Started getting this message on my 1.6 HDI DPF 110 followed by an 'Antipollution faulty message' (MIL now permanently on) so I changed the fuel filter but could not prime the system from the rubber bulb so had to suck fuel through with a hand vacuum pump at the return connection. Car drives OK for 3-5 miles from cold but then hangs back (misfire?) at more than approx. 1/4 throttle. Could this message mean that the fuel additve tank is empty or is there another message for that, or what? Can't help with fault codes as my OTC scanner will not communicate with the car.
