Resetting Inspection Lights

The Inspection Lights, also known as the Service Indicators, are a series of lights on your dash cluster to tell you when it's time to service your E30. There are three lights in total; Inspection, Oil and Service.

If you service your car yourself, you don't want these angry red lights glowing at you all the time making you feel guilty, so here's how to reset them back to green.

Procedure

Resetting is done via the Diagnostic plug in the engine bay. All you have to do is connect two of the terminals with a piece of wire; a paperclip will do.

Identify pin 7 in your diagnostic plug. Facelift and Pre-facelift cars have different plugs, so use the diagnostic plug page to help you.

With ignition off, connect pin 7 to ground using a paperclip or short piece of wire. Ground can be one of the other diagnostic plug pins (pin 1 on all models, also pin 19 on facelift cars).

With the wire in place, turn the ignition on for 5-10 seconds. Turn off, and remove the wire.

Repeat this procedure to reset the Oil inspection light and service lights.
