i have a 2000 A4 TDI 110 Pk
Now when the weather is getting colder here in belgium i noticed something.
The other day i drove about 12 minutes and the engine temp meter got about
the first line (+/-40°C)
the i had to wait for my friend so i kept the engine running stationary with
the heating on. i saw that the temp dropped in stead of getting higher.
Is it normal that the engine takes so long to get on temp? and is it normal
that the temp even drops when running stat. with the heating on?
can it be the valve that circulates the cooling fluid inside the engine
first en when on temp it goes open to circulate trhough the radiotor? how do
i check this?
