Hi guys. Just wondering, is driving in manual mode more fuel efficient than drive mode? I started driving in manual mode 90% of the time since i like to switch gears myself (around 3000 for the first 3 gears) and heard that it's better for the life of the DSG transmission. When I come to a stop at a light etc I switch it from manual to drive to reduce my rpm at idle then switch back when I take off again. Does this constant change damage the engine as well? Cheers for your thoughts.

I have a 2011 Polo GTI 7 speed DSG, and yes with the engine oil problem... :/
