Just got a notice from Dodge that they are recalling my 2010 HD 2500 because it might a a software error that prevents the EGR cooler bypass valve diagnostics from running after detecting a pending fault, disabling the deNOx without illuminating the MIL. Short story, the EGR might not be working and the lights ain't coming on to let you know. Sure hope this hasn't damaged anything in the elaborate carbon burning equipment. Film at eleven.
