Does anyone know if there is a way to reset the check engine light in a 1986 bmw 325E without using a ob1 tool or without taking it to the dealership to get it reset? In my Mazda if I pull the battery out for about 5 mins then the engine light clears. I just need to get this done so I can pass a safety inspection because I heard if the check engine light is on they will not pass you. Does anyone know if this is true or not? Let me know if you guys have the answers.

Disconnect your battery for 10 minutes, that should do the trick.

to reset the 'check' light just hit the 'check' button on the checkpanel which is located at the front center of the cabin ceiling. you'll have to do this everytime you start the car; however, the check light is not the check engine light and by fixing the indicated problem on the checkpanel the light will turn off automatically once you start the car and hit the brake pedal.

yes. but that is not the check engine light. it will blink if you have low washer fluid, low oil, burnt out brake light, etc.

you can always turn it off once you start the car by hitting the check button.

Alright man, I figured out what you were saying. also you wouldnt know how to reset the inspection light underneath the gauges where it lights up, supposidly when I had it in the shop for not starting, that was not reset after they fixed the problem, I mean its no big deal but I just am trying to keep the car in good condition and running well.

this is what I do. Theres a diagnostic socket at the left front of the engine. I take a jumper wire, put it on pin 7 (or 8, or 9), and to ground. Turn the key to KLR (first position), and it will reset.

the left, like from where your sitting in the drivers seat? That sounds confusing though. is that shown anywhere in the haynes repair manual where its located or do you know the exact name or something it is next to on the engine itself.

yes. the left (drivers) side. It's not shown in any manuals. It's a trick of mine. I think it's pin 8 to ground. But it might be, 7 and 9. I'm just telling you what I do, not what I recommend.
