My Ride: 2003 330xi
Secondary Air Pump & Valve

Over the past year+ my 2003 330xi has given the "secondary air flow too low" code 3 times. No associated symptoms. So, hardly a pressing issue. The dealer says I need a new secondary air pump and valve and the service will cost over 700 bucks. From what I have read on this forum, the valve typically goes bad first and ultimately causes the demise of the air pump. I am thinking since the error code pops up so rarely, perhaps the air pump hasn't gone bad yet and I can get away with just replacing the (much cheaper) valve.

Is this wishful thinking or am I on to something?

Can anyone point me to a DIY on this?
