Hey all, still chasing this bloody air ingress following worsening breakdowns.
Mk6 2.0 tddi, I can only pressume, getting air in somewhere in the fuel system, emptying my filter slowly.
The story goes -
Relevant or not, i put a half bottle of redex into a full tank 30 minutes before this all started. Driving along, lost power and chuffed white smoke, pulled over and it was dead. Recovered home, fuel filter drain hissed and dribbled out shite, switched for a new filter, topped up, ran, beauty. 2 days later, died (no smoke, just dead, flashing coil light), diesel filter was empty, filled, ran, 2 days, dead. Figured an air leak. With my head under the bonnest i thought i could hear a hiss when it was turned off from the injectors, changed the leak off pipes, still getting air in, changed the fuel filter housing (genuine ford), went for a drive, topped it up, went for a drive, 15 minutes in and low and behold, loss of power, still idling (just) with white smoke chugging out, limped and dead. Filter empty, topped up, turned over a over, needed a squirt of easy start (i know, but needs must), clatter from the pump as it was obviously dry but eventually kicked into life, drove 5 minutes, dead again. Recovered home.
No visible leaking from any connections, no signs of leaking from pump, can I hear a hiss around the brand new filter housing, maybe? Very hard to tell.
Still air?
Failing pump?
Injectors letting in air?
Fuel line o rings?(anyone got a size for them?)
I should add, the little pressure/service indicator gets dragged down into the red when it runs out of fuel in the filter, is this normal?
Thank you to anyone that can shed some light on it.
