Hi

I have a 1.9 elegance which i assume has climate control as you can adjust each side to a different temperature.A couple of weeks ago it wasn't getting cold.The blower is still working although you can hear a sort of noise that sounds like something is rubbing or a leaking gas noise.Not noisy but you can definitely hear something.I turned up the temperature yesterday and although the Digital readout  showed HI the temperature of the blower didn,t rise either.I'm worried.Can anyone help?

Thanks 

 

Just a few points for clarification:

You will only get hot air on HI if the engine temp is up to 90C on the display. Was your engine hot when you were checking?

Noises from the blower are often an indication of crud getting into the blower from the air intake. When was the cabin pollen filter last changed?

Is the air conditioning also not working? If so, then you may have a failed air flap as this will also make noises from its motor if its gear has stripped - known problem.

 

Finally, if possible get a scan made and report the error codes.

 

 

Strange noises are sometimes an indication of low gas pressure/leak in A/C, usually a due to corroded high pressure sensor/holed condenser.

 

It may be worth asking the likes of Kwik-Fit to check pressure/refill.  They are cheap and offer a free A/C performance test.

Hi 

I'm pretty sure the engine was hot but will give it a good run tomorrow and check again.looking at the service history it could have been 20.000 miles since pollen filter was changed so 'll order one.I assume its not to hard a job to change? I didn't know it had air con too just climate control.What is the difference and what control / Button / dial is the air con? Is the failed air flap an expensive job ? I'll try and get a scan made and see what coames up.

Thanks for the information

Thanks for the info i'll check local if local garages can do a check. corroded high pressure sensor/holed condenser both sound expensive!!! sad face

You mentioned you have climate control. Climate control also controls humidity, even on hot damp days and rainy days when you would otherwise have "steamed up" windows.

It does this by cooling the incoming air via the air conditioning. High water vapour is condensed out and the water drained away. The cooled air is then mixed with hot air to reach the temperature you set on the controls. 

The advantage of climate control is that you can set your required temperature and the air will always be at a comfortable humidity and temperature. This is a simplified description as it also monitors the sunlight level in the car as well as temperature sensors at different levels.

 

The normal way of switching on climate control is to press the AUTO button. There is also a button to switch off the air-con bat pressing AUTO will switch it on

As your is the Elegance trim, I would expect it to have these features. 

 

 

The pollen/input air filter is mounted below the glove box. Undo the two finger screws, slide the filter to the left from under the heater and replace. Whilst there, check around for any mangled dried leaves as these will cause vibration type noises.

 

Flap motor replacement can be difficult and the first thing to do is have a scan as this will tell you which of the many has failed.

The most common one to fail is the air recirculation flap and you can check if it is working by switching on recirculation and noting the effect.

 

There are way of using the climate control buttons to 1) exercise and reset all flaps and 2) on some models get indication of faulty parts. 

However we need to know which variant you have and best way is to post a photo of your control panel.

 

There are many people on this forum who can help.

 

Many thanks for the information.I have added a photo of the controls.I will take it out for a drive tomorrow and check everything when at normal operating temp and report back my findings.I should be able to borrow a diagnostic tool.

 

Lots of information and videos on line for your version.

This one is not in english but shows the actions to do a self check and flaps reset.

This video shows how to do a full manual diagnostics check using the left temp control for menu and right temp check for submenu. The results are shown on the right display.

If you make a search you should be able to find the menu/submenu and data meaning in chart form but these do change slightly between model years and other VAG variants. Mostly they are for VW cars.

Great lots of info to check. Been out for a long drive . Two things checked . No errors come up when checked with OBD fault code reader. When ECO button is pressed the noise disappears 

Does the air get very cold when you dial both temperature knobs to LO when on AUTO?  

The fact that the noise disappears when when you press ECO (which switches off the air con) suggests the noises are due to low gas in the system. See suggestions by MicMac above.

Right

cooling system calibrated and blowers a lot more powerful but on auto and LO temp showing ,it’s not cold so looks like a trip to garage for a leak check / refill .

thanks for everyone’s help . On another topic what is the ESR button for? And should my puddle lights be built into the side mirrors? 

Thanks

ASR=Anti Slip Regulation (traction control)

Yes.

Ah great . Couldn’t find any reference in manual but probably just missed it 

Air con sorted thanks. Groupon voucher and 38.99 sorted.Just needed re-gassing.
