You have an air park brake? So if you have the version with engine driven compressor as opposed to the electric compressor, it could be the head gasket on the compressor that is starting to leak. you will need to see if air is coming back from the air tanks into the cooling system with the engine stopped.

Then it is probably the head gasket, however this is not a common fault so I would test the gas in the header tank to make sure that it is combustion gasses and not just normal expansion.

Interesting stuff this, particularly if you know noting about these things

Look forward to more on this
