I think it works as follows:

Blank: Normal Aircon
Auto: Climate Control
Econ: Same as a normal heater without Aircon
Both: Adjusts the temperature to the set level but without using the aircon

Is this right?

So with nothing displayed other than the temperatures the aircon could/will be on?

Makes sense to me...

But then i only just realised that holding down the next track button on the steering wheel moves you to the next folder of MP3's....

I don't fully understand my climatic system. I seem to be able to have auto by itself displayed, econ and auto displayed, just econ displayed and no econ or auto displayed. I can't work out what the difference is between them all.

I thought econ was to supposed to automatically change the fan speed but without the aircon on? If so what is the difference between just econ displayed and econ and auto displayed together?

AUTO maintains the temperature and the blower speed will drop once the temp's reached. ECON switches off the air con compressor which reduces the load on the engine hence the improved economy. (but the lowest air temp you'll get is what's outside the car... no chilled air) Compressors are nearly all variable displacement now and the load is negligible unless serious cooling is required. Gone are the days when you could hear the relay click and the revs drop when the A/C button was pressed:funk: Btw. When you unlock a Pheaton on a hot day the blowers reverse and draw all the hot air out of the system so you get cold air much quicker. It's alright for some...

Yes but the revs actually rise on the 2.0T

CV7 has it right...

Blank = manual fan control, a/c will come on as required but fan speed will not alter. Enable this mode by setting the fan speed manually from the "Auto" setting (without "Econ" displayed)
Econ + Auto = no a/c, fan speed is controlled automatically
Econ = no a/c, fan is in manual mode
Auto = as per CV7's post

The system also cycles the a/c compressor at a low (~10%) output to prevent problems with the seals, etc. i.e. you don't have to switch it on for half an hour every fortnight like you used to with older a/c systems.

my steering wheel has a seperate button for changinf folders.

anyway,

when i had my audi, econ on and it was cool, econ off and it was time to put a extra coat on as that **** was cold.

but yeah my leons aircon isnt quite as good, but i do the rolling with the windows down trick to get the cabin a bit lower.

and the ultimate cool would be a phaeton on airride, and bentley mulliners but thats off topic

So even if you have econ on all the time the seals will be ok?

quick update: Mine was faulty in the end. It required a new high pressure sensor fitting - done under warranty. Nice and frosty now :)

I have a good tip for saving money on Air Con....

When the missus gets in the car on a hot day, simply ask her if she has put on a bit of weight recently....

Firstly the harsh intake of breath will remove all the nasty hot air, and secondly the ride home will be plenty frosty enough without ANY kind of cooling....

Thats my top tip anyway!

been loads of air con probs caused by faulty pressure switches in all VAG group cars over the last few months, many dealers have zero stock of the switch and I think they are on back order till the midle of the month, how do I know coz mine broke, the stealer coudn't diagnose so I used my 20 years of mechanical knowledge to diagnose the fault, check logged ecu faults etc check to see how much gas in air con system (non at all ) something a main dealer should be able to do and hey presto faulty air con pressure switch.Phone the dealers, tell them what to order, ok will get one....oh hang on its gone back order.Warranty whats that?
