Well I have now managed to get the AC fixed on my car and has all been done under warrenty.

The reoprt from the dealers diagnosed the fault as.

System low on pressure, leak checked and no leaks found, system re-gassed.

When operating AC, radiator fans did not come on, and system pressure raised (I think it said to 26psi)

Investigation into the fans not working revealed the AC controler and engine ECU were not communicating, and it was found that some coding in the system was incorrect, this was corrected and system opperated as it should.

The AC is now working and gets nicely cold, but my concern is still why the system had lost its gas within 18 months when no leaks were found?

Could it be that if the fans were not working, when the AC was turned on and the system pressure was raising too high, then there is a pressure relief valve to release the pressure resulting in a loss of gas in the system?

Also if the coding on the system was found to be incorrect, then I think it is highly likely that the AC has never worked correctly from new as these things dont change themselfs.

I am pleased to have had the problem resolved and pleased by the service provided by Rainworth Skoda, but dissapointed at the lack of willingness to investigate the problem by Hortons Skoda who I drive past every day, and wanted me to agree to a charge of £70 to investigate the problem, even though the car is still covered by manufactures warrenty. Needless to say Hortons will not be getting the job of servicing the car in the future!

I think Skoda UK need to sort out some consistency between their dealer network for investigating faults on cars still covered by warrently.

To keep good customer service and happy customers then their priority should be to find the problem first with no talk of costs, and then carry out the discussions about if the problem is covered under warrenty.

Wouldn't be 26psi, more likely 260psi.

There is no PRV in the system, so either you had a tiny leak or the system wasn't fully gassed at the factory (more than likely).

I have no idea what sort of pressure the system should operate at, but thinking about it, 26psi does sound a bit low.

My real concern is I havnt really been given a reason why the system was low on gas, and I was trying to find out if the fact the radiator fans wernt operating could have contributed to the lack of pressure/gas.

What I dont want to happen is to be told there are no leaks and the system re gassed, and then a year down the line loose the gas again and find out just out of warrenty that there is a leak in the system.

Just re read the mechanivs report, and it was 26 Bar ie 380psi

That's more like it.

It COULD be a leak - some are hard to find if they are only small (e.g. in evap unit behind dashboard). Normally they will vac it down and see if it holds vacuum for a while. I take it they added UV dye to the refill?

I used to work in motor trade and many cars came from the factory with less than full charge - especially Vauxhalls. Indeed it was unusual to find a Vx that had its full fill!

I aggre EGC , common practice for manifacturas to short fill ,saves money!!!!

Well fingers crossed, my problem was as a result of a short fill and not a leak somewhere undetectable.

Or if it is a leak, I hopr its very small cus I dont want to be having to have the system re gassed every year.
