Hello,
I have searched this forum but didn't find an answer to my question.

I have a 2002 A6 4.2. The econ light on the climate control will come on and stay on about 5 minutes into driving, meaning I have no A/C. I had the car VAG'd today and here is the fault:
00819 - High Pressure Sensor (G65)
29-00 - Short to Ground

I found the following article on Ross-Tech:
http://wiki.ross-tech.com/index.php/00819

The recommended solutions are:
00819 - High Pressure Sensor (G65): Signal too Low
Possible Symptoms

* Climate Control stuck in ECON Mode

Possible Causes

* Insufficient Refrigerant Pressure
* Wiring/Connectors from/to High Pressure Sensor (G65) faulty
* High Pressure Sensor (G65) faulty

Possible Solutions

* Check Refrigerant Pressure
o Check Measuring Value Blocks (MVB)
* Check Wiring/Connectors from/to High Pressure Sensor (G65)
* Check High Pressure Sensor (G65)


My question is:
Should I have the system checked for low refrigerant before replacing the sensor? The 29-00 Short to ground from the fault code makes me think the actual sensor may be bad. Has anyone had this same code before? Any suggestions?

Thanks in advance.

I'd say yes. Have the system checked.
