Hi ive got a 57 reg focus 1.6 diesel , i got a message saying engine fault , ive had it into a garage that does dpf's , they had it for afew days and checked the wiring and they said they got it down to the addative tank . They gave me a price and said to do it they rang the next day and said it would be 3-4 days to get the part . Its been 3 weeks now they just keep saying they are going to chase it up but dont seem to be getting anywhere , ive rang up 4 different garages to a price but not 1 rang me back . Are these bad jobs to do also are they ford only parts rang fords and they want £610 for the tank . Codes on car are p1922-60 , p1928-20 , p2585-21 , p2584-21, the tank got filled and reset so its not the problem.

The tank has no sensors in it so it is unaware of the level that is in there. Every time the fuel flap is opened it adds plus 1 to a counter and will inject a small amount into the fuel. When you reach a certain number it assumes the tank is empty.

Could be that there is a pump for this and that has failed, but I'm more inclined to say that your level wasn't reset properly.

Well just a update the garage rang me this morning to say they had the tank so to take the car to get it done , ive picked car up and its all sorted for now . £780 bill tank cost £620
