Initially, general information to be able to perform my own maintenance such as filter replacement, fluid replacement, torque values and so forth. I have owned an E32 BMW for the last six years and performed all the maintenance work myself. This included the normal items plus other not so regular parts like fuel pump, radiator, water pump, driveshaft, suspension components, cylinder head gasket, and A/C retrofit. The list sounds horrendous but these are typical "consumables" on an E32. I just want enough information to be able to diagnose and repair problems without having to drive to the dealer every time.
