I have a 2021 X3 DS Turbo R 172 hp. What could be some signs/risks of improper break-in? I babied it the first 10 miles. Then for the next 20 miles varied the speeds on some long distance runs with a couple hard pulls here and there but not quite full throttle. Everything seems to be running running fine but when I checked the oil it seems thin/runny and has a rich smell to it? Is that. It that normal for a brand new machine? Also engine seems to sound very noisy imo?
