My car started to sound exactly like this. Something with damaged valves. Full engine was replaced, including both turbos. New engine, new turbos straight from Germany. Took almost 4 weeks, but everything was covered under warranty. 52k kilometers old engine... the bill for BMW was insane, ~23k USD / ~20k EUR
Now I’m just affraid this will happen again, but car won’t be under warranty anymore... damn
