00 a6 2.7t with codes p1423,p1411,p0431,p0421
Ive got a 00 a6 quattro and its showing me these 4 cods p1423,p1411,p0431p0421. Im assuming the p1423 and p1411 are vaacum leaks and i should be able to find them. The other 2 codes Ive read are do to bad cats or some sort of a software issue about it being to sensitive. Im wondering if 1 of you audi geniuses can help me. I have already learned a great deal from a lot of you and appreciate this site a lot. Im wondering if these codes in this fashion point to a specific part and or fix or series of parts and fixes. And im really hoping I can avoid the dealerships insane rate on getting these p0431 and p0421 fixed. Is there another way to clear these software codes perminently without a $300 fix at Bergstrem. Thanks in advance

looks like an idea that would work but in the description of which cars it works for A6 was not in the list. Before I buy 2 (have dual exhaust and a v6) I wanna make sure some people have used them without any problems. I have a 2.7t and dont wanna do any harm (not that it seems like it could do any harm). Please if anyone has used it. Let me know. Thanks in advance
