Re: probably need to rebuild the secondary air pump

Thanks, should this cause any problems if not fixed immediatly, or will it go away when it warms up and the seal expands?

I'm dealing with the same thing right now...

I already rebuilt my pump but the code keeps coming back, going to try a new solinoid and kombi next.

wont cause problems...

the pump turns off about 2 minutes after you start the car you can hear it, you just have to live with the cel on if you ignore it.

Might want to make sure your hose it not broke. Any leaks could give

you a cell also. And that flex hose can become pretty brittle.
