Hi. Bruno. Thanks for reply, just to clarify, are you saying that the matrix is different from standard non aircon? or only possibly , as I think you are saying that when yours went it was a standard one? should I go for the golf one? Where is the internal temp probe and how do I know if its in the wrong place? So if the matrix fails does the aircon dump all its gas? Can any of these questions be answered if I print out the Diavia Aircon thread/ Sorry to bombard you with all this,don't know too much about aircon yet,but I am an engineer so cant be to difficult? Cheers Purplebaghera.
