Thanks, I've actually already been to the dealer and ordered the part for £10 plus VAT, they estimated £30 + VAT for painting so you are spot on. I just thought I'd see if anyone else had had the problem, since if I can save myself a few quid I may as well, as would anyone. Especially as there are some who have had this problem have also had the jets need replacing as well due to the same issue, which is not cheap. Luckily it just seems to be the cover with me.
