That's kind John but I'm going to leave this one to the garage, and I'll probably call on you for the water pump and stat at some point so don't want to take the p155. I'm already resigned to a few hundred quid going on the credit card in the next few days.
Indeed! I've just found the garage receipt. Paid £554.40 on 06/05/2016. The pump itself was £372. Do peeps think I have any recourse? I guess not as it's three years and one month ago. If so though, I might enquire who the supplier was at least just to help other folks out on avoiding poor parts.
