My oil consumption has gone through the roof over the past 6 months, using 1ltr every 600 to 800 miles. Car is a 2.0 TFSI SE SLine Q, 2007. Do 50% M-Way 50% A and B roads. I do boot it now and again but mostly stick to med revs. Car runs like a dream, no loss of power, sounds as good as it always has. Done 72K and i've owned it from new. Petrol consumption is about 31mpg. I've read lots of posts about piston ring issues, crankcase pressure valves and software updates - is there a defo answer to this?
