Have you tried starting it with the fuel filler cap open, could be an air lock, of blocked fuel filter.....

If you can, get a diagnostic computer plugged in and read what error codes there may be stored. It sounds like a crankshaft position sensor fault but the odometer display going off says to me there may be an immobiliser fault as it is integrated into the instrument panel. The only way to be sure is to get it checked by computer.

I would check the fuses and power supply circuits.sounds like one is missing and causing a problem with the immobiliser circuit.It is a separate control unit for this and not in the dash pod on these early a4 models.You are unlikely to get any accurate info from your obd scanner as cars of this age are not obd compliant.hth
