Managed to do mine this afternoon after finding the correct torx bit in my toolbox. Was in the same state as yours craigblues but managed to get it as clean, didn't file the flap either as copperknob advises as it seemed ok and moved freely. I also scrapped out the crud from the manifold as that was quite bad too. while i was at it, i fitted a blanking plate to the egr valve as that arrived yesterday via fleabay! Haven't taken it for a spin yet but it definitely idled better and smoother then before as it was a bit lumpy when cold.
