I've heard a lot of issues with injectors therefore I asked the dealer to look into that. They said the updated versions were put in around 20,000 miles... I find that a little hard to believe but I suppose I have to trust them?
I failed to mention I drove a 2015 550 at a different local dealer over the weekend and it didn't exhibit any of these issues.
