    Wifes 1.9tdi ASV , was reporting fuel temp sensor out in fuel pump. So had this replaced by a diesel place. Now still no power and smokes loads.
    There is air in fuel line so replacing that.
    No codes reporting . dont think turbo is kicking in.( was replaced just over a year ago)
    I did play my my mates vcds and try block 11 to get the N75 to cycle but not sure what i should be looking at i had presumed when it clicks in to on the engine tone should change. but nothing readings all stay the same.
    Should i try replace the N75
    Oh we have been running on bio for a bit prior
    thanks.

    Just called Audi for price on the fuel pipe. :scared2: £86.15 WTF its 2 bits of plastic and rubber hose!!!!!

    Had a quick look but have no tester to test properly and couldn't see anything . Its much worse since drive back from garage.. very smoky. its whiteish and smells of fuel. Could the air bubble be a sign of pump timing. it was running fine up until a about a month ago.

    if it was boost leaks youd have black smoke, white smoke is water being consumed
