Airconditioning
Hi All.
I have hot air from my AC system.
The car has had dye put in it "sticker in engein bay" so thought it must have had a leak.
I vacced it and it pulled down so the leak cant be a big one.
I then re charged it with 134a 30g but when running the system looked under charged by pressures I was getting. Then put some more in however it keeps pumping down on low side? Like there is a blockage. I see a thread with a similar issue but there seems to be no resolution?... from 2009.
Does anyone have an AC schematic for C32 amg system?
Its like the exv or reverse valve or something is stuck closed... the compressor should be OK becuase its pumping the system to vac/low pressure.
It was 36 here yesterday! I need AC! :-)

All good, found the HP and LP connections, re charged with approx 750g of 134a, ... HP was under a flap RH side of vehicle radiator.
Cleared all errors with an excellent tool, I would recommend this one for european cars if you want to clear codes on all modules and see codes for only $200 I picked one up. Max price is $350. If you want to view sensor outputs, re calibrate sensors etc you need to spend more money.. $1000.
The one i am using is AUTEL MAXI-ELITE MD702. good value for what it does.
