BMW 528i xDrive burning oil smell and smoke from driver side front wheel well on BMW 528i xDrive

Some BMW 528i xDrive owners report experiencing a burning oil smell and smoke coming from the driver side front wheel well, which may indicate several potential issues. These problems can stem from oil leaking from the valve cover or rocker cover gasket, leading to oil dripping onto hot engine components, such as the exhaust manifold. Additionally, the presence of white smoke during cold starts could suggest an oil leak affecting the cabin. If the thermostat is at midpoint while idling and accompanied by a smell and white smoke, it may point to a malfunctioning thermostat or a coolant leak. Furthermore, some owners have found that a disconnected breather hose under the intake can mix exhaust fumes with oil, causing similar symptoms. It is crucial for owners to address these issues promptly to avoid further damage and ensure safety, and consulting a mechanic or BMW specialist is recommended for proper diagnosis.
