Check Engine Light - Secondary Air Pump

[flyride]

Thanks, I swapped it out, still have the problem.

Check engine light came back on after 70 km's with same error about Secondary Air Pump. Pump runs a lot of the time, sometimes it doesn't. This Porsche shop I took it too thinks it may be a valve? They say the heat from the engine can cause it to screw up. Any idea what valve it would be? Or a p/n or something so I could try and source a used one? They said it would be 4 hours to take off the intake to get to it, plus $400 for the valve, plus the time to put it back together, and no guarantee's that would fix it. So I decided before I drop a grand on it, I'm going to research it a little more and try and do it myself.

Any info/advice would be great!
