I know this is not the forum for this but I would just like some help... I just tested my cousins 2000 golf gti 1.8t and here are some error codes it came up with... (Her CEL is not on, but I would still like to know what some of these mean?) Help is appreciated:

(do this in 2nd gear on freeway). The mass flowrate should be 80% of your engine HP, e.g. 150 HP = 0.8(150) = 120 g/sec. The coolant sensor G2 is also probably bad. I had the exact same problems on my wife's VW Passay w/ the 1.8L engine. New MAF (replaced under warranty) and a new coolant sensor fixed the problems.
