Aircon intermittent

[Targa27]

Hey... hope someone can help. Have done a quick search and cant seem to find a similar issue so hope im not repeating here.

Collected my RS4(B7) 2 weeks ago and already have an issue
The aircon suddenly stopped working, with the ECON button always illuminated. This was intermittent at first but never recovers now.
I invested in the Ross-tech lead and software and have found the following fault:
00819 - High Pressure Sensor (G65)
29-10 - Short to Ground - Intermittent

Does anyone know where the sensor is located? I would prefer to check the connection myself and even replace myself rather than go to an Audi dealer.

Thanks in Advance

Can't answer your questions I'm afraid.... but did you buy your car from an Audi Stealer ?
You have 30 days money-back to wave at them... if you did.

Good luck with sorting it.

Sorted it... wasnt as bad a job as I had expected.
Firstly I have a 3mth warrenty but I am a long way from the seller and cant do without the car at the moment.

I was able to buy a high pressure sensor from my local Audi garage for £52, came home, removed the front bumper and fitted the new sensor (which is located under the passanger headlight, screwed into a pipe on the end of the aircon rad)
The sensor is a dry-break type of fitting so no loss of pressure.

For those with Vag-com, the sensor was failing off high, (100% High pressure signal and 33bar refrigerant circuit pressure)
The new readings are 28.5 % High-Pressure Signal (G65), 8.0 bar Refrigerant Circuit Pressure

Hope this helps anyone else with a similar fail code in the future.
Now back to enjoying my new toy!!
