Hello! I'm back again since my caddy insists on being bad. I've got some codes that popped up. one was teh EE E48 code which i understand is the EGR system(i know i need a new EGR valve). The other is an F32, F48, and F31 code. If anyone can help with identifying the F codes it would be fantastic. Unfortunately all the code sites i've found do not list F codes.
Any help would be appreciated.
