I'm going to guess a MAF out of spec. Order a new for $50 or less.

MAF - is this number of VAG "06a 906 461 a" (air volume meter)
and of what is the difference between "06a 906 461 a" and "06a 906 461 ax"

My Engine is AEG 2.0

Hrm.. no idea. But I also have an AEG 2.0 and about a year ago went to www.1stvwparts.com and ordered the one for my year model for $39 and it solved my problem.

Mass Air Flow sensor, it's located on the top portion of the air filter element box (has the wire bundle plugged into it).

1. VCC is Battery + and gnd is ground -
2. Don't know
3. XP2 and 3 - notice the black bar on the top posts? That's where to jumper.
