My Ride: 2005 530i
p0411 Secondy Air -- valve or MAF
Hi,
2005 530i I get this code periodically. The secondary air pump definitely works. I removed the check valve and tried to clean it with carb cleaner, however the angle of the passages made it difficult.
I don't want to replace both the check valve and the MAF if I can avoid it. Which more commonly fails? Any experience with this?
thx
