Hi Gareth, thanks. Me too, it did cause me a bit of a headache initially but with a bit of research and various testing I got there in the end, thankfully at not too much expense.
It's always good to try and help someone out if they're having the same problems so hopefully some people will benefit from this post.
I don't see the point in saving just a few pounds if you can get genuine parts at affordable prices. They're generally better quality and with the likes of sensors which work on very small tolerances it's a must.
Cheers
James
