I had a 1986 300D that rusted out from underneath me but I recently bought a 240D with no rust and it appears to run wonderfully. I at last have time and money to do some work myself. I am wondering which of the many maintenance manuals to buy. I do not intend to do any major engine or drive train work. Mostly interior, electrical, perhaps injector replacement if that is something a mildly talented amature can handle. An immediate repair needed is the replacement of the diesel fuel line, fuel level sensor and dash clock. What book(s) are best?
