I have spent a month looking for this with no luck...
Try a bentley manual. I guess it could not have the "240d" specifically. A parts sight may have an exploded diagram.
email me at jacks1456@yahoo.com and I will try to send you the schematic
The oil capacity of a 1980 Mercedes 240d is 5 quarts. This include the oil needed to fill the oil filter.
How do you change the headlight on a 240D mercedes?
Mercedes 240D.
The fuel pump on a 1982 Mercedes 240D is located inside the fuel tank. A replacement fuel pump can be purchased at any auto parts store.
On my 82 280D I found the Sun roof leaked. ater resealing in. no more water.
The radio the 1977 240D is equipped with does not require a radio code. If you have an aftermarket radio, you will need to contact the manfucaturer.
Unscrew them , & repalce , usually only the nozzle is replaced .
It would be cheaper and easier to get a td engine and drop it in.
remove wiring, unbolt from block. reverse process for new starter.
Replace the O-ring on the injector.
