Mercedes E280 96P - blackdog
After carrying out a 95K service (last august) the engine seemed to be 'missing' Franchised dealer carried out some repairs Foc but would only say that they replaced a top end of a tappit.

They have just returned it and on trying to run the revs up a bit it starts banging and belching smoke at 400rpm. Mr Merc says that it cant be reved whilst stationary as the management system cuts out as it dousn't sense any speed.

As you can tell I am not mech. minded, so are they telling me porkies? Can anyone help please?

Yes I think they are. I have never heard of this. Even if there was such a control device it would not cause the engine to bang and belch smoke! You need to find out more.
