There are 190 DSG tow'ers about on the board. If they give you their figures a rule of thumb would be to multiply by 1.03 based on VW consumption figures of the Tiguan on the 150 manual, 190 DSG. The 150 manual will always give you better consumption mainly since it doesn't have the DSG although the 190 has more umf if you use it, but like for like consumption is the same with a DSG in the 150 / 190 guise based on VW brochure figures. I got this explained to me when I nearly bought a Tiguan. This is why 150 manual owners get better figures than us 190 owners. The penalty of the DSG not the engine, nice penalty thou.
