my dealership, but no, thats $120 just to run it. so i said "oh come on, i still get great mileage and great performacnce" and they guy said "yeah its probably just emissions, don't waste your money."

end of story.

1. turn off the car
2. turn the key to the "right before the car starts possition" the "on" possition
3. press the gas pedel all the way down 5 times
4. your engine light will flash in sequence's

Guys i just checked it out and it didnt work. It says you must have a motronic engine > 1.0 Mine says it has 3.1 so that should work at least i thought so but no. It doesnt work. No light comes on at all. Depress and release 5 times in rapid succesion i have done that. Any clues??????

I have a 92 325 and I used the self diagonistic for my car. I believe I got instuctions from this forum too. Anyway, the test worked and I was able to figure out what was wrong with it (purge valve). Remember to press the gas five times in relativey quick succession. good luck
