hi guys and gals recently my climate control has had a mind of its own and a funny rumbling noise from the heatre it is duel zone on a 54 plate octy it seems to work for ten min or so then starts blowing hot air . any help would be apreciated as a new heatre control is well over £500 i dont know if it is fixable way a software update or if it is just knackered

I had that funny rumbling noise from my heater, it was the start of no air con. Main reason is low gas pressure, I think.

Dont think it is the actual heater control (Climatronic )

There are posts on how to get the fault codes through the climate control panel . Use the search for air con
