I am happy to say that my heater is now working fine after several new parts.
obviously the first thing checked and replaced was the thermostat.
then we went for the heater matrix only to find it wasn’t blocked.
next the garage looked at the heater switch which works the flap no success and then they looked at something I didn’t even know existed and that is the water pump for the heater. Yes apparently it has a separate water pump, well that’s what I was told. Anyway it is now fully functional
