My air con was very erratic but after advice I replace the temperature control valve motor and it now controls the temperature hot and cold just fine. This also cleared the fault code, I still have a recirculation quality sensor error but I don't think this is relevant. However, on the coldest setting, sometimes it blows properly cold and sometimes just the ambient temperature. It's been gassed and checked for leaks but is all OK, it seems possible that sometimes the compressor doesn't run. I have the HVAC manual and there are lots of possible reasons for this but I don't really know where to start. Any further advice greatly appreciated as summer approaches. Pete

Air con faults
Pharris_uk replied to Pharris_uk's topic in 9PA, 9PA1 (Cayenne, Cayenne S, Cayenne Turbo, Cayenne Turbo S)
On a right hand drive car the left hand motor control valve is very easy to get to, the right hand one is tough and involves removing the foot brake assembly. Garage charged 3 hours labour. The heater core assembly is also not easy to come by in the uk but individual motors are quite cheap, hence I only did the one motor that I needed. Temperature is now properly controlled hot and cold, but I'm about to post another question as it only blows properly cold intermittently, often is just ambient cold. Once again, thanks for the help though. -
Air con faults

I am looking into this, thanks very much for your reply Brett. -
Hi, have recently bought an 03 Cayenne turbo with many faults, currently I am trying to sort out the air con / climate control. It does odd things, the temperature usually doesn't adjust as asked, sometime there is hot air and cold air coming from adjacent vents. It's been tested for leaks and gas. I have errors 1810 drive motor for temperature valve right, 2100 footwell flap and 1592 air quality sensor. I have seen other posts that makes me think it is worth replacing the motor relating to the 1810 code, but I am not sure where it is. Please can anyone help?
