hello
I,m sorry but I'm away from the shop for next 4 days, so I can't check these faults for you. A6- what year?????
P1423, EGR it is for exhaust gas , 2 valve engine had a lot of problems with intake manifold cloging up with carbon where EGR valve is, and this may set this fault.
P1411 seem like bad CAT but I'm not sure till I go back to shop, same with P1122 and P1140.
P0160 is for O2 sensor on left side after CAT. (bank 1 is R/ side, bank 2 is L/ side.
Good luck pltech
AnswerOK
So, you have 00 A6 with V6 motor
from the top of my head P1423 and P1411 is for secondary air system. There was a lot of problems with vacuum hoses going to combi valves on the back of both heads. Most like it is the hose on the right side , right by the valve. But check your all vacuum hoses. I will do this first, if you find any broken hose, replace it and reset all faults. Vacuum leaks may cause many problems.
good luck pltech
