I have an air con prob where by it doesn't blow cold anymore, I hear the fan noise increase when I turn it on though. I took it for a re-gas but was told it was okay, I just took it to a stealer & was given this report:

B1227 Exterior temp sensor B10/5
B1231 Coolant temp sensor B11/4 comes from engine control module
B1416 Heating water circulation pump A31m1
B1422 Serial interface K1 from inst cluster to AC control module

But they don't know why it doesn't work, any ideas anyone??? Apparently the pressure is 8 bar...[/align]
