Hi
I'm new to this forum, I see there are alot of smart people here. My qyestion is that I have a 2001 VW Jetta VR6 The check engine light has come on had It scanned and the code was PO411 (Secondary Air Injection System Incorrect Flow) on the DTC Pending (Codes)said ( No Faults Detected) the problem is when I clear it ,it goes for a week or so and comes back on.. In my State New hampshire if you have a Check Engine Light on during Inspection they fail you if I erase code error before I go in will they detect anything through there Equipment I would really like to
fix the propblem if any
Thanks for any Help
Steve

if you clear the code and you have it inspected before the light comes back on then they won't be able to detect it.

not sure what it is, MAF sensor, possible vacuum hose leak, not sure

probably a vacume line off of the deverter valve
and it will not pass a test if you clear it before you take it in
it needs to go through a drive cycle before it gets ready status
thats why it takes a few days to retriger the light
