Any ideas chaps, went to collect my A4 tonight, started it up OK, drove it 20yds, stopped it. When I went back to it, it started up fine but the throttle pedal did absolutely nothing at all, refused to rev up. Then the glow plug light started to flash.

Luckily, the guy I bought it off gave me my cash back.

Anyone have an idea what it could be? I am new to these vehicles.
