V50 Air con
Hi, i have a V50 Drive and noticed that the air con is not working. I have had a mate check the gas level and he said there is "some" present but not too much. Question is does the compressor stop working if there is not enough gas? I don't really want to get it re-gased and still find it does'nt work. Thank you in advance for any theories.

With low gas, the compressor clutch will normally engage for a few seconds then disengage so you first need to look at whether the compressor clutch is even engaging.
If it's not engaging at all, the problem could be something else.

Probably the condenser, it’s a known fail on V50’s

5 weeks ago (during the last warm spell we had in May), my vents were only blowing warm air (car was new to me, so this is the first time I noticed the issue). I happened to be near a Halfords, so thought I'd try the regass for €35. The guy rightly pointed out that if I had a leak or mechanical issue, it wouldn't do anything, but I said to give it a go. When he put the gauge on, it read low pressure but not empty, so he said there was a chance it would work, so I gave him the go-ahead and away he pumped. The air coming out of the vents started to immediately cool.
5 weeks on, and here's the temperature at the vents yesterday when it was 32° outside (I calibrated the thermometer before taking the reading). In my case it worked a treat so far anyway. |

It is... A bit difficult for me to believe..
Unless one of points below is met: You're NOT in Europe (or have car imported and not checked on import) Or Thermometer is bad. To the best of my knowledge no car in Europe is permitted to blow conditioned air even a small bit below 16 degrees Celsius. Legal matters. (I think I know where it came from, but its not that relevant- boneheads, in short) Which is it?

Firs time I heard about it when refilling my aircon, last year.
Tech was teaching his subordinate (hilarious) "how and why AC works" His story was about "boneheads" abusing AC, setting temperatures too low, catching colds etc and complaining/seeking reimbursement to/from manufacturers. Yet, today I tried to find some more info, and it proves as tricky task. Here's one of better ones: Quote:

You may well be right on this one, yet I've never seen any car that would allow temp setting below 16.
And there's good point re- evaporator freezing/ice cover. Essentially, by thumbs logic, to blow air at ~5-6 deg, coils would have to be in the "minus" temperature range, as the air passing trough cooling element will never achieve temperature as low as that element, and also other way around (easier to check- use home radiator) air passing trough heating element will never achieve temperature as high as that element. I may have difficulty confirming it with actual numbers of paragraphs or whatever it is called, but I can see logic behind it. Thus, I do believe there is such law.
