That said, the problems are much easier to solve when you have the proper symptom diagnoses: in the case of AC it's nearly pointless to work without measuring both high and low pressure

If your referring to the "if your x5 takes forever to start cooling but cools find till it sits overnight again" then yes its 100%. This has been proven time and time again. I posted to fix for this a few pages back.

Also gauges are useless for this fix since its a variable compressor and doesn't do anything till its internal valve gets "in the mood" to allow it to compress anything.

So as I and others have said over and over if it takes a long time to ever start cooling and then starts cooling and works flawless all day till you turn the car off and let it sit over night its the compressor that needs replacing 100% of the time. No if ands or buts on the X5's.
