My volvo v40 has been running fine since I bought it in August 2020, I've even driven it to London and back.
Ever since my service I have had problems, firstly coming up with low level coolant.
I read up on this and purged the system incase of trapped air, there was alot of pressure in the coolant tank when I removed removed cap at first.
After this the low coolant message stopped, but not i have 'engine temp level high, slow down'.
So I've taken it in to the local garage, I've had the water pump changed along with the thermostat and due to these the timing belt.
I no longer have heat in thr cap neither, my coolant is clear, my exhaust fumes are fine.

Can any one come up with ideas of what's going on? Suggestions please?

High pressure in the cooling system is probably a crack in the head gasket.

Which year and model is your V40?

For some early 1.6 gasoline model, you have the following recall for low coolant issue:

Volvo "Coolant leakage may result in a fire" Recall - V40 V40 CC S60 V60 V70 S80

It has been identified that during the engine warm-up process and under certain driving/climate conditions, for instance periods of high acceleration or high engine load immediately after a cold start, in cold climates, there is the possibility for coolant leakage or oil seepage. This can lead...
