They both have the same piston rings!If you have the 150bhp version they dont burn oil.
The 184 cuna engine will at some point start burning oil and at low mileage, 50000 onwards.
The oil control rings are responsible for this. They are specced to be on the loose side and they don't seal as older engines from the VW range do. Its said to be a emission control thing.
VW state its normal to burn up to 1000ml per 1000 miles.
Common complaint and well documented on the forum.
