does anyone know where i can find a service manual for a 1991 318i. none of the manuals i have seen include the 91, the Haynes manuals are from like 85-86 and the Bently says it excludes 91 318i for some reason. i have even went directly to my local BMW dealership and they do not sell service manuals. if anyone knows where i can find one it would be greatly appreciated. i am specifically looking for fuel system wiring diagrams. i even have Alldata and Mitchell on demand subscriptions and it is IMPOSSIBLE to find a wiring diagram for any engine controls on my car. let alone just an all around good service manual. please help!
