Ive been told a may have a faulty MAF ,although i have power,i dont have economy.
A4 tid 130 (awx engine) only does 24.6 m.p.g !!!! ive replaced temp sensor,ive heard a fault maf will give wrong readings (although will still work)

How can i check the readings via vag-com?
and what are good readings and what are bad?

Unless theres another reason its heavy on diesel!

16.00 pounds it used,it did 94.6 miles town driving @ 91.9 pence per litre.
