Hi, I read a couple of your posts related to M278 cylinder scoring, and appreciate what you shared. Poking around at the data, there seems to be enough people affected with it that it warrants consideration of negligence on MB. I have a 2015 and just got the scoring diagnosis at 77k miles. Any guess how long I can keep it running? Are you experiencing the problem? Trying to think through what to do next. Appreciate any insights you might have. Wished I dig deeper into this pre-purchase! Cheers!
