My check engine light is on and my scanner says the problem is: Secondary Air Injection Incorrect Flow.....does anyone know what this means....it has been on for about 3 months and nothing has gone wrong.

 

What was the DTC code? 16795? If so, it sounds like a bad secondary air valve, or smog pump. The smog pump is used to force air into the engine on startup. There is a little plastic tube that may be cracked or letting pressure out. Also, you may want to check your vacuum hoses. It may be a good idea to replace them anyways.

I think there was a recal from Audi concerning this problem. You may want to check it out, they will probably fix it for free.
