Secondary Air Pump system will not complete drive cycle

There is a reason those pumps are so pricy. They have to generate enough volume and pressure to overcome the exhaust pressure and then some.

I still think OEM is stupid expensive. I would probably get a used one vs. buy OEM. (especially knowing how to use a 5 series or 7 series model on the e53) (more source material)
