BMW 528i xDrive burning smell and smoke from brakes and engine due to possible valve gasket and booster issues on BMW 528i xDrive

Some BMW 528i xDrive owners report experiencing burning smells and smoke from the brakes and engine, which may be linked to issues such as oil leaks from the valve cover gasket or booster problems. These burning odors can occur when oil leaks onto hot engine components, particularly the exhaust system, leading to vaporization and an unpleasant smell. Additionally, oil dripping onto exhaust parts or the engine block can exacerbate the situation, especially when the vehicle is stationary after driving. Some owners have noted that smoke becomes more noticeable under these conditions. To accurately diagnose the source of the leak, a smoke test conducted by a professional is recommended. It is important for owners to seek a thorough inspection by a qualified mechanic to address these potentially serious issues.
