Mine has told me off for leaving it on the drive and going on holiday for a week by presenting me with another SRS light
Possibly, but gut feel is software/logic.. but i suppose that's impacted by hardware ie bad connections and the expected signalsAnother "quality" connector corroded somewhere
It was blowing icy cold just fine in the summer but kept misting up last winter too so it's not gas level.Has it got enough refrigerant in the system? do the recirculation flaps open & close properly? is the pollution sensor defective?
Does the outside temp sensor work kermitude?It was blowing icy cold just fine in the summer but kept misting up last winter too so it's not gas level.
You can hear the recirc flaps move and the change in blow noise so assume they work ok.
Pretty sure the pollution sensor doesn't work because it doesn't do anything when set to auto so i leave it switched off
It shows the correct temp on the dash yepDoes the outside temp sensor work kermitude?
It could still be refrigerant (not gas!) level is low as the pressure is temperature dependent. Refrigerant needs to change state from liquid to gas and back again to work, if there is insufficient quantity to do this, then the pressures to force a state change cannot be generated so you can end up with gas only in the whole system in cold weather and gas & liquid in hot weather.It was blowing icy cold just fine in the summer but kept misting up last winter too so it's not gas level.

Do you mean that on order to check, you need to evacuate and recharge the system, not just measure the pressures? I assumed the machine they plug in would take ambient temp into account.It could still be refrigerant (not gas!) level is low as the pressure is temperature dependent.

This is why refrigerant systems are charged by weight, not pressure.
The only other things that come to mind are the air vents at the rear (to draw air out when moving) are blocked or restricted - or you have water ingress.
