hi lads

i just had my air con serviced at a local toyota dealership and to be honest i dont see any difference in what it is like now and before , there dosent seem to be any detectable difference in the air exiting the vents whether the ac is on or off. the cars a 2004 2.0 d4d with the electronic climate control

i suppose the main questions i have are

1 how long should it take to get cold

2 what temp should i expect from a system that is working well

3 what are the correct settings i should be using

4 should i notice anything like a higher rev on the engine when its switched on

any help or advice appreciated before i bring it back to them

I have a 2004 TSpirit and the air does get cold pretty quickly - I usually have it around the 19c / 20c mark - if the weather is warm outside you'll certainly notice it. One thing is make sure the AC button is lit and that it's set to Auto. When it's really warm outside (around 24c+) you'll notice a very high blowing when you first get going (i.e. are in motion not when you're sat there stationary) and then very, very cool air.

I didn't notice a higher rev on the car though.

Personally I'd say settings should be AC on / Auto / whatever temp you like - say 19 if it's really warm out there.

Mine is a 2006 before the facelift, 2.0 D4D and it has the "Automatic Air Con". When turned to Auto it will start slowlly and not very cold then the fan starts increasing the speed till "normally" the maximum speed. If I'm driving in city, with accelerations and braking, the temp will not be very low, however when I stop at a traffic light the air get's cooler. At the hightway, at full accelaration we get good cold from it. The Air Con Engine is "tyed up" to the main engine. If the engine needs power to accelarate, somehow the Air con will loose cooling power. When you switch off the AC you'll notice a kind of "relieve" from the engine - it's recovering some RPM's used to power up the AC.

By the way, on my two Auto AC equiped Toyota cars I had (the 2002 Corolla 1.4VVTi and this Avensis) I never had to "refill" the AC system nor I had any other problem with it and I shurelly use it very often. Both cars were/are with me for 4 years. I know the actual Corolla owner and, after 8 years still working fine. I don't understand why the other brands have to "refill" the AC either every 2 years or more than that...

my 2.2 t spirit avensis speeds up by 200rpm when the ac is turned on while the car is idling

i recently had the ac regassed on the car....prior to the regas the engine never revved up because the ac sensors the gas... no gas no compressor

Hi, when you had your car re-gassed the garage should have checked the car before you had it back, it should start to put cold air out within a couple of minutes of switching the air con on, if it don't then something is wrong.

There could be one of about 3 things that go wrong, first no gas in system caused by leak, the garage should have pressure tested the system to check for this, second thing no power to air compressor, could be a blown fuse, third thing and some thing you don't want, a failed air compressor.

If you set the climate control to low the temp from the vents should be around 5-8 centigrade and the engine should increase by 100-200 revs, if you are not getting this then you have a problem.

If by very bad fortune you have a dodgy air con compressor don't ask Mr Toyota for a price unless you are sat down.

surely if it was the compressor i would be hearing loud noises from it ( as posted in earlier topics )

thanks for taking the time to reply

not necessarily ... the compressor may be dead

but they wont work if there is insufficient gas in the system

hello mate

1. It depends on what is the themp inside and out side + adjusting value;

2. the lowest themperature for setting is +16 C ;

3. the correct settings meaning depends on your favorite themp inside;

4. in case no leaks have been disclosed belong to the system - it means the A/C performance must be sufficient even at idle rpm.

You'd must to know that if you sellect an air circulating mode -- this helps to reach desired themp more fastly thanks to a closed internal cabin circle; but if you select suction from outside --- this will reduce the time to reach desired set themp because of outside hot air. Moreover in order to evaluate good performance of yr A/C system you must be assured that the fore gas radiator (heat exchanger) is free of either dirt/insects on its ribs + outside air themp sensor is also clean giving no false them signal to the ECU. Besides the unit responsible for gas boiling is called thermoexpansing valve or throttle valve that gets a signal from both external air them sensoor and from cabin sersor covered by plastic strainer (be refered on the dashboard cclose to ignition key socket). Besides your pollen filter must also be cleaned or changed. In case they have regased system as per manual or even by tip sticked under the bonet - the system must to work. If you still experience bad performance -- get to the dielership and insist to investigate it for free basing on the warranty. Good luck/Igor

Hang on a mo ! Am I missing something here? Didn't he just say

"i just had my air con serviced at a local toyota dealership " ?? and here you are talking about what might be wrong with it? Take it back to the dealer, explain that you don't think it's working right and get them to have a look while you are there. An Air con service finishes when the system has been run and checked for performance, if it's not performing properly, they haven't done their job.

My air con seems to blow cold within a VERY short distance. Always left on auto and for extra coldness press the recirculate button...........now thats cold :-)

Hi all,

Personally, I don't understand why you guys go to Mr T to get A/C serviced. They tell me every time I have car serviced, that the a/c needs servicing in which I tell them Quick Fit does a more thorough job and a lot cheaper....Yes but.....but nothing your just ripping people off!!!

Oh and by the way, all major dealers recommend to have setting at 21c AUTO with air circulation activated. I've allways leave this setting and it's very comfortable. Give it a try on the next heatwave.

well it turns out the compressor is gone and there is one pipe leaking ..1000 e to replace .when i pressed them on the issue of why this was not detected ofter the service i.e. was it not checked to confirm it was working correctly they didnt really have any answer , the service manager as good as fobbed me off with some rubbish about todays readings then legged it out of sight , i must admit the lady at reception spent more time with me than him ,

the question has now been raised in my mind as to the quality of the work they carry out on my car and others .

Dealers that treat customers like that do not deserve to prosper.

Vote with your feet (or wheels) and go to another dealer.

Aircon servicing/regassing may only be performed by authorized aircon service stations.

At least, over here.

In fact it's illegal to re-gas and release a car's aircon back to service when the automated service unit detected a leak in the system.

It is mandatory for an authorized service station to use an approved and regularly tested computerized machine, which will not even complete the service cycle (that is, re-gas the aircon) when it detects a leak.

There's nothing mysterious about todays readings when its display reports:

"Aborted, System Leaking".

So, it's useless to fill a leaking system in the first place, it's illegal, fraudulous if they charge you for it, and they risk losing their license as a service station if you push this forward.

I would complain in writing (c.c. Toyota), ask my money back and avoid them in future.

Echoing what Thermal said, you want, at the very least, your money back for the air-con service that they didn't do to the neccesary standard.

P.S. charging you for something they haven't done is nothing short of Fraud !

If you go to an Air Con Specialist, they will re-gas it and add an chemical dye to the gas. They then request that you return when it stops working again and when you do, they scan the engine bay with a UV torch which shows up the location of the dye and thus the leak.

They do this for a very low price, although I cannot remember it and it should be sorted in no time. It is highly unlikely that the compressor has gone...

go to kwik fit

they promise you if the a/c doesn't work no charge

just go there and act daft and don't say anything about trying to have it done by Mr T

Hardly a specialist.... the only thing I trust them to do is remove wheels and even them it takes some consideration.

Get to an A/C specialist and pay a small charge to have it done properly by someone who knows what he is doing, instead of reading it out of a book they can barely read themselves.

But haven't you heard? "You can't get better than a Kwik-Fit fitter" :bash: ROFL!

I went to a AC specialist; he first topped up the system and never noticed it had a leak (Lots of AC oil around), I dried the oil took it back and he could not see the leak with his UV light, I found the leak with a mirror underneath, he fitted a new pipe and charged me again €100 for the top + fiting €405
