2004 A6 Quattro error codes P0491 & P0492
I have a 2004 Audi A6 Quattro with 76K miles. last night driving in cold weather on a highway I received a check engine light. the error codes that I had pulled today were PO491 & PO492. Secondary air injection system insufficient flow bank 1 & 2. The car seems to be driving fine with no decrease in power, acceleration etc. Can I drive this vehicle for a couple days until I can have a mechanic look at it? what could be the potential problems? thank you so much for your help

The air injection system if for emissions purposes , it will not effect the way the car runs. If both codes appeared at the same time you might have a bad vacuum hose , pressure hose or a bad air injection pump.
