Air con not working

[Gregie]

When you get the io on the screens if turn the

Knobs( can't remember which one ) it changes the screen. I get io as well as 02h 0E5 which I have no idea what it means. Have a fiddle with the dials and see if changes to a code. Also if you hold down the ECON and re circ button and use the left temp dial to change number to 19 and the middle dial to change number to 4 it should give the compressor speed in tenths. There is a thread on here somewhere about it I'll try finding it ASAP for you.

[nought2sixty]

Superb guys, thank you. I was twiddling the dials blindly trying to get the code to change but nothing happened. I'll try it a bit more methodically tomorrow and see what happens.

My mechanic got someone in to regass it, no idea if they did a pressure test or not. Hence why I think getting it checked at a good specialist is the way to go. I'll investigate the two mentioned tomorrow

The air con on my 09 LE estate has just packed up, car fortunately still under warranty. Booked into dealers D M Keith Leeds today. Dealers say there was no gas in system, so have re-gassed it with dye in and

have said that the evaporator behind the dash board is suspected to be at fault. Apparently they have to dismantle the entire dashboard to get to it! and require the car for 2 days! But will loan me a car.

Anyone else had this done before? What problems do i need to look out for ? other than the dash rattling for ever more! LOL

Hi, I bought my Octavia last week with a faulty AC did a quick check myself.

Turned the clima to LO and the radiator fans speeds up, center bolt on compressor was running so the compressor was still working but the valve inside the compressor was stuck.

Removed the valve after removing the gas from the system.and cleaned it and got the valve to move, now it is working.

Just a matter of time befor it stucks again due to particles inside the system.

Valeo compressor on my one.

Should the radiators fans be spinning all the time with th AC as I noticed that mine don't unless the car is hot but then it's on off on off. I assume te smaller fan is the AC one of so I've yet to see it move at all. Causes to this?

[blueR36]

Well mine was in today for an air con service, it packed in when it was hot, ( worked perfect till then ) they serviced it then scanned it, then rang to tell me it was not working! yes I know, that is why it is having a aircon service. They plugged in to diagnostics and somehow the ECU codes have gone haywire and need to be flashed. Now Skodas computer has gone down and also I might lose my map, ( can be re flashed

[octimark]

Has anyone got any recommendations for a supplier close to Sheffield please?

[octimark]

Part Number on my unit is: 1KO 820 803N

Does anyone know which other part numbers will fit?

Is the unit the same for the petrol as it is for the diesel?

[napperd]

My AC packed in a while ago now, with the hot weather we've had recently I could do with it working again.

I haven't try the self diagnostic yet, must give it a go. For a while the radiator fan would come on intermittently and stay running for a few moments after the engine was turned off.

This went on for weeks but I have not noticed it over the last week or so, does anyone think that this could be linked to the air-con issue?

 

Thanks

I used a garage called Autoworks (0114 272 3410) which I found by accident when looking for Technik - Both behind the Royal Standard pub close to the railway station in the centre.

 

Price was £541.20 All Included - brand new Denso pump, fitting, re-gas, VAT

I know this is an oooold thread but would like to add my recent experience. 

 

59 plate Octy VRS FL diesel.

 

Aircon stopped working a few months ago but it was winter so wasn't too worried.  Then car started making a weird coughing noise when starting.  Last week decided to investigate and, after reading horro stories of £1300 bills for new compressor, decided to take it to my local Formula 1 Autocentre (first time she's been anywhere non-Skoda).  The guys there were very good. Took me out to the car to show me that the internal bearings of the compressor were shagged (brown staining on belt and face of wheel and the centre nut protruding out). So new compressor. 

 

All in including replacement compressor and regas was £519. I also got a better quality compressor than the original. I'll find the part number....

 

Overall, a lot for keeping the car inside cool but much better than expected and very impressed with Formula 1.

Does anyone know what 0E5 02H means

[primoz86]

I also get error:

0E5 02H

and

524 04H

 

How can I find out what this mean?

[bell222]

I also get OE5 02h as well does any body know what this is thanks

For the aircon to run the engine cooling fan must be running. On the C3 with CC this starts automatically. If there is a problem with the fan then the aircon will run but only for a few moments as the condenser which is located in front of the engine rad will overheat and the system will de-clutch and shut OFF. check by looking under the front bumper when the a/c is selected ON.Or you may contact to AC Repair Cypress ,they are efficient and are very potential in their service.

[sadexpunk]

just been doing a search and found this thread so using it instead of starting another.....

 

my aircon doesnt work either, had it regassed a couple of times over the 4 or 5 years ive had it (57 L&K) and its been lovely and cold for a week or so then warm again, so rather than regas a third time i thought id look into what may actually be the problem.  been reading the 'self diagnosis thread' too and have got the same codes as above, OE5 02h.  has anyone come up with the answer for this, do we know what these codes mean please?

 

thanks a lot

[Diversion33]

Hi guys

I have a 56 L&K and am having a/c trouble again. Less than 2 years ago I had the compressor replaced and it was brilliant all last year. We've come to use it for the first time recently and got nothing but ambient air. Ive done the self diagnosis thing and it shows 4CF 07h. Any ideas please

Many thanks

[kton200281]

Could just be low refrigerant as it won't kick in if there is not enough in the system (to avoid damaging the compressor), not sure on the code though sorry.

I had a dying compressor this year. The symptom was that the AC worked fine when it was cool out but, if I left the car in the sun in the summer, the AC wouldn't kick in until I'd driven for 5-10 minutes. Regassing didn't lower the AC output temperature or improve the fault.

 

The price my dealer quoted for replacing the compressor was much keener than some of the numbers I've seen on here so it may be worth shopping around between main dealers.

 

Another thing I heard from another Octavia owner is that you should make sure you run the AC for at least 5 minutes a week (turn it down to LO) all year round or the seals dry out because the AC oil isn't going round the system and there's a tendency for it to leak its gas out and for parts to get dry and stick/wear out.

Same problem Papfox.

Have 2008 Octy 2.0TDI vRS with aircon that only works on cloudy cooler days and at night, and when the sun and heat is out, ambient to warm air I get doesn't matter if I rotate the nob to low.

Aircon kicks in for less than 30 secs and turns off, turns on again and turns off.

Tested with diagnostic tool no DTC's, and compressor RPMs seem fine when turning aircon on, but notice that evaporator temp takes long time to drop to 9/10 celsius. Getting furious with this as it has been like this for two years. No leaks detected, it's got gas as a leak test was performed and all was OK. I always have AC on even during winter as it helps to defrost windows on a rainy day.

Done tests with diag tool, resetting AC system and all flaps,then leaving AC on until I see a wet floor under the car which means AC is working, then back to warm air again. I even have hit the compressor and the expansion valves lightly with a rod and hammer to see if it was due to a stuck valve.

So it might be the compressor then as I was also trying to figure out if these compressors had clutch to engage like others do.

Seems like every time I do a reset on the AC system it works for a couple of days but not that cool air that you would expect.

If compressor is the matter here, any better brand that anybody recommends?

what does this mean?:D

Hi all, I’ve recently fixed my AC, maybe it’ll help someone. 
 

My 09 tdi cr vrs started blowing warm air, had it regassed, still no cool air (Kwikfit don’t charge if it’s still hot which was handy). So was likely the compressor as it held pressure but the engine note didn’t change when I turned the AC on. I also didn’t get any fault codes from my OBD11 app (great app btw). Did a bit of research and the common cheap and easy to fix failure modes of the compressor are the shear plate - not a clutch but it provides drive from the pulley to the compressor shaft and the compressor solenoid valve. These compressors don’t use a clutch, instead diverting the gas with said valve, so effectively acting as a switch. 

 

I inspected for the first potential issue by removing the drivers side front wheel and arch liner and checking if the drive shaft splines had stripped or not on the input shaft (I found some guides on YouTube how to check for this, dead easy to check).
 

It wasn’t that, so ordered this valve https://www.ebay.co.uk/itm/142899171603?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=Kg4_M3XrQxa&sssrc=2349624&ssuid=IG3wQ3dxQIC&var=&widget_ver=artemis&media=COPY. I did have to check the part number on the compressor and old valve first though as there’s a couple of different types, I’d recommend doing the same. It’s fairly easy to access under the car on your, you just need to lift the front and remove the under tray. The valve is secured with an internal Circlip that you need angles pliers for. I should point out that I asked a local garage to remove the gas for me and then regas it when I was done. I got this at a slightly cheaper rate as all the gas was still there so was only charged for labour. And hey presto it worked!

 

Might be different for some, but it’s worth checking if you think your compressor is knackered. I’d like to point out that whilst I am a mechanical engineer, I just found it all on Google and YouTube so any DIY mechanic can do it. 

 

Hope this helps someone!

Thanks for sharing your experience, the solenoid is known to go bad from sediment clogging the mesh filter.

 

You can strip and clean or replace as you did but the gas handling is the snag for most DIYers.

Exactly. You just get a strange look from the garage folk till you explain the entire situation haha.
