    The most common problems could be spark plugs- coil pack - dirty throttle body - dirty air filter - dirty mas air flow sensor- clogged fuel filter

    Leaking injector copper washer is usually what does this on mercedes diesels. On OM646 EVO 170HP this is quite common to happen even before the actual tar is formed arround a leaking injector. Get it replaced fast before it damages the fuel return and injector wires

      Bro could you expound a bit more if it was explained in layman terms, my car is driven 72 kms and i changed the engine mounts a months ago which were damaged but did not solve this issue. My car is a w212 e220 cdi which is a 170bhp car as stated in your comment, how to go about this?

    I have the CLA Shooting brake 220d and it intermittently does this when im just cruising at a steady speed. It almost feels like it wants to stop when im driving and you feel like youre being pulled back but then it settles. By this time, i find out that my paddle shifters no longer work and i think the car goes into into limp mode. Switching the car off and on again resets everything and works fine, well until the next time it does it again. Its intermittent but can be reproduced pretty much every day. Is there anything i could just replace to see if it fixes it? The car has only done 65k.

    There is a long list of what could cause these but most commonly are a leaking injector, bad fuel pressure sensor/regulator or a vaccum leak. Hope this helps!

    I had the same problem with my mb 220 cdi 2008 ..my friend advise me to run in the high way and drive crazy..Kik dawn and so for 30 minutes..and it’s work like a magic.......I drive usually really slow in boring way...
    So if you drive in the city usually the car need to run fast for some time and press the gas to the max for 3 to 4 time..

      for those of you who are still confused about the RPM going up and down, it can be from a dirty MAF sensor immediately cleaned with a special MAF liquid..
      if it's clean and still going up and down, don't panic.
      try the next step.
      .you buy a new fuel pressure regulator, install it and feel the difference. it's located near the injector. do not forget to unplug the petrol fuse in the rear trunk.

      I encountered the same problem on my C220 CDI (see my channel) it was 3 faulty injectors 4. After change no problem. Try to see with a Mercedes garage if there is not an update available for the caluculator, this can help.
