Flushing Debris From Air Con System.
Discussion
My 2013 XF 3.0 Diesel S has a failed A/C compressor. In the process of failing it may well have ejected swarf or other debris into the system's pipework, so just fitting a new compressor is likely to be waste of time and money. Does anyone have any experience of having a system flushed to remove debris?
I suspect you might be overthinking this. A failed compressor is a fairly common cause of a non-operative A/C system and as it is an electromechanical device the failure is seldom related to its internals disintegrating.
When an A/C system is breached in any way (either due to a leak or repairs) as a matter of course it is vacuumed out (and a new drier fitted) to remove all moisture and contaminants before being refilled with gas and lubricant, so in the very unlikely event that anything had physically strayed into the pipes this would remove it.

In all honesty flushing the system won't remove all the debris.
Replace the compressor and the receiver dryer, which has a built in filter.
Most, if not all of the debris will be found in the condenser radiator, and the receiver dryer should have stopped the rest before it got to the expansion valve.
