Hello,

I have a fault appearing on my 2007 3.0 TDI Q7 AC.

the error is showing a fault with the Refrigerant Temperature Sensor where is this located exactly please??

Has anyone any diagrams or first hand knowledge??

thanks in advance

Hello Andy,

Can we take I your air conditioning isn’t working?

If so, there is a recent -ish thread on here relating to the air con pressure switch ( not temperature though) which is said to be located on the condenser. Not sure if this might be what is the issue, but reading the thread (A6?) might throw some light on it. 

Kind regards,

Gareth. 

Thanks Gareth!

ill take a look shortly.
