Hi i have a 07 multipla that has had the engine rebuilt after cam belt snapped due to water pump failure. Since then the engine control error comes up and light stays on dashboard. I have had the error check and been advised that the fault is with the DPF but the DPF light does not come on. I have taken the car for a run down the motorway but the engine is still limited to 3000 rpm. Can anyone advise what i could look at?
