Hello, I have Audi A3 8V 2013 1.4 TFSI (122HP) for a year. When I bought it I done "small" service, oil change, all filters and service of air contidion. After 3 months / 3.000KM i got "Check oil level" warning message. I bought and put 1 liter of oil. 2 months after that i get that message on weekly / monthly basis. When I put oil, warning message dissapear, but even if I drive it a lot or just a few hundrets kilometers, the oil warning message appear again. This happens more often if I drive it in Dynamic mode. As first I checked under the car, but there is no oil leak. Next week i must go to service for oil and filter change (after 11.000 KM) and I will check with the service what will they say. Any suggestion or advice form forum experts?
