The EPC light is intermittently coming on in my 2013 Audi TTRS. The fault codes are only present when the EPC light is on. If I turn off and turn on the car quickly the EPC light goes out and no fault codes. The full VCDS scan with the EPC light on is below. Any advice on what to do next is appreciated.

There are several items to check: vacuum leaks, vacuum canister/actuator, carbon build up inside the Intake manifold itself, broken plastic rod or flap.

I would start with trying to diagnose the problem with some quick checks like vacuum, or linkage, and then disconnect the actuator and see if you can manually open and close the flaps ; it should feel free without binding or rubbing. If there is any interference or jamming, you will have to remove the intake for a better look. Or, invest in a bore scope for a in situ look.
