How do you reset the service indicator lights on an E34 1995 BMW 525i Touring?

You can buy a proper tool that will reset service lights and inspection light giving you all the green lights from Ebay price £12:99 plus p/p realy simple tool to use, cuts out all the guess work, and getting the right connector. I have been using mine not just on my 525 but it will also do 92 -2000 models even carged my mates £5:00 a time, tool has paid for it self over and over time and time again. Just go in to Ebay motors car accessories and enter reset tool for BMW. Money well spent.
