Gareth,
Yes, I can post these images for you if you send them to my email. I will send you it as a personal message from this site. I have not had a MAF sensor fail in over 5 years of S1 ownership. There has been quite a few others that have had that problem. They do come a lot more expensive than the £25 you quote. Someone highlighted a cost of over £100 and that didn't last long.
