I ran my JB4 in my GLC63 for almost two years and never threw a single code. I had to remove it to get some recall work down at the dealer and just reinstalled it today. After install, I updated to the latest firmware. Everything looked good after initial startup, but once I get into the throttle, I am getting a CEL. Codes shown are P0300, P0600 and P42BB. I used to run all day long in Map 2 (93 octane) but I'm getting the CEL in Map 1.
I know I've been spoiled since I've never had an issue before, but I have no idea what could be going on. Hoping the attached logs may provide some insights to the experts. Any ideas?
