    Hi
    My 99 a6 2.5 tdi cut out yesterday. managed to get it towed home ok.Called a mobile diagnostic mechanic out and it said the control module for injection pump has packed up.

    Audi says you have to buy an exchange injection pump+ control unit for 1500 +vat
    Found complete pump and unit in the brakers for 400 +vat

    What I need to know is can I just replace the contol module which is bolted on top of the injection pump which is a 5 min job or will I have to replace the whole pump unit ?

    Got this from elsawin
    For security reasons, in all vehicles as from the 2002 model year the injection pump is integrated in the immobiliser system.
    t When an injection pump has been renewed, it must be re-adapted to the immobiliser (same adaption as when replacing the engine control unit), otherwise the engine will not start.
    In theory a second hand pump should work but the pump has to be timed to the engine. If you pm me with an email i can send you the procedure, but it looks like a replacment pump comes preadjusted to match the timing setting on the engine. Anyway I'll send to you and you can see what you think
