Why is the Skoda Fabia temperature gauge flashing?

[SanAutumn]

Skoda Fabia temperature gauge flashing indicates a coolant temperature warning light malfunction or high coolant temperature. The specific reasons are as follows: Low coolant level: This is the primary check you can perform yourself. If you're on a highway or in a remote area without coolant, you can temporarily use water as a substitute. Important: Do not immediately open the radiator cap or reservoir cap after stopping the engine, as the high internal pressure may cause sudden ejection. Wait until the temperature cools slightly before slowly opening the reservoir cap. Dirty radiator: The radiator has numerous cooling fins with small gaps that can accumulate debris, fluff, or sludge, reducing airflow and cooling efficiency. In winter, reduced cooling efficiency isn't critical due to low ambient temperatures. However, in summer when ambient temperatures are already high, a clogged radiator with poor cooling can easily cause overheating. This issue can be resolved by simply cleaning the radiator.
