Can anybody give step by step instructions on how to manually reset service lights on a 2006 M5. I just had my cabin filters replaced and the dealer didn't reset the service due light. It's a royal PITA to go back there....I have tried all the remedies that I could find, but none of them worked. Has anybody succesfully done this on their 2006 M5, as I think the remedies I tried were for other model years........Thanks.....Tom
