Thanks stimulator
Yes it is auto aircon, and the display shows A/C when the button is pressed, tho no click from compressor or change in engine idle.
Hmm - wondering if there's two faults here: 1, the compressor not kicking in, and 2, the aircon flap/motor.
So...:
1: is there a way of manually actuating the compressor - a relay or connection somewhere that will actuate it to test it?
And
2: Anyone know how to even get at the flap actuator motor to test that?
Thanks again
Jay

In my opinion, the heater flaps may or may not be working correctly. But they will not prevent the A/C compressor from kicking in.
The fact that the system was regassed is the clue. Unless whatever allowed the previous gas charge to escape has been fixed- the new charge will also leak away. You need someone who can detect the leak- and that will be A/C specialist territory. Kwik Fitup will tell you their machine senses leakage- but it will not detect a slow leak, only a sizeable loss over around 1 minute.
There are 3 flap/motor assembles. They can all be got at after removing the lower centre facia- just about!

Hi. I had to change the engine cooling fan on mine, not a big job just expensive and a fairly common thing on the 1.6 HDI.
Try the free stuff first, with the engine running is the engine cooling fan working when you switch the aircon on?
If not try to get on a quite road at about 30mph switch on the aircon and see if it blows cold, you will need to maintain 20/30mph for a few minutes to keep the airflow doing the work of the fan.

Hi. Just found the thread that helped me repair my a/c, maybe of some use to you.

Thanks to all who posted suggestions trying to help, sorry it's been a while getting back to update you, had ISP problems.
Anyway, the car's now been fixed , turned out the problem was a v-e-r-y s-l-o-w leak in the evaporator, which has now been replaced (free of charge!) So lotsa nice frosty air, which has been very welcome over the past few warm days.
As you surmised stimulator, the knocking appears to be being caused by a divertor flap, which seems to struggle a bit but gets there eventually. So as you said discv, it may or may not be working, but not the cause. Looking at the work required to get at them, I think this'll have to wait for a day when I have much more time available than lately.
Thanks guys
