There's water in the air filter. Is there water in the engine?
If the air filter has been flooded, do not try to do a second start. Because the vehicle wading, the water will pass to the engine intake, the first into the air filter element, sometimes directly lead to engine stall. But most of the water has been through the air filter element, into the engine, start again will directly lead to engine damage, should be the first time to contact the maintenance organization for treatment.
If the engine stalls, continue to start the second time, water will be directly into the cylinder through the air inlet, gas can be compressed but water can not be compressed. So, when the crankshaft pushes the connecting rod to the direction of the piston compression, water can not be compressed, the large reaction force will lead to the bending of the connecting rod, the difference in the force of the connecting rod, some will intuitively see that it has become bent. Some models may have slight deformation, although after drainage, they can start smoothly and the engine runs normally. But after driving for a period of time, the deformation will increase. There is a serious bending of the connecting rod, resulting in the risk of breakdown of the cylinder block.
