Hey Guys,

I own a new Q7 (4M) and I'm looking for the coding for the HVAC piece that drops the heat from 3 to 2 as per here: (This information was from an A6/A7 2016 Forum Post on another site). I figured it may be possible on the Q7 4M.


Change the time before the heated seats auto-change from level 3 to level 2
When the heated seat is set to full (level 3) it will only stay on full power (level 3) for 10 minutes before automatically dropping to level 2. To increase (or decrease) the amount of time this takes, go to
Module 08 (HVAC) -> Adaptation -> drop in down box select the option 'time until heated seat stage withdrawal from 3-2'.
Enter a new value. Save.
The default is 10, which is 10 minutes. I set it to 15 minutes. Change it to zero to prevent it from auto-switching from level 3 to level 2.


I have a HEX-NET and Ross Tech VCDS 15.7 but the option "time until heated seat stage withdrawl from 3-2" is not listed in the drop down in "Adaptation" when I connected upto the car.

Does anyone know what Long Coding (Byte/Bit) this change does and I can try it directly in Long Coding instead? Is that even possible?

Cheers

Andy

Looking through the adaptation channels for your HVAC module (which seems rather different than the 4G types) I don't see anything promising looking either, nor in the coding data...

Uwe, thanks for info. I guess it might be possible, as other new Audi models do it, just not the Q7 4M. Be great if we could find those cars and get a scan done, would that help in any way?

Just because some models allow for something doesn't mean other models do, even if they are newer or more advanced.

Does anyone know if this tweak is possible on a 2014 Audi A4 allroad? My girlfriend likes her seat really toasty and is constantly having to switch from level 2 to 3.

Does anyone know if this tweak is possible on a 2014 Audi A4 allroad? My girlfriend likes her seat really toasty and is constantly having to switch from level 2 to 3.
Checked German-language sources and I'm not seeing anything in there either, sorry.

Just because some models allow for something doesn't mean other models do, even if they are newer or more advanced.

Yep, totally understand Uwe, just figured it might be worth a shot. I'll keep on hunting

Thanks
