Does a Water-Damaged Car's Computer Motherboard Need to Be Replaced?
2 Answers
Check whether the computer motherboard is damaged, and replace it if it is. Below is an introduction to water damage in vehicles: 1. Introduction: Refers to vehicles that have been submerged in water, typically involving the engine and transmission being soaked, with water levels exceeding the wheels and body seats, and prolonged contact between the vehicle's underbody components and water. Such vehicles pose significant risks, as the electrical circuits are prone to short circuits, fires, etc. 2. Repair: To a certain extent, they can be repaired, but even after repair, serious hidden dangers remain. The longer the soaking time, the higher the likelihood of malfunctions. This is similar to a watch falling into water—even if it is disassembled and dried, the watch may still malfunction and cannot be completely repaired. 3. Hazards: Since some sand and gravel cannot be completely removed and may remain in areas such as gears or belts, certain components are prone to damage, and there may be unusual noises initially. Generally, repairing a water-damaged vehicle involves first removing the seats, interior trim, and panels, draining the accumulated water, and cleaning the mud. The engine must also be dismantled to inspect electronic components, especially checking whether the computer motherboard is damaged.
When it comes to whether the car's computer motherboard needs to be replaced after being submerged in water, I've personally experienced this. After my car was flooded, the motherboard got wet but still worked at the time, so I didn't pay much attention. However, it didn't take long before problems arose—lights flickered randomly, and the engine even stalled. Later, when I took it in for repairs, the mechanic explained that water corrodes the internal circuits and connectors. Even if it seems fine initially, it will definitely fail over time, and repairs could be more expensive with potential recurring issues. My advice is don't hesitate—if your car has been submerged, take it to a professional repair shop immediately. In most cases, the motherboard should be replaced because safety comes first. Sudden malfunctions on the highway can be extremely dangerous. Additionally, it's best to have the entire electronic system of a water-damaged car inspected to prevent chain reactions. Saving money isn't worth sacrificing peace of mind.
