Sorry to hear your respective continuing issues.
My heater is working, temperature gauge is normal (constant 90 degrees) and all warning lights have gone. So, on the face of it, mine is fixed.
However, given the issues we've been having, I have been checking the radiator and bottom hose after both short trips and long trips (including stopping at motorway servcies mid journey). Every time, the bottom half of the radiator and the bottom hose are completely cold - not even luke warm.
I've reported back to my agent and they are working it through with INEOS.
This could be down to the ambient temperature and the engine not needing to be further cooled, but I'm sceptical.
Could I ask that others do a similar check and report findings here. It would be helpful if someone from warmer parts of the world could report whether their bottom hose is getting hot.
