audi/vw folks... q7 burning oil?

so, wifey's '13 q7 is eating oil. 2-3 quarts between oil changes. the check oil warning comes on about 3-4000 miles after a change. 79k on the clock. it is supercharged. no smoke coming from exhaust. no stains on the driveway. i have not yet checked the spark plugs but it's on the list for this week. what else should i look for?

it is due for service and i have an audi guy down the street that i like. just want to have a little knowledge in my pocket before i take it in.

 

PCV is the most likely culprit especially if it’s an early 2013
