325 oil service reset

As I am working through things on the 325 I came across the oil service gauge on the cluster. I changed the oil on Sunday night (it really needed it), but the gauge still showed that it was bad. There is a tool that cost about $70 that will reset it, or you can go to a shop and they'll do it for $25 or more. Or as I found on one website you can easily reset it yourself in a few minutes. Actually seconds. Tools required - a paper clip or piece of wire. I have copper wire laying around from having to run wiring in the 02 so I took a small piece, striped the ends of it and went out to the car. The procedure is this, put the ignition into position II (just before start) so that the dash lights come on. Pop the hood and go to the front of the car, open hood. Look to the passenger side of the engine bay and right behind the left strut tower there is a circle thing. Unscrew the cap and look for pin 7 and 19. They are labeled. Stick one end of the wire or metal piece in 7 and then the other end in 19. Hold it there for about 4 to 5 seconds. It took me a couple of times. Don't go too long though. Once the time as elapsed pull out the wire. Now go check the dash, you should see all green on the oil indicator.
