Error Code: 17831 - Secondary Air Injection System; Bank 1: Insufficient Flow

[Craig!]

Well some of you know I had my car on VAG-COM after my diagnostic light appeared and I got an error but I couldnt quite remember the exact wording. Well my own interface from Ross-Tech arrived today (took 48 hours from USA) got it all installed and plugged it into the computer and the full code is:

17831 - Secondary Air Injection System; Bank 1: Insufficient Flow

I presume as said before that this is just a problem on start up and warming of the CAT but I'd just like to confirm that. Also when doing an auto scan I get one other error that doesnt show up in the fault codes section, that error is:

00779 - Outside Air Temp Sensor (G17) 30-10 - Open or Short to Plus - Intermittent

Anyone know what's causing that one, is it the curse of the dreaded outside air temp sensor?

did you ever figure out what 00779 was? im getting the same error at the moment....

Im not 100% sure but the second fault code would make sense to be the outside temp sensor?

Yeah in the bottom of the n/s door mirror. Very common fault. The new sensor fits into the bottom of the mirror housing and the loom runs into the door.
