Hey guys. I am new to Audi and I am having a problem. I have a 2003 A8L with 60,000 miles and the check engine light came on this afternoon, however, the car is running fine and has no noticeable problem as far as performance is concerned. Any help would be much appreciated.

 

uhm take it to autozone and have them run a diagnostic on it they will tell you whats throwing the code with out that i dont think anyone can help you

 

If I can't take mine to Autozone is there any other way of getting the codes?

 

Buy a code reader.

I think advance autoparts does it too but if you cant get to them either then yeah your gonna have to buy a code reader

 

tighten your gas cap

 

The code that came up is P0491 - Secondary Air Injection System Insufficient Flow (Bank 1). Anybody have any clue on how to repair this? Thanks.

Thanks. I took off the cover and sure enough, on the top right the hose was disconnected.

 

I had this same code pop up. Can someone tell me or provide a picture of what and where this air pump is at so that I can see if I have a loose hose?
Thanks
