Can any one tell me where the G395 A/C Pressure Temperature sensor is ,as I've just done a Re gas on my (B8) 2008 A4 2.0 TDI & it threw up all sorts of codes referring to this part. After the Re gas the air con is still not working. I have also found on the net a Technical bulletin from Audi referring to this being a problem with the A4, A5, & S5 as there is also a LIN (Bus Data) cable that connects this sensor to the control unit that may get pinched / broken. Has any one heard of this happening ??
