Thanks for the reply Del (btw is there just you and me on this forum or what?

)
I've read a few stories about non-genuine cables, so I won't go there, especially after my recent bill of £1100 for a brake calliper and nearly the same for the pump if it had gone back to the indies/dealers.
Was just looking on ebay and some people with 100 per cent positive feedback have got their genuine cable for sale, question begs; is it worth a punt buying a 'used once' or is it better to get it directly from the reseller?
is the registration transferrable?
I want to get one now, since I need to be able to rescan after fixing the compressor, and also would like to check the other problem I was getting which has caused the EML to come on.. something to do with the manifold flaps and the plastic arms that control them..
