Climatronic error code

[fonkymonky]

Dear all,

my climatronic doesn't work. The pipes under the hood does not get cold and neither does the inside of the car (of course). After some googleing i found out that the climatronic could show some error codes when the econ- and recycle air-buttons were pushed simultaneously. However I have no idea what the code I get means...

In the left display i see 71^i or perhaps 71^1 and in the right 00^h.

Is there a table of these codes somewhere? Or do any of y'all know the meaning of this particular one? Any other suggestions/tips are also most welcome! :)

It probably needs re-gassing, if the gas has gone (happens when you don't use the AC) then the system will shut down automatically, take it to Kwik Fit and ask them to test it,

[JimC64]

More than a few of us have had similar stories recently, as seen / discussed here in this thread below......

A6 C6 Air Con issues (http://www.vwaudiforum.co.uk/forum/showthread.php?146333-A6-C6-Air-Con-issues)


As per DSG........the cheapest / simplest possible solution is to take it to Kwik Fit and ask about an air con check /re gas
They take around £49 for it but there is a caveat that is they don't get it 10% colder you don't pay a penny iirc

Its a good starting point and may resolve your issues................if not it will throw up some very useful info as to where to go next

Good luck

[fonkymonky]

Thank you for the tips! I don't live in the UK, though, but I guess we have similar companies here.

I also found this:
Re: Climatronic-Steuercodes (3724 Klicks) (http://forum.langzeittest.de/read.php?229,332067,439148#msg-439148)
and I had channel 10-1 showing on my way to work today. The pressure was between 4-5 bar - I guess that's low? Apparently my refrigerant is supposed to be named R134a and the charge level is 600 g, but what does that mean in terms of pressure in bars?

[RichardSEL]

"iO" is a common abbreviation in German for "in Ordnung" which means "OK" or "Operating Normally".

To access the information hold down the (ECON) or (AC) button and press the Window Vent button, release when both displays change to indicate zeros.
The left hand knob (Left Temperature) adjusts the Main Channel. The centre knob (FAN) adjusts the Sub Channel. To exit press the (ECON) or (AC) button.
The left hand number below indicates the Main Channel, the second number indicates the Sub Channel.
For example 19 – 0 is your digital speedometer in KPH, 19 – 1 is your digital speedometer in MPH. The type column indicates the type of data that is expected.

Yes, that's about the same as I linked to above, so I guess the question now is whether 4-5 bar is too low pressure. It seems like it, but could any of you confirm?

[RichardSEL]

When faced with this problem myself, and not knowing what many of the Climatronic self-diagnostic readings should be, I went through all the HVAC tests in VCDS. That seemed to set up the unit correctly. And apart from weak feet heating or cooling, AirCon seems to work well now.
Does your second fan turn on alright when AirCon is selected?
Until it does, and you've checked your HVAC settings, don't spend money re-gassing

[fonkymonky]

I unfortunately don't have VCDS. I have been thinking of buying it several times, but never gotten around to it...

[RichardSEL]

Just been to car, started it, and my 10-1 reading shows 3.2bar. This is from cold start

Aircon needed in Malmö? Nice!

[fonkymonky]

Oh, wonderful! Thank you! That means that I don't have to regas, and something else is wrong. I guess that's both bad and good... :) Thank's a lot for your help, RichardSEL!

Hmmm... back to square one. Anyone have any suggestions? What's this about the second fan? How do I know/check if it's working? Where is it even situated?

[RichardSEL]

Believe the 600g referenced is the weight of R134a. But I've never investigated fully, never needed to
Small fan is next to your main engine fan, just behind radiator. Switch on Aircon, second fan should run at operating temperature
Good Luck!

<later>
The 10-1 reading after 20mins run with aircon on mine is 9.6bar

[fonkymonky]

The small fan is working. I have been checking the climatronic values for a couple of days now and the 10-1 reading has been changing somewhat between 4-7 bars. I think the changing pressure is due to changes in outside/inside temperatures. The 10-0 value (evaporator temperature) is always hot, something like 30-35 °C, and the 10-2 value (liquid refrigerant temperature) is always exactly 20.0 °C.

Are those readings normal? Do any of you have some ideas? Is it time to get VCDS or should I try re-gassing?

[gazza007]

when I went to kwik fit he other day they recovered 575g from the system, which is very good as never been regassed, when it refilled after the machine had finished it cycle it was 600g. As you know from my other thread I had inadvertantly removed fuse 8 on drivers side. At least I got a free refresh out of it from KF as they couldn't lower the temp!!!!! Just need to sell the G65 sensor now, incidently I found a very good article on its function starts on page 48.http://www.google.co.uk/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&ved=0CDYQFjAB&url=http%3A%2F%2Fwww.volkspage.net%2Ftechnik%2Fssp %2Fssp%2FSSP_201.pdf&ei=roq3UYu_O4LfOKPsgeAD&usg=AFQjCNELh_aYCGNx7Im8Cac1fHY3daSC0w&bvm=bv.47534661,d.ZWU

[fonkymonky]

I have already checked the fuses. Strangely enough the scheme in the manual doesn't match the real life layout of fuses...? I have never before looked at the fuses and everything seems to be working as it should, even though there are fuses in slots where there shouldn't be any and vice versa. Is this something common or is it a misprint in the swedish manual? Strange, but the fuses couldn't be causing the AC problem since it used to work when the fuses were placed as they are now and I have checked them all and they are intact.

[gazza007]

I think the best way forward is a scan. It is worth paying out for the cable.

Mebe there is someone in Malmö that can check your system for beer tokens?!

[Teflon]

If you have to re-gas then there's the obvious question of where the old refrigerant went to.

There's a possible leak in the system, which is a pressure sensor (G10, I think). It's so common that if you are in the US it is a free replacement outside warranty, but in the UK it's about £80 for the part and about as much again to remove the bumper and gain access to do the job. Jag vet inte hur mika det kosta på Sverige.

[fonkymonky]

Yes, but wouldn't the pressure be 0 bars if I had a serious leak? As far as I understand it is "normal" with re-gassing every now and then because the systems are just not that good?

Det kostar säkert ungefär samma i Sverige. :)

[Teflon]

I can only speak from experience. Two 7 year old cars, similar mileage, both with climatronic. One has had no aircon problems. The other had to be regassed last summer, eventually traced to the G10 sensor. It's the only re-gas I've ever had on any car in maybe 20 years. It doesn't have to be a catastrophic failure to be a problem, just a little phfftttt now and then as teh car juggles along the road.

It's only one possibility for a leak source, but "just not that good" isn't a reason for the stuff disappearing. Your fridge never needs regassing and they are cheaper made than the average aircon system.

[gazza007]

G10 is oil sensor. Don't you mean G65 which is what I thought I had issues with. 21077

[Teflon]

Indeed I do. No wonder I can't pick decent lottery numbers.

[gazza007]

Ps it's for sale

[fonkymonky]

Thank you all for your help! I have made a lot of phone calls and googleing, but still I'm no wiser. Yesterday I decided to get VCDS and it shipped today, so in a couple of days I will know if it was money well spent. I'll let you know.

[fonkymonky]

Today I did a scan with VCDS and found code:

01809 - Actuating Motor for Temperature Flap; Left (V158)
http://wiki.ross-tech.com/wiki/index.php/01809

I guess this couldn't cause the problems I am having since the gas doesn't even get cold? VCDS also measured the pressure to approx. 5 bars just as the 10-1-climatronic reading. I guess this is kind of normal? What pressure readings do you guys get in VCDS? I also did all the output tests for the climatronic and found the left temperature flap motor to be working right then at least. Something else I can try in VCDS?

[RichardSEL]

Basic settings.
If the gas isn't circulating then you've got a pump fault.
In the self diagnostics chart I posted earlier, there's before and after readings to check
Post your Autoscan so we can see your settings and module report?

[fonkymonky]

Basic settings

Hmm... I'm not in front of the program/car right now, but as I remember it wasn't too clear to me what I could/should/dare do. Could you please point me to some more in depth info? Once again - thank you for all your help!

[fonkymonky]

It might be that I got hung up on this:

You should refer to the Factory Repair Manual for your particular car (or some other documented procedure) before "playing" with the Basic Settings function. Failure to follow the proper procedures can result in serious damage to the vehicle.

How much damage do you think I can do when "playing" with the AC?

[RichardSEL]

As been unable to find what the Climatronic diagnostic readings should be, did a listing yesterday
If anyone wants -- this is from my '06 SEL -- PM me your e-mail address and I'll e-mail it back in .doc format

Also included in the .zip package are two other .pdf files, think for Hella, found while searching

After an inconvenient computer problem I today finally got around to checking the car with VCDS again. My VCDS is in swedish, but I guess it is understandable anyway:

What are the central electrics and comfort control module faults. You haven't listed them.

[fonkymonky]

I didn't show the rest of the codes because I didn't think they were important to the AC-problem, but perhaps they are? It's something with the camshaft timing (should I be worried about this?), one light bulb, error concerning earthing at 18:38:00 on 2013.06.04 (I have no idea what this is, but we'll se if it happens again) and then an old code from dec 2012 about an un resonable signal from the trunk lid/lock.

After an inconvenient computer problem I today finally got around to checking the car with VCDS again. My VCDS is in swedish, but I guess it is understandable anyway:
<snip>
I also found this:
Adress 08: Klimatanläggning (3C0 907 044 AC)
16:17:02 Grupp 002: kompressor
0.820 A kompressor nuvarande (aktuellt)
0.820 A kompressor nuvarande (börvärde)
900 /min kompressor varv
1.9 Nm kompressorlast


What conditions was your car when this reading was taken?


Meaning that the current in the compressor is 0.820 A (as it is supposed to be) and the torque is 1.9 Nm. Is this normal?


If I know the condition of your car when that reading was taken, I can compare to mine. I don't know what is normal


Tried the basic settings, but it only said "Endanschlaege lernen".

I don't know what this means "learn end stops"


<snip>I can't fint the self diagnostics chart you mention?

It's message #4 in this thread without my readings. Or in the .zip I sent you with my readings (italics) and the two .pdf files

I don't think you have a climate fault. I think you have an electrical fault some where else. First. Check fuses SD15, SD39 and SC27. Don't just look. Test each one with a battery and a bulb. If you can't find them, test all the fuses. Your fault looks like a failure of the onboard supply control unit but checking should start with the fuses.

I have already checked all the fuses using a bulb (ALL of them, since the manual didn't match reality...). What's the next step? I was actually first suspecting a simple electrical fault since I have had mice under the hood off and on during the winter. Have seen droppings, tracks in the snow and even caught several with traps placed under the hood during nights. Imagined they chewed off a cable or so, but I haven't been able to find anything by looking around. Any suggestions where to look? I don't expect the earthing problem to be due to mice, because it happened 4th of june and the mice moved elsewhere when it got warmer outside.

The temperatures both in the car and outside was approx 20 deg and the motor had been running for, say, 10 min.

Yes, I google-translated it and I guess it means that VCDS is trying to find out where the different flap motors stop. But it just keeps doing this. Isn't it supposed to do something else also? How long could something like this take? How long should I wait for something else to happen? What happened when you did basic settings?

I have of course looked at the documents you sent me, and am very thankful for them. I must have misinterpreted your previous post. I don't understand what you mean with before- and after-values to check? You mean your post with the cold engine pressure and the pressure after driving a while? Looking at your document again I compared your values of channel 11 with mine:

11 – 0 Power setpoint mA engine off: 000, engine on: 820 (same as VCDS)
11 – 1 Power actual mA engine off: 000, engine on: 820 (same as VCDS)
11 – 2 Power maximum mA engine off: 000, engine on: 820 (same as VCDS)
11 – 3 Compressor PWM Digital (0-200) engine off: 00.0, engine on: 82.5
11 – 4 Power offset compressor engine off: 8.8, engine on: 8.8
11 – 5 Power value Digital engine off: 45.7, engine on: 45.7
11 – 6 Compressor code engine off: 05, when turning engine on: 12 and then changes to 00 when running

I guess there might be something interesting in 11-6, since you have code 06 instead. Do you have about the same values as me with motor running?

Check the fuses I mentioned before to make sure they actually have power with ignition on. I suspect you have lost a live feed or an earth.

Check the fuses I mentioned before to make sure they actually have power with ignition on. I suspect you have lost a live feed or an earth.

I just checked all the feeds for the fuses using a test lamp, and they all showed voltage between the body of the car and the fuse. However, with this method I don't know if there is a break in the wire between the fuse and the consumer, fx the compressor. Is it safe to test the with a voltmeter in the fuse's socket? Can this cause some kind of short circuit? If this is OK I guess I will know if the other part is earthed and therefore check the rest of the wiring? But it could of course be earthed BEFORE the consumer if it is broken... Hmmm. What's next?

[martin1810]

Voltmeter is safe to use generally. You shouldn't cause a short circuit with one. You need to find the climatronic control unit and check it's power feeds. It should be fed by the three fuses I mentioned earlier. VW wiring is often different to circuit and fuse diagrams so nothing is easy. If you need wire diagrams send me a pm through my site.

[Bernas73]

Good day to me are having this same problem. Who was it?

[pmamsantos]

Dear all,

my climatronic doesn't work. The pipes under the hood does not get cold and neither does the inside of the car (of course). After some googleing i found out that the climatronic could show some error codes when the econ- and recycle air-buttons were pushed simultaneously. However I have no idea what the code I get means...

In the left display i see 71^i or perhaps 71^1 and in the right 00^h.

Is there a table of these codes somewhere? Or do any of y'all know the meaning of this particular one? Any other suggestions/tips are also most welcome! :)

Hi. I have the same error code in the Climatronic system of my Passat B6 from 2007.

Does anyone knows what this code means?

The problem with my climatronic seems to be a distribution heat problem.

Air conditioning seems to be working fine, but on the left side of the car there is only cold air, meanwhile on the right side there is hot air.

BR.

[RichardSEL]

Give me your email address and I will send you the table and other useful information I have collected
711h = 01809 decimal is Actuating Motor for Temperature Flap; Left (V158)

[pmamsantos]

Richard
Thanksfor your help, it was definitely very useful.
Analyzingthe symptoms, it should be a problem on the left side of the system, becausethe hot air only flows on the right side of the car.

Next step is define what is the problem with the Left Temperature Flap Motor.

I'll feedback on this.

[janvaneijck]

Hi,
Unfortunately, I experience a similar issue with the aircon mainly on longer trips. It feels like it loses its power to cool after about half an hour driving.
Well, being a noob I found this thread and tried the first thing:
To access the information hold down the (ECON) or (AC) button and press the Window Vent (http://shop.ebay.co.uk/?_nkw=window+vent) button, release when both displays change to indicate zeros.
And there already it goes wrong for me. If I press the ECON button together with the Window Vent button then the left display goes to 00.0, but the right one yesterday went to 13.6 and slowly went down in 5 minutes to 12.4. Today I tried it again and it showed left 00.0 and right 8.4, went down to 8.2 and went up to 8.3. And this with keeping the buttons pressed, but also after having released them.
What do I do wrong?
For the rest I do understand that I can use the left and center dials to read out a value in the right display, but I cannot get both displays to 0 by pressing ECON and vent button.

Can someone explain me what I am doing wrong?

[RichardSEL]

I don't know what you mean by "window vent button". Quoting from my .doc:
"With engine running and after a run with air con on, hold down the ECON button and press the re-circulation vent button <this has a 6 and a 9 on their sides symbol on it that I can't reproduce here> In a normally operating system you should see both displays eventually change to “iO”. This is a common abbreviation in German for “in Ordnung” which means “OK” or “Operating Normally”.

[janvaneijck]

Quoting from your post #5:
To access the information hold down the (ECON) or (AC) button and press the Window Vent (http://shop.ebay.co.uk/?_nkw=window+vent) button, release when both displays change to indicate zeros.

In other forums I have read that it is ECON with the arrow up button, which made sense to me as the up arrow indicates the Vent(illation) area for the front window.

If I should have interpreted your post differently then tell me, because that also could be part of my problem :-)

ECON + Recycle button result in iO / iO

ECON + Window Vent/up arrow result in an accessible menu with all the 20+ options, but when I press them both together both displays never turn to 00 00.

Hope this helps, and that you can help.

[RichardSEL]

My post #5 in this thread was translation from the original Italian now three years old :confused: There was also another German language list so I put the best together.

The diagnostics listing has been updated since, so PM me your email address and I will send you the latest copy.

That line for the up-pointing arrow should've read "face vent button". Using Econ and face vent button together you can dial in to monitor any specific parameter you want to see and remain reported.
I have listed what you can set using the left hand knob and the right hand knob. Also listed are what my readings are (with system working normally "iO") on the right hand window. That listing is at the end of the .doc. Using that method they will not turn to 00 0 or "iO" -- just stay to what you have dialed.

For example 19 – 0 is your digital speedometer in KPH; 19 – 1 is your digital speedometer in MPH. These figures do not have the higher than actual speeds’ weighting that your analogue main speedometer displays, so are real MPH and KPH.

>>If I press the ECON button together with the Window Vent (http://shop.ebay.co.uk/?_nkw=window+vent) button then the left display goes to 00.0, but the right one yesterday went to 13.6 and slowly went down in 5 minutes to 12.4. Today I tried it again and it showed left 00.0 and right 8.4, went down to 8.2 and went up to 8.3.

I don't know what 00.0 is, so can't say what the right hand window is reporting

[janvaneijck]

I sent you a PM and once again thanks for your help.

I expect that 00.0 in the left display is channel 00 with program 0. You above describe the same as 00 0.
