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?

Should you be interested I have a Service Manual for Engines 615, 616, 617.91 which I would be willing to sell. I had a 1983 240D that I sold a few years ago. The manual is published by Mercedes-Benz of North America, Inc. It was printed in 1982; these manual have not been available from Mercedes for many years.

Between my family and myself I maintained over 800,000 miles worth of diesel 123's with nothing more than a Haynes manual. The particular Haynes for this model is QUITE good.

Mine is quite greasy and tattered now, but it certainly has redeemed the $20 or so that I paid for it.

Good luck,
