Crankshaft and piston are irretrievably damaged. the problem is so great that the entire engine needs to be replaced. I have always serviced the scooter only at a BMW warranty service. Just a year ago I heard strange noises, like metal hitting metal. I told the repair shop (BMW), but they didn't...
I have same sounds on my c400x sport (2021) at 13 000 km...after 3000 кm more, the engine died....and now I'm waiting for a new engine from Germany. I was lucky I still had 24 days left on the warranty.
