P0491, P0492 2ndary vacuum bank 1 and bank 2
Check engine light went off. I plugged in a friends OBD2 computer at work and it threw these two codes. Anyone have any experience.

Re: secondary air pump is either going bad or not working
Any idea as to the typical cost to replace the secondary air pump? Audi dealer is $1000 and wanted to see if this is a typical price.
My car has 100k miles... is this a typical failure at this mileage?
Thanks in advance.
