Sorry For the delay in getting back with an answer folks BUT good news, I have finally sourced all the items for the plug. All sourced from E Bay, from the seller: Pantri Trading, I had a fair number of exchanges with them which I must add was positive and helpful. The prices quoted do seem steep but they are open to you making an offer. If there is not sufficient stock they will source and let you know.
Attached hopefully is a photo with the required parts, the numbers I am lead to believe are the BMW part numbers and they relate to the E Bay ordering.
I hope this helps people, I am hopefully finishing the loom change tomorrow evening. It has been a bit of a headache but the results mean I now have a good loom which should last me out ... Hopefully
Anything that I may be able to help with please ask.
Cheers
Spud
