Can Two Ignitions After Wading Be Detected?
2 Answers
Two ignitions after a car wading can be detected. Here is the introduction to the inspection of vehicle wading: 1. Second ignition: After the car wades, the starter motor will only be activated again if the engine stalls. At this time, the starter motor does not respond, which is considered a second ignition. Second ignition refers to the situation where the car stalls underwater and then the key is turned to ignite again underwater. If you have purchased wading insurance, whether you ignite or not corresponds to whether you can claim or not. 2. Damage situation: Normally, if the vehicle stalls in water, there is a 50% chance that the engine will be damaged. However, if the engine is started again after stalling, the engine will definitely be 'scrapped'. Therefore, whether driving or parked in a community, underground garage, or street, the car must not be started again after stalling in water. 3. Insurance exemption: Some insurance companies will treat the second ignition after stalling in water as an exemption clause for wading insurance. That is to say, if the car is submerged in water and the owner attempts a second ignition, the resulting engine damage will not be compensated even if wading insurance is purchased.
Starting the engine twice after wading through water can definitely be detected. I often encounter this issue when repairing cars. For example, a car was stalled in water, and the owner hastily tried to start it, resulting in water entering the engine. A second attempt could allow water to enter the cylinders, causing hydraulic lock, bending connecting rods, or damaging pistons. During repairs, we use diagnostic tools to scan the ECU for error codes indicating failed ignition attempts, combined with compression tests to check cylinder pressure. If the pressure is low or there's abnormal knocking, we remove the engine cover to inspect for bent connecting rods. These signs are very obvious and not as easily concealed as minor issues. So, never force-start the engine in deep water; it's safer to call for a tow if the engine stalls. Develop good habits: after wading through water, always check if the air filter is wet before starting the engine.
