Doing some checks on the 2014 CLS 63 today, the iCarsoft check on the aircon pressure (must be high side) never rose above 10.2 bar (just after I cranked it down to 16 degrees from 20) and dropped quite quickly to about 8 bar.
It takes a lot longer, because it doesn't blow nearly as cold as the CLS 350's almost-instant instant Arctic blast, to get the temperature down. ISTR the W210's aircon, with built-in OBD, ran at something like 14 bar.
There were no fault codes. Does anyone know whether the pressure readings I obtained indicate the system is low on refrigerant?
