p1411 and p1411 need som advice
got 2000 a6 2.7 with p1411 and p1423 codes on it, scanned it and looks like its a evap system thing, dealer replaced the air pump codes keep comming back, wondering if i can fix it alone?

P1411 and p1423 are secondary air injection codes... If the air pump has been repalced it is either a vacuum line, a valve, or a plugged air line to the manufold. Since both sides are showing codes it probably not one of the valves.
I would guess that 75% of the problems with Sec Inj codes are vacuum lines

The pump is low on the left front of the vehicle with a large (1" os so) plastic feed line going to the front upper center of the motor. It feeds two black valves. connected to the valves are small vacuum lines.
