Hi, I know this has been covered before but I've got a compounded problem. Coming back from holiday all was fine......in a real rainstorm then suddenly ALL heating was lost......only cold air. To cut long story short. Everything else on the car is fine. Local Auto Electrician ran a diagnostic which showed FIVE fault codes:a/C Pressure switch / footwell defroster flap positioning motor / positioning motor for temperature flap / Air flow flap positioning motor / Diagnostic Interface for Data Bus. I know these can go wrong but ALL together and ALL at the same time? Could it possibly be the climatronic unit itself sending out "duff" info.? I've been told the horror stories regarding costs etc but otherwise this car is great - the best I've ever had and I've had this one almost 15 years now so would be really sad to see it go to scrap for such an apparent / trivial yet crucial malfunction. Anyone help? I've located a second hand climatic unit so I'm gonna at least try changing that. By the way I wish I'd know earlier of the simple two-button self diagnostic on the climatronic.....it showed the same results as my "auto-electrician" expert......and he charged me £40 for the info.
