I havehad a long list of problems on in my 2006 Focus
Initiallythe turbo had went, this was fixed with a new cartridge and variable vane unit,
and working well
Power had went after a day or so, this was traced to be a problem with the Air Flow
Metre, this was again replaced and working well
I drove the car for 5miles and then the car got a error 'Engine Systems Fault' and down in power after pluggingthe car into the laptop it is pointing the error to be the Diesel Particle Filter
I attempted to perform a drive to regenerate the DPF, after 30mins with no joy I packed it in, in a previous car a error light in the dash idicated when the DPF was operating correctly.
Any idea ?
