Does anybody know waht these codes mean off of vag-com. 1. catylsyst effiency below freshold. 2. 2nd air valve incorrect flow. And sorry for being a pain does anybody know if the lambda should be at the front or the back of the cat. cheers!
i havnt tgot the number for the code i will have to get it off my mate again doh! it has meant to have a re-,map so that would make sense if the second lambda has been mapped out, but it is only running 6-7 psi . i just think the cat might have been put back on the wrong way round.
oh sorry it has got a standard cat on but looks like it has been put back in before selling the car as there is a little section of stainless straight after it, looks like a bit of bodge, would the best idea to de-cat it.
were these codes on when you bought the code. the reason i say this is because if he had a decat on and then that would of brought the codes on, he has prob put the standard cat on to sell but not cleared the codes
He defo wont be able to put the cat on thee wrong way. If you are running 6-7psi then its not remapped because thats standard boost pressure.

The cat has clearly been welded back on as the 2 types either side of it are stainless and you can see where they have been welded onto the 3 bolt flanges.
The postcat lambda is at the front of the cat quite close to the pre cat lambda which was mentioned might not be correct.
