Since this IS an E32 735i...I believe you mean that you want to reset your Service Interval Lights...which is something different than your OBC (OnBoard Computer).

You should find the info on resetting the SI lights at www.e38.org/e32 (add the "/e32" to go to the e32 specific help page. ;) Do a page search [Ctrl+F] and use "Oil" as your key word to search for...you should find a couple of links with write-ups on how to reset them.

This is the Service Interval Light (w/Oil Insp illuminated)
