RS162 MY15.5 air conditioning

[wfdTamar]

Hooked up my VCDS to see if there was anything I could do and found this which I tried and it possibly has made a difference (haven't driven enough yet). It recalibrates the flaps inside I think. You hear all the flaps running their full range of movement and fans going, then it turns off.

I know when I do this on my Saab 9-5 it works wonders if it's skew wiff.

Yes, that seems to have made a difference. Haven't noticed any warm air BS since I did it.

I got mine checked at 15k service recently. Predictably they couldn't find a fault, I gave them very specific details on what was happening but just got the "monitor it" line and that there are more settings in the menu that I need to use (even when I told them setting it on max cold full fan A/C on that it still would blow warm air).

I asked if there were any firmware updates or reset that they could do but nothing they could see.

And of course it did it again on the way home, not as badly though maybe because it was only 25deg outside. I found it happens less if I keep the setting on very cold and don't give it a chance to cycle the A/C level.

So....looks like either go back and forward to the dealer to give them another crack or fix it myself.

Anyone that has had a "software" fix by a dealer can you please post the details so I can tell my dealer how to do it? I don't have vcds so can't do the basic setting myself.

I have exactly the same problem, and it normally kicks in when the stop start activates, went to the dealer they gave me the same spill "monitor it"... so if you get any results please share the fix, thanks!

Well I haven't take. It back in yet, been too busy.

Yesterday I drove from Melbourne to Albury and back, around 7 hours of driving with a couple of short stops in between. On the way up I had no issues, but I had the temperature set to heating for the majority of the trip up.

On the way back it wouldn't cool properly on and off for the whole trip. I got fed up and one point and set it to max Lo temp and got a digital thermometer I had in the boot.

Here you can see that the air temp coming out of the vents is slightly higher than what the car measures outside. The probe is inside the centre vent.



Later after the system deciding to respond and actually send cold air through the vents:


I didn't stay cold though, after a few minutes I set it back to 18-20 deg and warm air started to come through again. I tried setting it back to max Lo and couldn't get it below 16 deg. I gave up after around 15 mins of trying between auto and manual settings. The same sort of cycle repeated every half hour or so.

The temperature measured inside the car about 30 cm back from the centre console was approx 26 (varied around 1 deg during the time I was messing around trying to get cold air).

Can you post a pic of your aircon "setup" settings?

Mine is finally fixed I think!

Took it for a long drive on the weekend after the service last week and it stayed cool the whole trip.

Mind you I had to take it in 3 times before they agreed there was a problem.

Here are my service notes if it helps anyone:

I don't have a pic of both setup screens but it happens when set on strong, Medium and light profiles.

I tested with auto recirc on and off makes no difference either.

This weekend I drive about an hour trip mostly freeway and some suburban streets. After a few minutes drive with the temp set at about 19 (22 deg outside) I noticed it wasn't blowing cold air. I tested again and found that the air out of the vents was hotter than ambient, even though the setup screen graphic showed cold air coming from the vents. I then set it on Lo for the remainder of the trip and the air never got cold. At one point I measured this....



I set the profile back to medium because I was sick of getting hot air blasted at me when on the strong setting.


On the drive home I put the temp back to 19 and I started getting cold. I checked the air temp coming out of the vent was between 5-8deg which I would expect to be normal when trying to cool.

Thanks for that info, I will mention it to the dealer. I did check the pipes one time after it happened and it felt to me like one of the pipes was frozen solid even though I wasn't getting any cold air.

Out of interest you in Melbourne? Just wondering which dealer it was.
