Hello everyone, long time lurker here, always found this the place to go for info.
Long story short(ish), my trusty 2009 Fabia Mark 2 (81000 miles) needed the AC regassing at the end of 2022 - got it done on a Groupon coupon at ATS - this only lasted a few months (and is the first time I've ever had the system regassed since buying the car new in July 2009) - realised I must have a leak somewhere but ended up getting Halfords out for a quick £60 refill job to see me through the "summer" (at the beginning of June).
This lasted around a month so I left it for a bit, just not having the time to get round to it again, plus the weather wasn't so great here in Scotland that I needed it. However, as the temps have rose again and with the winter coming in and the thought of fogged up windows while the five of us pile in for the school run I thought I'd give another quick refill a go myself to see me through to service and MOT time in November.
It seems I may have discovered the problem - when I started to add the topup gas I could hear some hissing coming from the high side port and when I unscrewed it the gas was coming out. I've tried to tap it slightly to clear it in case there was dirt in the connection but to no avail.
It does seem like the black seal is missing that used to be there (see pics - it's still there on the low port and nothing comes out of there).
Now I'm an IT repair guy to trade and I don't know much about cars but I'm happy to get my hands *slightly* dirty.
Anything I can do to fix this myself? I was looking online for ages and they all go on about Schrarder Core Valves and replacement but is that the valve here? Or is it a ball valve? Can I just get some o-ring type thing and stick it in there to make the seal again?
I should say that I run the AC continually - winter or summer, it's always on, I like the fresh breeze on my face...
I'm sure I'm missing something simple here, hope you guys can help me out.
Cheers in advance.
