Qbee I see back in your first post you mention you fixed the A/C on your car. Can I ask what symptoms you had apart from the obvious, and how you fixed them. Mine has a leak but garage haven't been able to source where from. System has been run for an hr without gas levels dropping.

Thanks

Errr....I bought my car from a lying Yorkshiremen (other liars are available).
He knew why the aircon didn't work, but said "yes mate, it's working fine, probably just needs a re-gas". Regas didn't solve it.
Took it to an expert, who pointed out that the compressor was siezed and a shorter auxiliary belt had been fitted to bypass it completely.
Bought a recon compressor off Ebay and a longer belt, fitted, regassed, worked ever since.

So that doesn't help you.

Presumably the operative who regassed checked that the compressor is actually working? It's down the front left corner as you stand in front of the car, and can be heard clicking on and off as the car idles with the aircon switched on and at 16 degrees.The revs fluctuate at the same time, if that helps.

To depress you a bit more, I owned an Audi A8 for three years and never managed to find the reason why the aircon didn't work. In the end it had to be a pipe leak somewhere deep in the bowels of the engine bay or dash. If you've ever seen the engine bay of an A8 you will know why we couldn't find it.

The aircon on my wife's Saab 9-5 gets re-gassed every year, no visible leaks, works for about 6 months and then seems to lose all its gas. All I can say is "good luck".

Cheers for reply, the system had been working fine. I then got it regassed at kiwi fiit in April,all was well but about 2 weeks later it was blowing warm. Took it to my local garage who seemed confident the system was holding pressure and there was no leaks. 10 days later it was blowing warm, I am now wondering if kwik fit moved or damaged a pipe causing a slow leak. I doubt I will spend time or money on it.

I did have an issue on my wife's Saab's aircon - it was traced to a pipe down at the bottom front of the engine bay, and found by putting a flourescent dye into the gas and seeing where it stained.
