Had the air con re gassed today and was expecting to pay just over £70 but the cost was just over £43, a good result. When I said about that I thought it would be over £ 70 I was told that the air con gas has gone down in price. So if you need yours doing it might be the time to do it.

Thanks for the heads up, drove the old girl on Sat and the air con was so, so. :(

The MOT is due soon so will get them both done at my Indie :rolleyes:

R134a isn't exactly expensive and never has been. It's under £10 a kg. Most cars only hold about 600g.

CLK320
I left my CLK320 at my local garage this A.M. for A/C service. They did the job but say a bigger problem, still does not blow cold. They think it is a bad wire (16 yr. old car) or a "control unit". They don't want to charge me labor for searching for the problem and recommend taking it to an auto electrician. If it is the "control unit" ? it will be big money.
Does anyone have any ideas on this before I start a wild goose chase??
Sorry if I seem to have hijacked this thread.

Most of these garages use an auto machine for A/C re-gassing. Seriously, it's not doing a proper job of it!
You should really change the receiver/dryer before doing a re-gas. As this collects all (most) of the moisture from the system. A bit like those silicon sachets in with your electrical goods!
A cheap way is to at least remove it and empty it out.

I like to leave a system on a vacuum for at least an hour, that's after a positive high pressure charge of OFN to check for leaks. An hours vacuum will boil off any moisture in the system. None of the "auto" machines will do this.

Take it to an air-con specialist it's value for money in the long run.

I pay about £150 for a 13kg cylinder of gas, then there's PAG oil, the correct grade, not some generic pish and also some UV dye, plus the cost of the nitrogen purge.

As an example, my ML420 just took a fraction short of a 1,000g recharge to get an acceptable reading off the gages. Spec is 946g if I remember.
