Hello, since about half a year it happens sometimes that the engine “turns” a bit. The strange thing is that the engine then runs again perfectly and quietly. The FOH could not read out any error and since it stayed so far with the “from time to time a little jerking” and I did not want to start unnecessarily on suspicion to have parts replaced I have done nothing further so far. Unfortunately the last weeks now this jerking occurred more and more often and it came “from time to time” (scho The engine can then be started again without any problems but is still stupid and also a bit dangerous (Servo, braking force etc.). Also in idle mode with automatic position on “N” the run is very restless. When accelerating the engine reacts also very “delayed”. Now I had my 200,000 he customer service and got the following result from the workshop: “Pile in the fuel, pump renew, The workshop master told me following my request: “Probably parts of the coating (gold-colored particles in the fuel) of the high-pressure diesel pump dissolve and cause these disturbances”. Has anyone ever heard of something similar!! Lt. FOH would cost the repair (new pump and fuel system clean) approx. 1,500 to 2.00 €!
