2014 639 Viano- 651, 5sp Auto. 2009 S211- 646, 5sp Auto.
ATS pressure tested with nitrogen and all good.
The machine went through its cycles and recharged the gas to 850g.

No AC. The HP reads 8 bar+, does that indicate the compressor is functioning?
The LP was approx 5.5 bar and pulsing.

They recovered the gas so at least I can strip such as the pressure switch off w/o losing it to atmosphere.

Any thoughts?
