Can anyone shed any light on these codes ?
Didn't intend to make my first post with new ride a question about a problem but then thats how it often is i suppose !
Just purchased A D3 S8 which is (obviously )fantastic...except the dreaded EML light has come on twice within the first 6 days of ownership. Turned off light 1st time round in case it was somehow spurious but has come on again today so obviously an underlying problem. The codes are P1497 and P0491 both say "secondary air injection system insufficient air flow " on banks 1 and 2 respectively. Can anyone shed any light on these ? Is it likely to be the secondary air pump/ leaking pipe etc? Does it sound expensive !!! Any help be greatly apreciated |

Congrats on the car, pics are a must if you haven't already.
As to your problems, it could be a few things, and VCDS is a must to help you diagnose. If you don't have the manuals then get saving from here If you have VCDS do output tests to see if the secondary air pump is running. If it is then i'd start looking at the combi valves which are vacuum operated to allow the secondary flow into exhaust.

Manual 11 has most of the info on secondary air
Also if your using vcds you'll find the label files I made useful for the v10. See attached file here and unzip it into the user folder of vcds to have them available when you run vcds
