E430 Air Conditioning. Low pressure port
Hi Guys,
I just picked up my (new to me) E430 yesterday and the air conditioning is not as cool as I think it should be. I have a pressure gauge and wanted to check the pressure. I took a quick look and couldn't really see where the low pressure port is. Any help directing me to it would be appreciated. Thanks.

As pressure difference shows, the compressor is working, just not building pressure.
You can do full system check per links in other topics, but if another test shows the same pressure difference - you need new compressor -usually coupled with new drier.
What you want to see with compressor set to max is 2 -3 bars on low side and at least 17 on high
