20 Most Recent 1987 BMW 3 Series Questions & Answers

Hi Troy,
It's been a while since I have reset the SI lights on an E30 but there is a way you can reset the lights on your own. Located near the intake manifold you will find the small round diagnostic connector. It is a little larger than a quarter in size and will have a group of female wire terminals inside. The shape reminds me of PAC-MAN. You can use a test light for the reset. Clamp the test light to ground and insert the probe into the inner most pin of the Pac-Man. (<-) Only leave this grounded for approximately 7 Seconds. If it doesn't reset the first time, you made need to do it twice. If it does not reset you can usually purchase the reset tool online for about $20.00.

Have you checked the bulbs and the fuses? If not, start there.

Check your fuse and the fuel pump relay.

Usually it is a sticking throttle plate, vac leak, or a problem with the idle control valve.

Maybe something as simple as a fouled plug. Have you checked spark plugs? Wires? It's a process of elimination...

belts should be changed every 60,000 miles or 5 years max so it is due a belt anyway.
if the belt does come apart it will do serious damage to the valves , head and pistons.

i would change the water pump at the same time for peace of mind. especially as it will be exposed while doing the belt, and you do not know if the pump is seized/worn.
