So I had some luck on eBay sourcing an alcantra MFSW for my DTM cost me Ł80 I also picked up a Slip ring(4E0953541B) for Ł65 from ebay.de I already had SCM(8E0953549Q) fitted not sure if it was the correct part as people have recommended part number (8E0953549R) so I took a gamble. All fitted, coded and working like a dream.
Total cost Ł145 Bargin!!!
Ooh and for the record SCM 8E0953549Q works !
I retrofitted one too (ebay is great ) and I have to say I would be a bit lost without it, it gets used everyday and is a great retrofit.
