    2001 Audi A3 1.9 tdi. I'm new to diesels so apologies if this is a silly question. I'm having trouble starting the car at the minute. I can see air bubbles in the fuel line from the filter to injection pump. I was just curious whether or not my car has a lift pump as I can't hear it prime. I looked under the rear seat and there is what appears to be a pump with a float on it for the fuel gauge, but there is only one plug connector with a positive and negative wire on it, that appears to be for sending signal to the fuel gauge. Is this a lift pump?...i'm confused.

    Thanks

    Hi Bunty

    If you have a 1.9 TDi 90 or 110 no (under seat will have 2 wires)
    if you have a 1.9 TDi 100,115 or 130 yes (under seat will have 4 wires)

    Only the PD engined cars have a lift pump

    Regards
    Rick
