Coolant expansion tank is leaking on fuel injectors, coils and plugs on engine below causing ‘drivetrain malfunction’ which puts vehicle into Limp Mode. Car can begin to shudder, misfire and stall. BMW has an SIB on the expansion tank, but has done nothing to address the components underneath that get damaged. Feel free to Google BMW M5 coolant expansion tank issues.
