A few months ago I had the 801225 - "Compressor: shutdown due to negative pressure in the refrigerant circuit".
Took to a garage chain to have it checked out and they said the couldn't find a leak and topped up the refrigerant and all was good.
Fast forward a few months and I'm getting the 801225 again. I'm guessing there is a slow leak, so I purchased -
A/C Pro digital trigger and A/C pro A/C recharge (that seals small leaks).
However when I connect the A/C Pro digital trigger it reads 0 PSI, I assume it's one of three things -
1. Looking at the connectors I suspect it may not be fully connecting - assuming the pin needs to be depressed in the car fill port?
2. Showing 0 PSI because the compressor is shutdown?
3. It is actually 0 PSI?
I connected up the refrigerant can to the trigger, connected it and as soon as I pressed the trigger it came up with 60 PSI, I disconnected it and the trigger still showed 60 PSI, pressing the trigger (when disconnected from the car) it hissed and went to 0 PSI.
Any advice / guidance would be gratefully received
