Climatronic problem

[passatpout]

Well mine was struggling with moderate sunlight and not overly hot days recently, driving between Canowindra, Parkes and Dubbo. Outside temp was 28-31, reasonably pleasant to walk around WP Zoo, but the car was really struggling to keep it cool, even with the dial set to LO. As soon as the sun started going down, the car became a freezer, with temp set at about 23....

AC performance is just one more of those things that's really disappointed me with my car...

Shhesh, I'd end up with hypothermia if I did that! There's got to be something wrong with it. I live in Queensland, hot and humid and before I did the small mod blocking the sunlight hitting the dash sensor, it was just too cold and fans blew too high.

BTW, it's still working a perfectly now. Just set it at 24 all day every day, and it's spot on.

Clip I applaud you and would have nominated you for Aussie of the year but sadly I am being treated for frost bite!

damn frostbite! but thanks anyway Gray Ghost, and I was hoping to get a crack at it this year too!

No worries clip don't be to disappointed, perhaps you could take up acting that seems to work?

I have not been able to try out your incredible fix just yet, reason being I also live in Qld on the Sunshine Coast and as you are aware it has been just a little wet and hot plus you can throw in a little bit of overcast weather which makes it just the right conditions for a little bit of "crouch pot cooking" geeeee, did I say that?

Well before I tackle the stone wall of VWA I plan to watch this great movie for some inspiration it's called "The Spy That Came in From The Cold". I think it's about a German agent that came across to the good guy's because he had a MK6 Golf and not one of those cars that 007 drives with a working Climatronic system?

Anyway as it's Aussie day I must go and get the beer from the back seat they should be chilled enough by now?

I will keep you all advised of my progress or perhaps lack of with VWA.

Hi, any action from VWA - not that I expect there will be. Deny deny and the customer will go away.......

My MY12 Tiguan has exactly this problem, and dealer 'can't find any problem' when servicing.

I'll try a few covers over the sensor - wonder if flyscreen or shadecloth (things I have in the garage) will work at filtering the sunlight - which seems to be causing the problem. Will let you know.

Hard to believe VWA can't or won't address the issue, but car companies are as bad as banks or insurance when it comes to customer care.

Cheers.

I had a customer with a similar issue in a passat.

I also found it to be caused by the sensor over compensating.

I spoke to tech support about the issue and we fixed it.

The climatronic is set to HOT COUNTRY, which means when sunlight is on it cools dramatically. They led me through a procedure and we set it back to standard. It was a change of the hexdecimals. I dont have this written down, as it was done live over the phone..

My new passat wagon has the same issues. Haven't explored this with the dealer yet. Which dealer are you using? I am in Brisbane too.

Thanks

Send Buzuki on here a PM.

He may be able to shed some light on the blizzard-like air con problem.

Hi Brycem

I took the car to Bryan Byrt VW service, Mansfield. Hope to get back to the service manager for a chat in the next few days.

Today, I constructed a patented "VW Climate Control Regulator" - essentially a small cardboard box 70x40mm which on its top has 2 layers of window tint film. I sat the box on top of the IR sensor in the middle of the dash and went for a drive. Set the Climatronic on Auto at 24 degrees and went for a drive in very bright sunshine with outside temperature of 21 - 22 degrees. The Climatronic worked very well indeed with the fan on 2 bars and a gentle amount of air coming through the front vents. I lowered the Auto setting to 23 degrees and it again worked well. My next test (hopefully tomorrow morning if bright and sunny) is to go for a drive when the outside temperature is about 17 degrees and see how it performs. For a car of its expense and technology, VW should have a software modification suitable for our climatic conditions.

Silly question, new to this site, how do I send a PM to buzki?

Regards
Matt

He's posted in a few Climatronic/air con threads in the Passat section lately.

When you spot one of his posts, click on his name, and there'll be an option to PM him.

I had to stop using the aircon in my car..the smell is now unbearable. Its like a vinegar smell..sometimes smells like rotten fish left utside for days.

Anyone found a fix for this? I tried using Glen20 spray but only lasted one day then the smell went back again.

Anyone from Sydney that can help?
