    Just interested if anyone else get this. Very occasionally when I start her up the HVAC panel shows complete nonsense where it should show a temp and bars missing where it indicates fan speed. when this happens if I switch ignition key off and then switch back on, so reboot the system, the readings on the HVAC display resume to normal. Is this something that e.g. stabilant 22a may sort?

    Sounds as though you are just going into the A/C diagnostic mode, which happens when you hold down button 13 as you turn on the ignition.

    Perhaps you have a stuck button on your A/C panel?

    Thanks for that NoDoubt, I'll have a fiddle with switch 13 and see if it makes a difference. Doesn't happen every time so make take a while to assess if its a fix.
