Instrument overview
The following table explains what to do if the engine coolant temperature warning light
out a few seconds after the engine is started or starts flashing while driving.
Flashes
Possible cause
Engine coolant temperature too
high.
Engine coolant level too low.

malfunction.

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.
Proper response
Stop!
²
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.
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.
Stop!
²
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.
