I replaced my air filter this weekend with a standard Porsche air filter from the dealership. Brought it home, put it in, start it up...CEL lights up right away.

I disconnected the battery terminal to clear codes and 40 miles later I have the CEL back.

Yes, I reconnected everything properly and have double checked my work.

Anyone have an idea on this one?

 

What are the codes?

 

pull the code and post back.

 

Codes:
P0410 torque converter solenoid sounds like it is stuck OPEN. Any advice on this guy?
P1411 secondary air injection system. I've had hoses replaced and the pump itself. Any thoughts?

Other than the above two codes, I believe this CEL to be related to my need to replace all 4 O2 sensors. Since I wrote the original Post, the light has disappeared, which as been the case with my O2 sensors (officially diagnosed by Porsche mech).
