Hi all, 

Does anyone know the aircon type for a Skoda Fabia 1.4 tdi, MK3, 2015? Tried checking the owners manual and under the hood but cannot find anything say if its the older or newer type gas. 

 

Thanks, 

Martin.

Groupon was or had a recharge deal with ATS for under £40.

LOL, you have read my mind. That's why I was asking - booked mine for this Saturday

My wife's 2015 was done this afternoon, person in front of me in the queue when I handed it in was also in with a Groupon voucher as was the  in front of me when I collected it!

 

It sounded like that that branch gets a lot of work from the local airport car rental companies - sorting out front wheel alignments!

 

I really must try harder while there is enough gas in the system, to find where the leak site is, this is its 3rd annual regas!

Do you run the AC all year round?

 

When at work we used to get cars in regularly as the weather warmed up, the mechanics would tell me the rubbers tend to "dry" up a little as they need the oil that circulates in the gas to stop them shrinking.

It might be leaking so slowly over time that it's hardly detectable with UV (if dye exists) or leaking where you often don't check.

 

Just my 2 cents, might be worthless information.

The plan and design of the AC compressors in all these newer cars, and back to at 2002 in the case Polo and so Fabia, Ibiza and A2, is to have a variable displacement compressor and so they are driven constantly and their capacity is varied depending on the system demand - but they have a minimum capacity of roughly 5% this is built into the design so that a small amount of refrigerant and oil is always circulating round the system - to minimise leakage across all "rubber" ie porous areas.

The other reason for changing from "clutched" fixed displacement compressors to variable displacement compressors is improve efficiency/emissions so the compressor output matches system demand.

My older 2011 Audi S4 get next to no running throughout the year and it also has a variable displacement AC compressor, again its AC is only used when required and it has only ever been "topped up" by me 5 years ago, though I do plan to check its cooling performance this year and add in some more R134A as it must have lost some over the latest 5 years. I've never planned to top it up back to the original running pressures, only to improve the pressures over what they are when checked.

 

This needing topped up every year has only developed over the past 3.5 years so I think that there is a crack or damage somewhere in the system, it would be handy if it was in the condenser, though so far I've not been able to detect any leakage anywhere are the under bonnet area.

@rum4mo Hopefully it's not leaking from evaporator inside the car, bit harder to see.

 

I'll ignore that suggestion, or just carry on with recharging it, that would be a horrible job and I do know that it is a possibility!

Yeah not one I'd like to tackle if it was.

An experience maybe.
