Re: CRD low power/high fuel consumption
Could be egr
Have you checked your oil level? When the high pressure fuel pump seal fails it will slowly leak into the crankcase and overfill the engine oil.
There is a fuel pressure sensor at the end of the fuel rail, if it is flacky it will allow different fuel, is that the one you replaced?
What is the condition of your air filter?
Last thing I can think of is a restricted exhaust, perhaps crimped or plugged.
