Code P0411 CEL came on couple days ago.
It was the first morning at 40 degree weather Thanksgiving and I'm driving and the CEL came on. Looked up the code and came up error code P0411 Air System, Incorrect Flow Detect. I've looked it up here at Audiworld and shows possible bad line to the secondary air pump.
Only thing is, I cleared the code today and has not come back on. Even in cold starts tonight it didn't come back on.
Should I even be worried about it? It should come back on if there is a real problem, correct?

There's a vac line that runs from under the intake mani
around the back of the engine to the Combi valve (secondary air injection) - it's a round, chrome topped valve on the back left (passenger side)of the engine - you can't miss it. Check this hose. I'd be willing to bet it's got a leak. Replace it and you should be good to go.
Let us know - this is the most common cause for this code.
