Hello,
I have faced the same issue an my 190 diesel kodiaq L&K.
Even if the external temperature was between -5 and 0 °Celsius, the water gauge was at 130°
Just switch on the AC and the Fan helped to join the 90°
After that i have driven 500Km in one time with no issue.
I have faced again the issue 3 or 4 times, each time it was when the car was cod and after 10 or 15 km. Each time the temp was OK again after activating AC and FAN.
I have asked skoda dealer to fix the issue, but they say that they are not able to reproduce the problem.
They ask me to wait a hot temp engine message.
For me it's incredible to ask customer to drive with temp at 130° waiting for an hypothetic alert message (I have the photo of the dashboard where you can see the temp at 130°)
I have deal with the garage to give them my car for one week, so they will be able to test it when the car is cold.
I just hope that the ambient external temp, (now near 10° in France), will not be a case of non-failure .....
Kind Regards
