Take to kwick fit, they have a no fill, no charge, system going on.
Kwick fit try to fill it up.
First off, the system is vac'd. Then, a pressure test. If it passes the pressure test it can be filled and you'll be sorted.
If the car fails the pressure test (which it should), then they will run dye through it and identify which element is at fault. Leave without paying a penny as you don't want to pay them to do the work.
Once they've identified this element, go to Cliospares, buy a replacement, fit it yourself, go back, and pay to have it filled.
