im the opposite of vw2011 , i have a 2012 tdi dsg passat and now that i did the tcs diasable i find myself driving with it off all the time . The tcs is way too intrusive on this car. I too have brand new studded snows 215 65 16 for some extra sidewall and ground clearance. A few weeks ago my steep driveway wasnt cleaned off yet as i just got home from work . i started going up and wasnt gonna make it , remembered the tcs off switch as i recently installed it and shut it off rpms and wheel speed came up and i made it .
Its so worth it , and it took about 2 hrs to do it .
