DIY A/C refill

[Dave_ST220]

I decided to top up my car using this kit :-

Appeared to work fine. However now when I switch the A/C there is a vibrating noise for about 3 seconds, looking under the bonnet the A/C pipes vibrate when first switching it on, rest of the day and any subsequent restarts it's fine.

Any ideas? Poor quality gauge so now it's overfilled?

I've contacted the seller who said they've never had problems, also contacted the manufacturer who haven't even bothered to reply!

TIA

There are no leaks (I understand these systems leak the gas but rarely the oil). The top up claimed to have oil & gas in it.

£69.95.

How much would a proper job using proper kit have cost?

ETA Quick google suggests from £60ish is the going rate local to me (Leicester)

Everywhere around here was quoting £99, + a wait & as my wife uses the car daily booking in is a PITA. You get £10 off for returning the bottle.

Lesson learned though, next time it will have to go in for the day. The other PITA is the low pressure connection is behind the wheel arch liner, the so called pro's I've spoken to say there is no need to use both connections (in other words, can't be arsed to take liner off), why does the machine have two hoses then?!!

Well, it's stop doing it now, maybe lack of use? Next time it will be done properly though! I'll remove the arch liner for them
