Air Conditioning Issues 4.2 V8 S-Type

[Matt9711]

When I bought the car the heater valve had taken out the CCU so changed those and didn't bother with much else as it was cold. Today due to the warm weather I had it regassed but it didn't work. The guys hooked it up and the car gave 9 climate faults and 6 engine faults. After clearing the faults down only one climate fault remains B2516 Blower Motor Control Circuit Failure. The ECU Faults remaining are:

P0533 Air Con Pressure Sensor A Circuit High

P1260 Security Input

P1582 Flight recorder date is stored

B0300 Network Management Expulsion

B1316 Boot/Trunk Latch Power Close Unit

P1111 System Deck Complete (I think)

Its only fair to highlight that I have the Fibre optic cable out of the boot at the moment, so voice, nav, cdc and phone are not connected.

I am assuming that I need to get a pressure sensor "a" and repair the blower motor (which is odd as it seems to operate at all speeds)?

Your informed thoughts are appreciated.
