My wife has a new 2018 Q3 Sline. She previously had an A6. Apparently the new Audis now use a different seat heater mechanism. After about 10 minutes the seat heaters automatically change from level 3 to level 2. Additionally the heaters aren't very warm even on level 3. My wife has a back condition and the seat heaters are a great help for her.

Does VCDS provide the ability to disable the automatic heat reduction on a 2018 Q3?
Does VCDS provide the ability to increase the heat output of the seat heaters?

I will buy whatever kit is necessary, so if someone can answer these questions and (hopefully) point me in the correct direction I'd greatly appreciate it.

My other alternative is to trade a 200 mile car for one with properly functioning seat heaters. Yep. It's that serious.

Someone please save me a lot of money! :) Thanks

What happens if she turns it off and back on again?

There's been a lot of grumbling about low output on seat heaters in various VW/Audi cars of late.

As for knowing what can and can't be done with VCDS, that's kind of a Catch-22. Without seeing exactly what control modules are installed in the car (and they change a lot!) it's really difficult to know.

If you're willing to post your location, perhaps there's someone nearby who already has VCDS that could get a scan from your car...?

I'm in the columbia/baltimore MD area and would be happy to get a scan and post it. From googling this does seem to be a common complaint. Wish I would have known before we bought.
Thanks for the reply. Perhaps you know of some independent shop that uses VCDS in the area??? I'd be willing to pay a nominal fee to see if this is possible. It really is important for my wifes comfort.

Thanks again

I was able to try-before-you-buy, by renting a cable for a week from an ebay-er for only $30. That got me comfortable with how VCDS works and what it can do. Then I finally bought my own from RT last week. Maybe a short term rental would work for you?

I'm leaning toward just buying the VIN limited version for 199 and sending a scan. I have an additional question. If the scan indicates that it is possible, would that require a software update? Or is this something where I can flip a few bits using long coding? I've seen this can be done with the Q5 using something called an Adaption in the HVAC and/or Central Electrics sections. (Sorry if my terminology is wrong - I'm still learning)

If it can be done, it would likely be changing one or more values in Adaptation, or tweaking some coding bits.

Ill have a look in my Tiguan. Not going to be a 100% match with a Q3, but technically its very similar.

Just a thought - if it's THAT serious, then have you tried contacting the dealership/tech center? This brand new car must be under warranty (1) and yet dealership is the one who knows their brand cars the best (2).
Besides, I think such a query will not cost you anything.

They say it is working as designed. And of course they are correct. Hence looking into VCDS to see if we can tweak the design to work better for her.

Just adding something totally off kilter, but there may be health issues caused by heaters under bums that they are trying to mitigate..

Anyhow - good luck..

Well I went ahead and purchase the cable. Here is the auto scan. Would be forever grateful if someone can make sense of this and tell me if disabling the seat heater reduction and/or increasing the heat output is possible.

Sorry, but time machine retrofitting, especially from DeLoreans, is not supported yet ;)

OP is now Verified. Moving to tweaks.

I'm on laptop, on generator power after an ice storm, so can't research it properly right now.

Only if he finds someone renting a V2 or HEX-NET. The older HEX+CAN will be missing a lot.
Isn't it the case that model year 2019 onwards is declared as fully incompatible with a HEX+CAN in general?

Hi Uwe,

I hope you have power restored and life has returned to normal. I just wanted to check and see if you've had time to do any research on this. Thanks for any update.

Hah! Here's the fun we had to deal with that day;

Power was off until late Monday.

To be honest, I had forgotten about it.

I've just done some digging. You have an old-school (non UDS) Climatronic module in that car. I don't see a way to directly influence the behavior you wish to change using a scan tooo, but... It looks like the seats have temperature sensors in them. Please have a look at these measuring values in the 08-HVAC module:

021: Heated Seat (Driver)
1: Position, Thumb Wheel, Range: 0...6
2: Request, Heater,Range: ON/OFF
3: Temp. (Act.), Driver (G344)
4: Temp. (Spec.), Driver (G344)

022: Heated Seat (Passenger)
1: Position,Thumb Wheel, Range: 0...6
2: Request,Heater, Range: ON/OFF
3: Temp. (Act.), Passenger (G345)
4: Temp. (Spec.), Passenger (G345)

If it works the way I think it does (based on feedback from actual temperature sensors), then it should be possible to fool it somehow. I think the first step is to take a log (from cold) of these values and let's see what's happening there as it warms up.

-Uwe-
