you could try gently releasing the pressure when hot , then when you get to your destination try again and see if any further pressure has built up ..

Is Head/head gasket failure on these a thing then? Thought the d5’s are bullet proof? Only 5 years old aswell.
Is very strange. If I start the car from cold and run it for 5 mins then turn it off and check for pressure there is nothing there. Only when its been run up to full temperature does it retain some pressure.
