Why do the temperature gauge on your mk4 astra read 50c?

If the temperature gauge on your MK4 Astra reads 50°C, it could indicate that the engine is not reaching its normal operating temperature, which is typically around 90-95°C. This could be due to a faulty thermostat that is stuck open, allowing coolant to flow continuously and preventing the engine from warming up. Additionally, a malfunctioning temperature sensor or wiring issues could also cause inaccurate readings. It's important to diagnose the issue to avoid potential engine problems.
