FYI, the pressure switch on the Golf (could be different on yours) cannot be bypassed, as it sends a duty cycle rather than a ground or voltage which cant be imitated really.

You are best getting it regassed in the 1st instance, then 2nd replace pressure sensor. You could put 12v to the compressor to test it, but if there is no pressure in the system you could end up damaging it and they are the most costly of components.

Kwik fit have a "if it doesnt work after we have regassed, no charge" policy. Maybe worth a shot?
