The engine coolant temperature warning light is located on the fuel gauge in the instrument cluster, Instrument overview
The following table explains what to do if the engine coolant temperature warning light ¿ does not go out a few seconds after the engine is started or starts flashing while driving.
Flashes Possible cause Proper response
~
Engine coolant temperature too high.
² Stop! Pull off the road and stop as soon as you can do so safely. Stop the engine and let it cool down until the temperature is in the normal range again. Check the engine coolant level and add engine coolant if needed. If the engine coolant level is correct or the problem continues after adding coolant and driving a short distance, do not drive any farther. Contact the nearest authorized Volkswagen dealer or authorized Volkswagen Service Facility. If the coolant level is correct, the overheating may be caused by a radiator fan fault. Check the fuses and replace as necessary.
Engine coolant level too low.
Check the engine coolant level after the engine has cooled down and add engine coolant if low. If the engine coolant level is correct or the problem continues after adding coolant, do not drive any farther. Contact an authorized Volkswagen dealer or authorized Volkswagen Service Facility. These instructions apply only when the coolant temperature stays in the normal range.
Engine coolant system malfunction.
² Stop! Get assistance from an authorized Volkswagen dealer, an authorized Volkswagen Service Facility, or another qualified workshop.
– – Do not drive at high engine speeds or with heavy engine loads until the engine warms up.
When the ignition is switched on, several warning and indicator lights come on briefly for a function check. They go out after a few seconds.
The engine coolant temperature may also be shown in the Volkswagen Information System MFI display, MFI menu (Multi-Function Indicator). On some equipment versions, all symbols and information in the display are shown in red, Displays and warning lights (Basic version). The red color of the letters, numbers, and symbols used in the display does not indicate a malfunction.
The ideal operating temperature of the engine can vary and depends on the driving situation. If the engine coolant temperature should get any warmer than about 198 °F (95 °C) the MFI display will automatically switch to the digital coolant temperature display. If the engine coolant temperature is already being displayed, no change will occur. This, however, is only informational and does not indicate overheating.
If the engine coolant temperature is too high (warmer than 257 °F or 125 °C), the red engine coolant temperature warning light on the fuel gauge in the instrument cluster will flash. An acoustic signal may also sound.
