Thanks for the input. I have brand need MAFs so I hope one is not bad. I used my Torque generic scanner and both MAFs seemed to dead normal. At cruise they were jumping around. Brakes were out as I limped it home most of the way. It seemed to come back after a period of decelerstion, maybe built you vacuum. I searched all last night for a vac diagram. Only found SAI and pcv routes. Anyone got a full diagram?

Another note - whike looking around under the good with engine running, I could hear a very loud hollow sucking sound. Today I will pull the airbox and have a look and VAG it.
