Sorry to resurrect, I’ve paid my donation so have access to the bleeding instructions. I also have access to diagbox to follow the instructions. Just wanted to check in interpolating the instructions correctly. The bleeding is done with the reservoir cap off?

Is this really a thing? I've just done a cam belt/water pump on a 2.0HDI and just filled it back up until the expansion bottle stopped draining into the engine, temps are exactly the same now as they were before I changed the water pump. Surely any air will work its way back up through the water and back out to the atmosphere, especially with a pump pumping it round everywhere.

I have also recently done my 1.5 Blue HDI, Filled until it came out of the bleed screw on heater hose, which was the highest point, Test drove and topped up to max. Just done a 3000 km trip and no problems and no change in coolant level. I also have a vacuum bleeder but never needed it. It is not rocket science.
