How do you reset the oil service light manually on a 2003 BMW 325i E46?

Answer 1

The only way I have found so far is to buy a service reset tool. Go to http://www.bavauto.com/se1.asp?dept_id=375 and you can buy one with a built in code reader as well. I would imagine there is a way to do it without the tool, but I have not discovered it as yet. edit by copteaser: There is a manual way and it's farely easy.

the source of my info you can find at the following urls:

If your OBC needs to be reset after completing your oil change, there are two ways. NOTE: If you miss a step, just turn the key back off and try again:

A. Model Year 1999 to Mid-2000: You should have the older round 20-pin DLC connector under your hood behind the battery terminal, you need to use a small length of wire to connect (short) pins 7 and 19 for 3-5 seconds with the ignition key in position 1 (Accessory).

B. After Mid-2000: You should not have the 20-pin DLC connector. You only need to hold the left odometer reset button while turning the key to position 1 (Accessory). Keep holding the button for 5 or so seconds until any of the following shows in the display: OIL SERVICE or INSPECTION with RESET or RE. Release the button and press it again for another 5 or so seconds until RESET or RE flash. While the display flashes, press the button one more time briefly. If done correctly, END SIA should show up for a few seconds. All done.
