Audi A6 EPC light and intermittent throttle Sign In

Car is an Audi A6 C5, 99, 1.8T.

Hello to all.

Dropped the Mrs off at the train station, driving back and my EPC light came on. Drove about 300ft more, throttle stopped working. Was on a hill round the corner from mine so I rolled home. Left it for 20 mins, had a Google, started it back up and got into 3rd gear - throttle stopped (EPC light was still on). I can go out now, start it, EPC will be on and the throttle is fine but I can't go far at all as the throttle just switches off it seems.

Had a look around online through forums etc, a lot of folks are saying its the throttle position sensor, its dead and needs replacing. What else could it be?

My diagnostic port isn't visible, maybe pushed up under the dash, may have been removed but I can't use the reader. Gonna ring Audi tomorrow, get an idea of what I can do regards the port and the issue with the throttle.

Any help/guidance is massively appreciated, cheers.

You can't simply guess. You need to read the codes and diagnose it properly. The TPS isn't serviced separately.. It is integrated into the electronic throttle body and you don't want to know what that costs
