02 W208 CLK is hiding freon when car is not running. Pressure on start up is to low to engage compressor. shows 7 bar on climate control screen display. Once I reset the system either on the panel or using carsoft It starts working and shows 13-14 bar! When I serviced it I used R134a with dye. After using a vacuum pump to evac it it held the vacuum, got it running, checked everything with black light no leaks found,very cold AC when running and gauges look good when running weird
