Out of the blue, my air con stopped working (Econ light on permanently). I read the threads on this forum - (which were very useful) and did a VAG COM. I was getting an 00819 high pressure sensor (G65) warning. I tried clearing it but it kept coming back, then whilst doing the measuring blocks, the light went off. These are the readings I subsequently got:
Absolute Pressure 5%
Can anybody help me to make sense of them please i.e. is the absolute pressure referring to the refrigerant, and is this OK?
I'm trying to work out whether I just need a new sensor or a re-gas (or both).
The car is an A4 avant 2004 1.8T S Line
Very many thanks in advance.
