Code P0492 - Secondary Injection System?
My check engine light was on and I've cleared it but it came back just today. What would I need to replace? I've looked online and it seems ppl are replacing the air pump? The SAV drvies fine and it doesnt seem like its affecting anything... I still would like to fix this issue. Anyone else experience this problem? Any input is appreciated, thanks!

Start with the vacuum hoses. I was able to get away with a $7 hose repair to solve the problem. BMW vacuum hose seems programmed to die within a few years of fitting.

It might be the Secondary Air Injection got clogged. You can follow the process of the guy on YouTube to unclog it.
