Octavia's water temperature gauge illuminates because: The engine's water temperature is too high and requires stopping for adjustment. The water temperature gauge displays the coolant temperature, helping the owner understand the vehicle's condition. When the car's water temperature is too high, the owner should stop and wait for the temperature to drop to normal levels before continuing to drive. Below are reasons why the water temperature gauge may not move: 1. The water temperature gauge's power line is broken, or the gauge's heating coil is burnt out; 2. The water temperature sensor's heating coil is burnt out or the contacts are poorly connected; 3. The water temperature sensor's wiring is poorly connected or broken; 4. The voltage regulator supplying stable power to the water temperature gauge circuit is damaged.

How to Deal with Water in Audi Headlights?

For relatively minor cases of water ingress inside the headlight, the fog will dissipate through the vent tube as the heat builds up after the headlights have been on for a while. Disassemble and open the headlight cover, then air-dry it and inspect the surface of the headlight for any damage. If no damage is found, proceed with reassembly. If necessary, remove the headlight cover to check for any damage on the surface. If any abnormalities are detected, it is recommended to replace the headlight rear cover seal and vent tube.
