Hi Air con wasnt working so took to Mr Clutch for a regas and leak test. Apparently they checked for leaks only in the engine bay (and found none) and not inside the car.

Anyways it worked for a couple of days then stopped working. I havnt a clue what air con parts are inside the vehicle that could leak. Any Air Con engineers local to Bromley on here??

Correct leak testing and a/c servicing are as good as the operator checking the system. Sounds like they never checked for leaks as that procedure needs to be done over a few days with a special dye in the system. Then is checked again after a few days with a black light. Go to a good dealer who has the a/c kit or go to an a/c specialist.

Evaporator or pipework to it but its unlikely.
As David said get it checked out by somebody with a UV light if its only lasting a couple of days the leak would show up.
My money would be on the condenser.
I have a very small leak on my 307 system somewhere it lasts about 3 weeks and I cant find it have even checked it at night with UV but I suspect its the condenser again :rolleyes: but until you remove the bumper, fan and debris from it you cant see much of it.

Air con regas

Hi Leaks should be traced using a dye injected into the system traced with a U.V. light and a Electronic Leak detector, most garage based A/C technicians
DO NOT have the amount of training to carry out a Full leak test. Contact a local Refrigeration Engineer and they will pressure test using Nitrogen and if they cannot repair the leak then they can use a A/C leak Sealer ( not to be confused with a Rad sealer to stop water leaks). I repaired my own car 3 years ago with a leak sealer and cabin temperature is a very cold 4 degrees C. Also change your Cabin Pollen filter, but go back to Mr Clutch and demand your money back as they have not carried out a full leak test and have regassed a system without carrying out a Full pressure leak test and that is a criminal offence report to Local council. ( 45 years A/C Refrigeration engineer)

The only way you can legally check for air con leaks is with Nitrogen (OFN). Using Dye is no longer permissible. If your air con engineer knows the system has a leak they can no longer add refrigerant a requirement when adding dye (if the system has no refrigerant).

If an air con system is fully sealed (no leaks) your air con technician may add some dye to the system which will aid diagnoses should a leak occur in the future,this is often done during air con service.

Air con Tech's who evacuate/replenish refrigerant (R134a) on cars/light vans etc (mobile air con - MAC) have to be licensed. This came in to effect 4th July 2010.

I don't know if its any help but I have the same problem, had it gassed up and checked for leaks (at an aircon specialist), compressor clutch would still not engage (no power to it), he had it on the computer and found the fault to be 'condensor sensor' He's ordered one from dealer £56 +Vat, waiting for it fitting. Will cost me £200 in the end including diagnosis. Just bought the car too! Never checked the aircon when I handed over the notes - stupid me. Pug 407 1.6HDi.

Sods law Wayne! You ain't the only one who doesn't check A/con operation. Only if we bought cars in the hot weather it may spur buyers on to check operation.

Hope your sorted when the parts fitted.
All the best

Thanks for the kind words Terry, I did get the car at a bargain price for the mileage/ condition (well it is very shiny) FSH, one lady owner etc. Trader told me it may need 'gassing up' and I bought it on that condition. Also found out some time later when stuck in traffic that the cooler fan was burnt out! £300. So £500 quid spent already and knowing my luck I'll be getting the old heater flap problem too - no such thing as a bargain is there? Its is very nice and shiny though lol. I expect to be posting a lot on here.

Take Care
