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

Being as it's part of the warm up I would say it will be ok.

I'm in Warrington, well, will be early September. I have hooky VCDS, and will happily have a go, but my A8's engine module isn't accessible with my dodge lead, so couldn't guarantee it would access yours.
I would imagine Ray (tc4332) could help you out, he's in Wigan and is an awfully nice chap with legit VCDS. John.

Appreciate the thoughts John, its this sort of help that makes this forum one of the better ones out there. I have actually got the car booked in on Monday at an Audi garage (S & R Miller anyone ??) in Wigan,hopefully a reasonable fix
I will update the thread though for info purposes. Last edited by bigee; 10th August 2017 at 04:33 PM. Reason: info |

Sorry Guys.
I meant to stick my oar in on this and then forgot whilst nursing the new grandson. John is correct about being in Wigan but I doubt that I'm "an awfully nice chap". I do not have any personal knowledge on S & R Miller. I know that they are in Standish. I'd be happy to plug into your car if you want. We live in the Poolstock area.
