Audi A5 high oil usage
 

I bought a used 2010 A5, with 100,000 Kms. I have put on 16,000 in the last 4 years since. It uses inordinate amounts of oil; ie. 4 liters to go from Calgary to Vancouver and back. It is the only car in my life where I don't carry a 1 litre spare oil jug, but a 4 litre jug. I park underground, on a clean painted floor. No leaks. No blue smoke or smoking indications. I remember hearing of a recall on the motors from 2010 to 2102 (I believe). How may I find out more? I go in for 115,000 km service next week. I had mentioned it to Audi dealer last month, when I had battery replaced. They didn't seem to want to confirm it, or seem interested in having it resolved. I appreciate any help! Thanks
