Question for everyone here ... my 2006 T5 3.2V6 6sp Auto - A/C Compressor has failed.

I can't seem to find any compatible one online ... is that because they are listed as something else?

I found a Valeo 813419 one, which says its compatible on some sites? But I have no idea. Are the petrol and diesel ones the same? It seems a bit of a black art trying to find a part number that is relevant to replace this one.

Any help appreciated.
