I have a 1988 BMW 325 I. Two things what fuse controls the heater motor. My box has no diagram nor does owners manual and Hayes repair manual. Second what grade of gas is supposed to be run in these machines. Thanks
Well here you go...2 diagrams for the E30 fuse box...they should be easy for you... * http://www.r3vlimited.com/board/showthread.php?t=60297 * http://bmwsport.net/component/option,com_smf/Itemid,206/topic,7.0/ The recommended fuel for the M20 engine is 92+ i mean 92(octane) and higher it will run good with 90...but you'll notice difference in the top end rpm so go for 92+...i hope i helped you mate.
