Default Maybe....>

Unless it's caused by a mechanical problem (water pump or thermostat). What are the temps on the HVAC block 49 readout?

Default You should be OK with that fix, but...>>

Check the temps digitally with the HVAC controls..No Vag necessary:

Press [Recirc] and [Up arrow] buttons together. Use left 'temp' control
Dial to 49. Press [Recirc] button again to display value. On average, normal operating temp is around 90 (degress C)


To return to HVAC controls back to normal, press [Recirc] and [Up arrow]
buttons together.
Display should return back to temperature control/display.

Default If the car was fully warmed up, that's low.....>

Which would point to a thermostat problem, but replace the sender first and check again before going further..
