Let us know how you get on mate - sometimes and only sometimes my MK4 fill ok from the cylinder but when I open the valvle to let the pressure out to disconnect it the MK4 starts blowing out the air Ive just filled it with but its just now and again it happens. There is no leak from the MK4 when filled though just at the disconnection.

Interested in what they say to you.
