I was wondering if anyone else has had an oil hungry Euro?

Mine is brand new and between 1000 km and 8000 km it consumed almost exactly 2 litres of oil. Took it to the dealer to check it out and got the 6 month service at the same time (i.e. a $260 oil change), and no explanation, but it is now on "consumption watch", which means taking it back every 1000 km for 5000 km, so they can check the oil level. Somewhat inconvenient.

Has anyone else had to do this?
