Question

Post by henrym3 » Thu Jun 26, 2025 9:15 pm

Was fiddling with the heater controls yesterday and had set them on 22c but no heat came out. Used diagnostics and found that the heater valves didn’t open to 25c however the interior temperature was showing as 23c. Is the opening temperature somehow linked be module/computer as to what temperature the valves will open. Only had the X for 10 years and never came across this. When the valves did open heat came out.
