BMW 550i GT fuel smell in cabin, oil leak, and check engine light issue on BMW 550i GT

Some BMW 550i GT owners report experiencing a fuel smell in the cabin, which may indicate a gasoline leak and poses a significant fire hazard. This issue could be linked to past recalls for fuel leaks and engine stalling due to faulty fuel pumps in certain models. Owners are advised against driving or parking the vehicle in enclosed spaces if a fuel leak is suspected. Additionally, some owners report an oil leak, often characterized by a burning oil smell, which may stem from leaking turbos or common areas like gaskets and seals in the engine. Diagnosing an oil leak involves checking for oil drips, traces under the vehicle, smoke from the engine bay, and burning smells from the exhaust. Furthermore, the check engine light may illuminate due to various factors, including oil leaks affecting engine performance or faulty components such as O2 sensors or catalytic converters. It is recommended that owners have a mechanic conduct a thorough inspection to identify the sources of these issues and address any potential fuel leaks promptly to ensure safety and prevent further damage.
