BMW 530i liquid leakage from exhaust pipe at ignition after sitting overnight on BMW 530i

Some BMW 530i owners report experiencing liquid leakage from the exhaust pipe during ignition after the vehicle has sat overnight, which is typically due to condensation in the exhaust system. This issue often presents as a trickle of water, particularly in colder weather when condensation is more likely to occur. The liquid is generally condensed steam that accumulates in the cold exhaust system, especially during startup when the engine and exhaust are cold. However, it is crucial for owners to differentiate this normal condensation-related leakage from other leaks that could indicate more serious problems with the exhaust system or engine components.
