EPC light just come on

Folks
3rd service due in 100 miles (booking into Audi main dealer next week), just this morning low oil light came on (never had a problem with oil before today, in 46K miles) and then about 5 mins after, EPC light came on. Engine feels responsive and no detectable issues - kept speed to 40 on way home just in case. Handbook suggests big problems and get it sorted straightaway
AUDI dealership now closed until Monday - anyone any ideas? all be solved at service or do I prepare for something worse?

Hmmm not sure but does the tfsi have variable valve timing? My 3lt V6 put up the low pressure light while I was on a track day (the v6 suffer from oil surge in fast corners so make crap track cars) it caused a ecu fault and I needed to reset the the cam solanoids via vagcom (output test) to clear the fault codes
