After upgrading VGSG module got Christmas tree of error lights and RWD. Car seemed to shift and pulling up rpms muuuch smoother.
But of course ABS/DSC went down and it's quite unsafe on snowy roads, so I coded VGSG and everything seems fine. But AWD again.
I have a suspicion that AWD eats tons of gas. On the short commutes, my car runs only 200 miles/tank. But on the highway it's up to 400. Could you guys post your mpg just for the reference?
