A6 Trouble
Hey Guys,
I"m a regular on the B5 A4 as that's what I drive.
Anyway, my Uncle has an A6 4.2 and it failed it's emission test.
Here are the codes:
P0441
EVAP Emission Contr.Sys.Incorrect Purge Flow
P1136
Long Term Fuel Trim Add.Fuel,Bank1 System too Lean
P1138
Long Term Fuel Trim Add.Fuel,Bank2 System too Lean
P1411
Sec.Air Inj.Sys.,Bank2 Flow too Flow
P1423
Sec.Air Inj.Sys.,Bank1 Flow too Low
Any ideas?
thanks,

Check all vacuum lines
I have 4.2L as well. I had the last two codes and fixed by finding a broken vacuum line. Happened to go from under brake fluid res. to front of engine in an underneath sort of fashion. Find the leak and more codes may go away.
