2015 X5 50i. 72k miles all stock. Got the malfunction from misfires on cold starts. Car was shaking on startup for a while even before the codes so I knew something was up.
Replaced plugs coils and cleaned injectors. Also unfortunately needed to do valve cover gasket on one side. Wow that's an expensive repair. BMW quotes 15 hours of labor. Thankfully my independent shop did me a solid on that.
