The (future) AGA secondary air port cleaning kit will only fix the "secondary air low flow" error message. The fault is generated due to carbon build-up in the heads that clog the port at the exhaust valve. The carbon build-up is due to the leaky valve stem seals. The AGA kit might allow sufficient cleaning of the ports to make head removal not necessary, but at $250 it is about the same cost as removing the heads DIY when you figure in head gasket and head bolt parts cost. Plus, pulling the heads ensure a better job of cleaning than using the AGA kit. IMHO.

I have 06 with 119k miles and I am having the same issues. BMW service wants 7900 to replace all the seals. 44 hours of labor is banana's.

When doing the value cover gaskets can you change out the valve stems at the same time?

Yes you can if your up for a big job. If you plan on doing valve seals then yes you will end up doing valve cover an upper timing cover. If you only plan on doing valve cover an upper timing cover its a lot more work involved to get to valve seals. Ultimately just do valve cover an timing cover until you are ready to tackle or have enough cash to do the valve seals.
