Hello all, I noticed my fuel mpg's had gone down recently between fill ups.
I hooked up my Vag-com and noticed in "measuring blocks group 000, box 10" the value for Air Mass was 133. The info box that popped up said it's suppose to be between 69-111.
Group 003, EGR System test at idle, air mass value was 195 with EGR on and 445 with EGR off. Suppose to be between 230-370.
So what's wrong here? Is my MAF on the fritz or my EGR?
Would these value readings throw off my MPG's? (got 36 mpg's on last tank and I drove it normal this time )
Is there anything else I should do in VCDS or change in adaptations?
I would like to be at the 40-45 mpg's range again.
Thanks for any replies that may help me.
