I use Halfords eze gas to recharge at the start of summer .They do a leak gunk as well which used a few yrs ago once .
Judging by the gauge on the recharge bottle ( about £60 ) the system was approx 1/2 full .
A bottle lasts 3 fill ups .The instructions that come with it are self explanatory .
We were ice cold at the WE outside temp was 24 Sat afternoon York’s area .

Sure the R 134 partially leaks out by the autumn but the time / hassle of chasing it in my view at present not worth it .My AC pipes front to rear looked new when I acquired the car back in 2018 so I assume r134 compatibility?

On larger euro trips ( outside temp 30 + degrees ) and blazing Med sun we place a yellow cotton cover over the black dash top .
Holes cut for the 3 vents .This these cars don’t have tinted glass and the solar glaring / glazing effect is prominent.
Covering the “ black “ helps .

The only problem ( well documented on here ) for GT 4 owners and I suspect 308 owners as the identical mechanical systems…is after a couple of hrs the air box over the passengers feet starts to drip condensation as it gets so cold and humidity causes the water to condense .So my wife places a small towel over her shoes …..when that starts to happen .

Like the filter mesh in the post above , when new there was a black spongy mesh lining the heat exchanger ( the box above the passenger feet) and a drain .Check the drains patent obviously.But without the sponge lining the exterior of the box gets so cold thsts where the water condensers and ends up dripping .This is additional to the internal condensation that runs out with the drain .Your “ dust and crud “ could be this lining breaking down throwing black particles into the cabin ??
Eventually it’s all blown out leaving an un insulated box and resulting in the wet feet syndrome.

To fix its a PITA job to remove and split this box , re glue another insulated lining inside .Reassemble and re gas the whole thing up .

As we have albeit a functional AC with a easy workaround the 3#8 “wife wet feet syndrome “ I have left this job .
