Popped in for a replacement part for my jet wash pressure hose at my local HalfordsPopped and came out with the air con re-gassed and cleaned for £34.99. They refunded me the cleaner spray and normally give you the air con bottle which you get £10 back for the next time. Took about 30 minutes when I showed the guy where the air con valves were after seeing a post on the forum.
I'm a chilled happy dude!
