just came in 2000 audi a6 2.7 automatic, purchased it at auction yesterday with check engine light. the car has around 82k, bought it with the CEL light on, today hooked it up to my vag scanner i got 2 codes p1411 and p1423. I think its something to do with vaccum lines, but which once are the vaccum lines? 2.7 is totally different than the 4.2 or 2.8. Did anybody have the same problem? please help, before i bring to my buddy jakes automotive and he charges me couple bux to get this thing fixed, by the way when its fixed its going for sale, maybe will be interested

 

secondary air injection... check van line to the pump

not sure where it is on the 2.7t but on the 2.8 it is under the intake box

i was also getting similar codes when my crank case breather cracked by the throttle body, again in a 2.8 though
