Hello i have a 2000 AUDI A-6 2.7T the engine light is on had it checked it is a p1411 code can I fix it myself

Secondary air pump valve implausible signal . Anything from a faulty connection or wiring issue to a bad air pump . I would disconnect and reconnect the plugs and check the wiring for bare spots first .

p1423 p1411
u either forgot to put the hoses at the air motor or air motor not working.the location is at the passenger side in front of engine behind bumper and right beside the a/c dryier.looks like a blower....
p1227 can not remember......
check light went on when the engine got warm?

p1423 look like a lot of works.remove upper engine cover and inspect for damage to vacuum lines. just go to yahoo and type vw p1423 code alldat

I just know the P1411, it means SAI System Incorrect Downstream Flow Detected.

P1411 = Secondary air injection system, bank 2 - insufficient flow detected.
Probable cause: Intake leak, hose(s) blocked / leaking, secondary air system valve / solenoid.

P1423 = Secondary air injection system, bank 1 - insufficient flow detected.
Probable cause: Intake leak, hose(s) blocked / leaking, secondary air system valve / solenoid.

check the air hose from the air pump might be leaking

P1411 - secondary air injection system flow too low Bank 2.
P1423 - secondary air injection system flow too low Bank 1.
Check vacuum hoses to combi valves ,
most common split air injection pump which is riveted with aluminum rivets,ck rivets if they coming out ,pump doesn't build enough pressure.
In this case take pump out and put bolts instead of rivets all around pump case.Repl. all rivets not only broken one.Bolts sold at HomeDepot , just find a needed size.

Are you sure that is the code?
Gm does not have a P1411 in the 2003 J body

for P1392 you have to change your Bank 2 CMP sensor
