There are aftermarket cruise controls (in Europe sold by Waeco) which can be installed on your car. It can even be made to work with the original MB cruise control handle.

Or you buy the original stuff. New it is very expensive. If you buy it second-hand, the electronics might not work properly.

The following items need to be installed:
- speed pickup sensor (on the driveshaft)
- shut offs switches for the clutch and brake pedals
- actuator in the engine bay which works the gas linkage
- on/off/resume/coast/accelerate switch (which can be the original MB handle, but can also be aftermarket).

and the wiring to the electronic control unit from and to all those components.

Here is a link to the Waeco cruise controls:

WAECO mobile solutions - Cruise controls

They come with the parts and the wiring instructions. I don't know whether that is available in Canada, but there must be sets like that, or it is available under a different name.

Govert: This is a good discussion. Fixing my cruise control is high on my priority list for my 1981 240D (4 Spd Manual). It has all the cruise control components installed. The cable from the actuator seems to have been cut. Any ideas why someone would cut this cable? I guess it is possible that it broke, but everything else in the engine compartment is fine. What would be the first thing you would check?

Do you have this type of actuator?



That is vacuum controlled, which can leak and not function properly anymore.

The original electronic control unit can have some troubles too after 30 years (sometimes resoldering and refitting capacitors gives it a second life).

That's the one! That is exactly what I have. The cable that comes off the end and goes to the throttle linkage is a 'Bowden' cable. It is broken/cut from the linkage. Will this type of cruise control also have a control module? If so, do you think I should replace the actuator first, then work on the control module as needed? I am also pretty sure I need to replace the switch on the steering column since it seems difficult to operate. Might be corroded contacts inside.

You can repair the original system using the FSM:
54 Chassis Electrical, Instruments
Select the Cruise Control Pneumatic.
It has a electronic control unit.

What things needs to be repaired first is difficult to say. You can connect the bowden cable and see if it works at all (try it on an empty road) and use the tests described in the FSM to see what is the problem.

...or you can install an aftermarket system.
