Hi Guys,
Just bought an 04 berlina. As part of the sale, the Comptech Supercharger was uninstalled.
Ever since I have had a P0411 error. I know it is for the secondary air system. I had it back to the hack that unistalled the super charger and in 4 hours he was unable to fix it.

So I took it to the dealer, and they think the air pump needs to be replaced. $800 buck and somehow I don't think it is the problem.

Has anyone run in to this before?
Does anyone that has experience with the super charger, have any ideas what to do next?

Could this have to do with the ECU flash?

Help.
