I’m getting my 2007 air con re-gassed and I was wondering how much R134a the ?hp takes. Could also do with knowing if this takes PAG 46 compressor oil and the quantity please.

The question suggests you are planning to regas it yourself. Not a good idea.
Take it to an aircon specialist, (actually most garages can do this now). They have the equipment to extract the remaining gas, then do a leak test, and regas with the correct quantity of gas and the correct oil. Their equipment supplier will supply them with teh specs for each car. Usually you only pay for the additional gas used.
The gas is harmful to stratospheric ozone (though less than the old CFCs) and is a powerful global warming gas so should not be simply dumped or topped up without leak testing.
Fridges are now using butane. Who knows why cars don't.

It's both extremely volatile and extremely flammable. You wouldn't want a ruptured aircon line spewing butane over a hot engine in the event of a crash. There are probably a shedload of other good technical reasons, but that one will do for me.
