Hey guys,

I had this code come on, had it cleared and was off for a few weeks then all when i was driving and went to shift with my hands full --- ooops bad girlfriend haha I accidentally revved it in neutral going into 4th and the code came back on!

same thing again - secondary air injection failure - from a buddies' VAG. From my research on here you guys are saying could be DV well i have the 007 in as of a few months so i want to single that out but heres what tickles my brain:

I didn't just poke holes in my airbox mod - i chopped it right open and put mesh over. Is it possibly getting toooo much air??? After i did the airbox mod my coilpacks & maf went so im thinking i should plug the airbox mod right up...

'01 a4 1.8T S/P 5 speed

Thanks Guys!

-Travis

 

Secondary air injection is used during warm up, to give the CAT
enough O2 while running rich.
