If it starts up without any problems, it sounds like the immobiliser isn't disengaging. Make sure all your door/boot/bonnet are firmly shut then lock and unlock the car. When you lock the car you should hear a horn beep once.

Hopefully that might work but if it doesn't, there must be someone on here with plenty more experience and knowledge about these than me.

Most likely the ignition barrel 'reader coil'.

thanks all, but i think i put this in the wrong section, it's an A4 i've got not an 80 (twerp!!!).

have you found out what the problem is, and more importantly have you found a cure. i'm having similar problems.

thanks rob

Does the immobiliser light go out?
