Seat exeo temperature

[Northstander]

With econ light off your aircon is on which will power the radiator cooling fans so your engine will run cooler and take longer to heat up.

I think I have had the air con on since I got the car!!!!

Econ is short for economy, if econ is off then FTE mode is active, air is drawn in from outside cooled by running the aircon (to de-humidify the air) then heated (by the electric duct heaters if the engine cooling fluid is not hot enough).
If econ is on then the air is just heated by the engine cooling fluid (no load on the aircon compressor, no extra load on the alternator to heat the air, hence economy) if the engine is not being driven hard than the cooling fluid will not be very hot, hence luke warm air.
This is my understanding of the situation, I may be totally wrong.

Your right on some points but ,
They dont have electric duct heaters of any kind all the air con button does is shuts the air con compressor down
Luke warm air is caused by the engine obviously not being up too temperature or if the cars up to temp its the climate control doing its job as you only get heat until the set temperature is reached , like wise it works the other way when the temp is set too 16 for example the ducts will blow cold until that temp is reached then the ac etc will shut itself off only to resume when the temperature inside the car alters
The only exception too this rule is when the climate control is set either too Lo or Hi were it will blow cold or hot air continuously no matter what the internal car temp as theres no specific temp dialled in .

On another note some diesels including VAG vehicles have pre heaters installed these are diesel fired and heat the cooling system water quicker under cold conditions
Not all vehicles have them thou as there an option part .

I am getting a far better mpg now I have the econ button on. Was normally getting 42 now up to 50 mpg.

Turn if off for a while every now and then or the gas will escape and you will have no aircon when you do need it.

I don't mean too be one of those people but who the hell told you that the gas will escape if not used

Don't get me wrong it should be used but it's certainly not going too dump out gas because you don't

I thought if it isn't used then the seals on the pipes etc dry up and the gas can seep past the dry seals, I have mine on auto all the time I find it makes for a much nicer journey no foggy windows and a nice regulated cabin temp

 

[Paul20v]

The compressor shaft seal will leak if the shaft is not rotated every week or so, very surprised you don't know that

Rubbish the seal is on a shaft , rotating it or not wont make it leak unless its not used for that long it rusts
But if that happens you will have other problems on the car of more concern than your ac

as already said i agree it needs using but thats not the reason
Its more important too get it properly serviced every 2yrs as so many people dont
And a dont mean just a gas top up

Reporting back from my Exeo thermostat change yesterday....

Took the car in to Arnold Clarke and explained what had been going on. The general opinion between the parts manager and their in-house VAG trained mechanic was that a thermostat, housing and coolant change was the way to go.

When I got the call to collect the car it was fresh out of the service bay and pretty much up to temp already. It was also 8 deg outside. Within 2 miles the water temp was reading just below 90 deg and stayed like that for the 5 miles home.

Starting from cold this morning (4 deg above frezing outside), back on the daily 15 mile commute, the temp got to 70 deg just before arriving. So I'm "presuming" at this stage that the temp would increase further given a longer run. With that said, it's already an improvement on recent temps and I've got some peace of mind.

They also plugged it in carried out a full scan for sensor errors etc. Nothing showed, past or present.

The car was fully valeted and given a clean bill of health including an emailed video walk around by the mechanic who carried out the work.

£132 all in due to a totally legit "friends and family" deal from my cousin the parts manager. I believe that's a 50% discount. :hug:

You are correct on some points but check page 159 of the Exeo Owners Manual re the auxillary heating, it is fitted on Diesel versions (as most Exeos are) and turns off in Econ mode to save fuel.
I am fed up with these keyboard warriors

Owners manual when written is for All european countries I have one exeo and 3 B7 A4s in my possesion right now all diesels and non of them are fitted with aux diesel heaters , which by the way when very rarely fitted are under the bonnet and not in the air ducts...
Answer me this ,
How many cars in the VAG group do you work on ??
How many cars in general do you work on ??

And your fed up with keyboard warriors , Try getting your hands dirty and work on some cars you might get some experiance in the real world as far as vehicles are concerned instead arguing and by quoting **** you have read somewhere .

Now who is talking rubbish?

Good info from here http://www.google.co.uk/patents/US3738118

Means for lubricating vehicle air conditioning compressor shaft seals
US 3738118 A
Abstract
A vehicle air conditioning control system including means for lubricating seals such as compressor shaft seals during prolonged cold weather vehicle use when air conditioning is not required. A momentarily closed relay, responsive to use of the vehicle, is connected in the air conditioning electrical control circuitry in a current path independent of the normal air conditioning energizing circuit. This momentarily closed relay energizes the air conditioning compressor during each use of the vehicle for time period sufficient for proper lubrication of compressor shaft seals but sufficiently short to prevent cooling during cold weather. Lubrication of the seals during each use maintains a thin film of lubricant between rotating and non-rotating faces of the seal preventing frictional heating of the seal faces and consequent damage that would prevent the faces from supporting the necessary sealing lubricant film.


What is the reason in your mind then?

Nice quote from google and by the way (thats sarcasm) ,
you will be quoting wikipedia next


Cold weather it says and for long periods of time ,
1. this country doesnt know what cold weather is .
2. whats a long period of time in relation to the cold weather ?


The oil doesnt just dissapear off the seals in a short period of time its suspended in the gas
using the air con does as ive already said need doing but too quote something you have read with out any experiance in the field is just incompetent .

And also just too clear up , the AC systems should be serviced every 2 yrs
this is so the gas gets changed and while this proccess is being done it goes through a drier system in the machine to remove the condensation out of the system which causes problems obviously , when the gas is refilled a percentage of oil is put back in with the gas this is the lubricant used to oil the system ,
again this should be done every 2 yrs as part of one of your services not doing this will cause more problems than not switching your AC on for a couple of weeks .

If your not willing too listen carry on with google as im sure whoever wrote it will be happy too help you fix your car because obviously they know better than someone working in the field in the real world

Ive said my piece so you can argue with yourself now
Im out .

Hello,

My seat exeo 2.0 tdi cr CAGA has always taken ages to warm, but now it really looks like something is off. Fuel consumption has also increased in my opinion, so i ordered new thermostat. I tried to look for guides how to do it, but cant seem to find any :s. Do i need anything else than the new thermostat + coolant? Thanks alot
