The temp sensor on the bottom of the condensor and connecting plug had rotted away on my C32 and consequently the compressor would not engage.
After poring through the EPC I found the numbers for the parts to repair the plug.
I replaced the old sensor with a new one. Mine was a 4 pin even though the EPC said 3 pin.
New sensor: A203 830 0472
The new plug socket is A210 540 4381
New wires: Cable harness A000 540 2405.

The wires need to be inserted into the new plug. Fairly easy with long nosed pliers and patience.
The wires were the spliced to the old loom using heatshrink solder splices (red) and heatshrink tubing over the top.
The lead is now longer than it was so it was easier to route the cable.
Plugged in and air-con burst into life :bannana:

Hope this info helps somebody else out there.
Tony
