One of my customers has the above Vectra, he has reported a sudden loss of heat from the heater, I have tried draining & vacuming out the system then refilling, for a few days it's perfect, then suddenly the heater either goes warm or cold, vacum it out & refill it & same happens again, replaced the heater valve, still the same, replaced the thermostat (not fully opening) still the same, they sent it to someone else & all was well to start with & now we are back to square 1, anyone experienced this before or any suggestions
