I think my climtate control unit is starting to fail!!!!! - Have noticed that 'cold' setting has gradually grown less and less cold, indeed, yesterday in the auto setting on full belt, there was no cold air only boosted fresh air. I am wondering if it requires 're-gassing' and just exactly what is this procedure, will it have any knock on to the rest of the system? The 'Book' icon is not displaying so hope blend motors are ok.

BoB-B uttered summat worrerz funny about:
A google of the group will throw up loads of threads since June (when the sun came out).
In a nut shell it sounds like you need a regas , costs around £50 on your driveway, make sure you get a quote first. Should not affect the rest of the system only takes around 30 minutes to do. It's like blowing up a tyre except it's refrigerant being pumped in rather than air. Good installers will vac the old stuff out, check it will hold a vaccume (no leaks), then refill

And really good installers will replace the receiver dryer, add oil and then re-gas it.
Or do it yerself. Check under the bonnet on the plate that it's R134A refrigerant then buy the kit from ebay. You need a tin of gas and a connecting tube. Takes 10 mins. TonyB
Suggest, particularly, you get it checked-out for leaks or you'll be having an expensive refill without curing the problem. Just had mine done and there was a leak in the system which had caused the symptoms you've described (I'm told that it's rare for gas to "just leak out for no reason"). The specialist found the leak by injecting a dye into the system and then letting it run to see where the dye leaked out. Just to add to the earlier excellent advice (above) - good installers will also check the weight of refrigerant they are putting in, as all systems require different amounts of gas and these are specified by the manufacturers
Beware of the cowboys who'll pump in a bit of gas in 5 mins, charge you £50 and then have you wondering why you're back to square one in a fortnight.
[As an aside, I've heard that there is now on the market a sealant (c.f. radweld) which will cure small leaks in aircon systems but I've not found it offered for sale anywhere.]Let us know how you get on.
