View Full Version : E30 - Resetting service indicator lights?

11-25-2002, 12:44 PM
My friend got an 1986 E30 325i and we need to reset the service lights. I read we short out pin 7, but can somebody give me some more help on this because it isn't working. What in the engine would work as a good ground that's close by the data connector?Or do I need to touch the frame of the car (meaning use something other than a paperclip because of length =/)

let me double check I know my car its 7 and 14 pins 14 is the ground you turn the car to acc power spot wait till the light resets make sure as soon as it resets you turn it off or you will change the lights the oil light will be the service light and the service light will be the oil light I ve done it 3 times now and had no problems let me double check for your year. b.r.b

yea pin 7 is the reset light im positive about it. like I said make sure your ground is good and watch the light as soon as it resets turn the key off. it takes about 3-5 secs for oil reset and 7-10 for service reset
