Amazing to see Crasher still on here all these years!!!! Top Man.

Yes, still here, a bit like an irritating rash you can't get rid of. I haven't done it but I have heard using the none variable displacement pump can cause problems and on certain engine such as the CUNA they are almost impossible to fully bleed with a vacuum filling system and a specific computer bleed process so around 2L of water volume air stays trapped inside the system and travels around causing hot spot boiling and overflow.

What is the VIN? The CUNA code engine is the worst for this.

Yes it has the system which is near impossible to bleed without ODIS and a vacuum system. I find even VCDS cannot initiate the bleed procedure ODIS can.
