    So I just bought a 1996 Passat TDI sedan. There are spotty maintenance records and the gentleman who owned it has passed away. His kids do not know anymore than I do on the history. I'm working through the car to see what needs attention and to generally be aware of what I have. That brings up the ECU.

    This car has a silver case ecu #028 906 021 GQ. Has this car had the smoke update? Is it safe to say the 5th injector is effectively disabled from this car? I popped open the ecu and it appears the two chips are stock. Bosch hhh683 chips.

    Also, what nozzles should the car have?

    Thanks,
    Andy

    GQ is the smoke recalled one, esp since not in plastic case.

    Nozzles are probably stock, check out the mk3 new buying guide for common problems, maintenance!
