H-CAN driver error C63 2013

Hello guys, I just bought a new to me C63 coupe 2013 yesterday with 37.5k miles. It was running great but feels a little rough at idle now and I can feel the rough running especially through the break pedal when at idle. I managed to find out how to check the error history codes and at literally 37k miles it was throwing up an H-CAN driver error but after googling I can’t find anywhere what that means. Does anyone here know? Just want to know if there is something wrong with the car and they tried to hide it by wiping the error. Thanks
