    Hi
    I am new to this, so please excuse any errors.
    I have a Passat 1.9tdi 1994 z1 engine. The problem the engine on tick over is rev rev rev hunting slight throttle and it stops.
    Can anybody assist, also can anybody suggest a plug in reader for this age of car, I have tried a modern one which will not read.

    OBD 1 reader ?

    Modern ones are OBD 2

    However it could be that you need a VW computer its that old ie pre OBD 1

    The 1Z (not Z1) engine is not OBDII compliant so you need a proper diagnostic system such as VCDS.
