I would recommend you call Aircon Direct - 01474 832941 or 01634 420320 - http://www.ac4cars.co.uk/ Tell them Rover Matt who currently has a BMW Z4M recommended you call them.
I have used this company for 15+ years on many many cars and they are absolutely excellent and very reasonable. They come out to you.
Forget Kwik-Fit and the dealers, these guys are specialists in car air conditioning systems. They know all the tricks, weak points in various systems and have all the specialist gear, etc.
Car air conditioning is a specialist area and you need specialist knowledge and experience to be good at it. Kwik fit can gas a system up but if it is a leaking system, it will work for a while and then stop when it has lost it's gas again. Worse, they may gas up a leaking system which is low on refrigeration oil and on a hot day, your AC compressor will cease up and spit metal fragments all around the other delicate AC system components.
They may find a leak and if you want to change the faulty component yourself, they can help you source a replacement at preferential rates through their trade contacts, give you advice and go away so you can fit the component and then come back to test and gas it all up. Or they can do the lot for you, your call, they will work with you and help you get it sorted.
