How do I reset the service interval display on my 2000 BMW Z3. I have just changed my oil and need to reset. I found the data link on the console and have been told can be done by grounding the 7 pin for 3 seconds while the ignition switch is on. Will this work? Thanks!

I've found nothing to confirm that grounding 7 for 3 is a reset procedure.

Thanks for your help. I was hoping that I wouldn't need to purchase the relatively expensive reset tool.

Sorry, they do range around $100
**edit** but you can share the expense with others in similar vehicles...
