With "working compressor" do you mean the levels while the engine/compressor is running? And "stuck" means engine/compressor off?
Any chance you could explain what the last sentence means as it flew right over my head?
Ok, my English is poor...
Especially technical English it is for me
terra incognita.
So:
"With working compressor" it means AC switch is on and AC works. At the same time compressor starts and stops in appropriate periods.
"Stuck compressor" it means AC switch is off and AC doesn't work a couple of minutes (minimum 10-15 minutes or more). It is time, that pressure on LS and HS should be the same on both sides.
-------------------------------------------
"It is typical pressure for AC with flow nozzle (without expansion valve )".Are two basic AC types: with expansion valve (most popular in cars) and with flow nozzle (this one is in Transit MK6).
"(and compressor with constant swept capacity)".Are two basic AC compressor types:
- variable displacement volume compressor, it works whole time if AC is on, so pressure changes are small,
- constant displacement volume compressor, it works and stops in short periods, so pressure jumps down and high much more. This second one is in Mk6 AC.
-------------------------------------
While very high outside temperature (+35Cdeg.), pressure on HS is also higher - it can be 18 - 25 bar (261 - 360 PSI).
