My A/C is cooling, but wanted to see if it needs to be topped off.
Hooked up gauge to low pressure line on 2000 430CLK. Gauge is not reading any pressure.
Tested/connected gauge on 1997 BMW Z3. Gauge does not read pressure.
Tested/connected gauge to 1993 Jeep ZJ. Gauge reads good pressure.
Gauge reads pressure on American, but NOT on German cars.
So, is this a German thing?
Do I need some special fitting, or what?
Thanks
Note: All cars, CLK, Z3, are blowing cold air--have good a/c units.

You could determine ur Freon charge level thru this. If it comes back ok then dont top off your freon. Overcharging could lead to stuff bursting. You dont want that.
