Hello after a minor crush with my car the coolant light went on. When i have the radiator checked at the service, there is no problem and antifreeze and water full. The service tried to turn the light off but they could not. They checked the cables and the sensor but said there was no fault. They said that under the water tank, the glass water and coolant sensors were working parallel to each other. (After the accident, the water glass warning was not lit.) When the sensors are removed, the glass water light on along with the coolant light. But even though the glass water goes out when they replace the sensor, the coolant never goes out. There is no leakage or water reduction in the water tank. But they still said that the water tank should be dismantled and looked inside. (for sensors i dont know) Has anyone experienced this problem before? I thought the sensors were dislodged because it burned out after the accident but i think i was wrong. Thanks for helps.
