P0411 - P1411 Fault codes Golf MK4 V6 4 Motion


Recommended Posts

Hi all,

 

I now own a Golf Mk4 V6 4motion 2003 year

 

Car drives nice and solid but every few hundred miles the engine MIL illuminates Vagcom pulls up P0411 and P1411

 

I understand these relate to the secondary air injection system (SAI)?

After a read round it seems to point to either the pump not working or hoses split??

Could someone help point me in the right direction please, where is the pump located? how to test it? Can it be removed? it is really required?

 

I know a few questions but trying to get a understanding of what may be my best route to take to stop the fault returning 

 

Thanks all
