Use the hidden menu or some form of live reader to see what the actual temp is.
Do you have cabin heat and what is the ambient temp? You might have a temp sensor fault.
You can use an IR thermometer to measure the upper radiator hose to measure engine temp.
New ≠ fixed. You can do some testing such as block the radiator with cardboard see if it'll warm up: indicates the thermostat stuck open even though new.
A defective temp sensor can cause the non gauge needle on the dash to stay low but if the sensor is at fault you should have a hot hose and cabin heat.
You can clamp a radiator hose to simulate closed thermostat. If the temp climbs fast means you got a defective new tstat.

So, i do get warm air coming in. Nothing that i would say is 'heat'.
I can drive around and eventually after 25 minutes of driving i get hot air in the cabin.
The temp gauge needle is so reluctant to rise to the noon position and takes for ever.
We live in a small town where you can drive from one side to the other within 10mins... so waiting for the car to heat up is pointless lol
Also, the reason why i changed the thermostat in the first place was because i thought that it could have been faulty and this is why the temp was not rising.
After changing the thermostat i am getting the same results as before, so i think that my previous thermostat was fine.
I will check again today, as we are expecting a cold patch of weather next week.
Thank you
