16795 - Secondary Air Injection System ? from decat

[insanekiwi]

I noticed on regular VAGCOM scan that after de-cat I got this fault on engine.
I am guessing this is from decat, as it can't function properly to warm it up quickly. Never had this fault prior to decat.

I get no CEL lights - as I have REVO Stage 2 which removes warning. No engine or exhaust warning lights.

The car sounds and drives normally.

? from decat, I am assuming? It has straight through pipe with resonator. Has sensor plugged back into the pipe.

I've got some issues relating to this as well with my car, although it's stock. I believe the air pump pumps air straight into the airbox. The air-pump my have failed due to condensation building up and shorting it out. This is what happened with mine (over 5 years). I had it replaced last year around December but have since had further faults. The other faults relate to other components in the system overall. There is another valve and solenoid in the system which determine how much air is pumped and when etc. I'd get this system checked by your mechanic first.

I could be wrong, but i thought the aux. air pump had nothing to do with the cat, merely just pumped air into the air-box so the car doesn't run rich when it's cold?
