406 hdi air con gas leaked

[patrickgledhill]

Hi guys, the gas in my air con system leaked out over the last week. So I thought before I go taking to the workshop and handing them hundreds.. I'd ask if there were a common place for it to leak.
Any knowledge is appreciated
Cheers

Mobile AirCon guys are generally good and cheap. It pays them to be in and out ASAP

I don't think there's a common place as such apart from any connector as they have seals in.

Best to have it checked for leaks (they tend to put UV dye in anyway now I think)

Look for a corroded condenser, also pinched O-rings at common service points (drier, TX valve). Putting the rings in without lube is problematic. A UV torch is cheap and may help find leaks.

Condensers fail in the centre, where the fan shot blat it with grit. Otherwise they are pretty reliable

cheers Guys for the info. Does the system need to have dye put in for the uv light to work?

Look in the sight glass if you have one on the drier. Fluorescent green-yellow means there's dye in it. Clear to brownish tint is undyed.

hmm not sure if i do have a sight glass with check it out, from memory when i found the drier is was very small and up by the condensor

Took it in, they had a pretty good idea that it leaked from the compressor. they went ahead and replaced the hose o rings and changed the filter...this was full of gunk.. and they put dye in the system. all for $500 seems to have fixed it but time will tell!

Cheers guys
