Hi All... Got an A6Q with 3 codes 17819, 17831,& 17862. Two are for low air flow in the secondary air injection system and the third is for a short to
ground in the #1 oxy sensor. Anybody know anything about where to start
repairing this system. Didn't get a chance to look at the sensor yet. The two other codes are for secondary air flow that is too low. I am going to look at the air filter,the fuse and relay for the air injection system,the air injection pump, the solenoid,and the check valve, in that order. Any help or information would be much appreciated as I really want to avoid the dealer.... Cbob
