Fresh from my v3.2 software update, most things have been working correctly, and at last the WeConnect (sorry, VW) app is giving me more useful features, like "where the heck did I leave my car?")

Yesterday, a couple of minutes into a drive, I felt rather warm. The heated seat had turned itself on and the cabin temperature had set itself to maximum. I tried to turn them down, but each time, the temperature display started counting up and the heated seat indicator seems to be cycling between different settings.

Did the usual things, cycled the ignition, reset the Infotainment panel, but I was still being roasted. VW dealer said it might be a problem with the touchscreen (guessing at phantom inputs here). Gestures are off, so no chance of any wild hand movements triggering it.

Anyone else been baked recently?

Mine did this a couple of times after 3.2 but seems to be behaving normally now!
If it helps the cabin temp sensor is the small lump (looks like an off LED) just above the centre console net. I guess this being obstructed might make a difference but who knows!

Mine has been doing this over the past few days and seems to be getting worse. During a 15 minute journey today it kept increasing the temperature by itself (at least 20+ times), so I was almost constantly needing to turn the temperature back down, where it would remain for about 30 seconds. Cycled the infotainment system twice, but no difference. It even did it when parked on the driveway having gone into park.
If it doesn't sort itself out I guess I'll need to call VW and get it into a dealer, but the visits I've had previously have never inspired confidence.

Mine does the same. It seemed to be worse in the Summer, when the central console got very hot
But that may have been a coincidence

Quite a lot of other error codes, Parking brake, front sensors
We're hoping it's sorted in the next update

I am sure someone will correct me, but I don't think Parking sensors or Parking Brake errors are caused or repaired by any software issues. Do you mean Parking brake or manoeuvre braking? If you have a parking sensor out, then manoeuvre braking will be unavailable also.
Does the parking sensor screen show a particular segment with an exclamation, you may need to book that in and be prepared to foot the bill if they are damaged.

I've just had to have the inner front two sensors replaced due to stone damage.

Mine started doing it today. Also, VW connect doesn't connect to car anymore - i wonder if they are connected?

I haven’t so far, but I think it happens when the the sun is on the back of the infotainment through the windscreen on a hot day(it gets very hot) and the unit thinks the touch sensors are being pressed (hence cycling through the heated seat options and turning the cabin temp up every few seconds. I have pulled the fuse on the heated seats so they can’t actually come on. When it did it again today on my drive after solar charging, I set ‘rapid cooling’ and as the temperature came down (I had to swipe the temperature down a few times) , it stopped doing it. I shielded the back of infotainment console from the direct sun with a small card and left the car. I came back later and it didn’t do it - but the sun wasn’t as hot by then so I will repeat the test again tomorrow if it is hot again.

Maybe you could try pre-cooling your car from the app as a matter of routine and see if that stops it. And/or attach something behind the screen to shield it from the sun a bit. Appreciate this not a good solution long term!

Yes, that might be a work around.

Long time lurker...

My wife's did this heater thing again today. It hadn't done it for a while but I wondered if it was related to the current "heat wave". On a short journey I ended up turning off all the temperature controls as it suddenly getting hot was v. annoying! It started doing it last year after the 3.2 update. Out of the corner of my eye I could see a message popping up regulalrly as if something was trying to make something happen. I wondered if the ambient temperature was messing with the touchscreen somehow.

This does sound like it could be something to do with the problem. I'd noted that it happens on hot days, so maybe this is just another of the many design faults built into the panel (like the unlit temperature controls.)
I suppose putting a bit of kitchen foil on the back might help, but it's a bit of a noddy fix... wonder if VW has brought out a better panel yet?

New cars now have a better panel with backlit sliders and faster operation, yes. It's also slightly bigger. Variations of it have been on ID.4/5/7 for a while and are currently being put on new ID3s I think. Whether it's more heat resistant who knows.

Backlit sliders... I can't begin to imagine what numpty at VW designed a panel where you can't see the temperature controls at night, a 100-year retrograde step. No doubt they just thought "ach, zey vill use ze voice control so ve don't need to bother..."

This is my work around. A £10 medium sun screen from Halfords which i leave folded and resting on the back of the info unit when parked up on a hot sunny day. So far , so good. The back of the info unit remains cool even though the cabin temperature is high when you get in the car. The AC cools th le car down quickly.

Wonder if they do a customisation service? Something like "ID.3 bug shield" printed on the front, maybe?
