Thanks for the reply, has confirmed my thoughts I needed a H suffix slip ring, will now watch ebay.de to wait for one at the right price hopefully before the winter starts!!
I got a wheel, with cowl and switch for €165 which I'm happy with, the slip rings seem to sell for between €40 and €150 depending on the seller, so happy to wait for the right price as I certainly don't need heat in this weather!!!!
Looking at the wiring diagram, I may need to run a wire from the switch to the control module if it isn't already in the loom, that aside looks like pretty much plug and play.
I've never been able to work out how to get a part code based upon PR code, so thanks again
