Is there a quick fix for Mercedes misfire code P0410? secondary air inj valve? on 2001 Mercedes-Benz E320

I've read it could be the check valve. I'd love to do it myself instead of paying, I'm not great with cars, however i have friends that are pretty good at them. I had autozone clear the code and the light came on after about 15 miles or so. I've read the check valve requires a special tool. Please help!
