05 E60 P0491 Secondary Air Injection System Fault

Hey Guys,
I too have this issue for about 2 weeks. Reset the code twice using my new Android Torgue app (Droid Razr) in conjunction w/new Bluetooth OBDII (Excel) diagnostic plug device. Code came back after some research I have to dive in and do a complete systematic air flow check. This links may help:

I will check back in w/ my findings!

Thanks to everyone for the posts in this forum, I have learned a lot and saved thousands!
