I just had mine done at mercedes.

3300 dollars in parts (at their cost)

they gave me a new turbo and full exaust for free


They also gave me a new ml to drive for a week until it was done.


THe car still does not run but that is another story.

She will fly as soon as I am done with it.

I am replacing the overboost sensor and swithover valves. all the rubber and plastic tubing

clean out the vacuum oriface on the vacuum pump.

And adust the throttle and transmission bowden cables. (have not finished yet as i am waiting for the parts)


Then the car should haul some diesel #$$


Also change out the fuel filters

The car you have was probalbly neglected like mine was. OTherwise the person would have gotten the trap oxidator fixed a long time ago.

good luck

email me if you need any help
