What should I do if the BMW engine is flooded?

If the engine is only mixed with water vapor, the water from the air filter can be cleaned by simple treatment.

If the engine has a lot of water, but it does not affect the normal running, but the sound is relatively loud, it may be that there is a small amount of water in the engine oil and gasoline, so it is necessary to change the engine oil and clean the engine related accessories.

If there is a lot of water, it means that the engine has been flooded, not mixed with water, but the car has not started and the engine is not damaged. It is necessary to drain the water and clean it up, then reinstall it and change the oil with it, but the circuit system is unsafe.

Finally, there is too much water in the engine, and it can't run after starting. At this time, the cylinder, connecting rod and piston of the engine have been deformed, so it can be concluded that the engine has been scrapped, and only a new engine can be replaced, or the car can be scrapped directly.

Extended data

When the vehicle is wading, water enters the cylinder from the intake manifold. Because of the incompressibility of water, the piston motion stroke will be shortened, which will lead to the bending or fracture of the engine connecting rod. In extreme cases, the broken connecting rod will fly out and puncture the cylinder.

The reason why the automobile flameout in water is that the distributor loses its normal ignition function after the distributor cover is flooded, and the engine air filter element is flooded, which leads to the increase of intake resistance, the combustion chamber is flooded, and the spark plug cannot be ignited. If you restart the engine at this time, it is easy to explode.
