2014 Superb L&K

Hi, I've noticed that the controls for heated rear seats are locked out (padlock symbol on screen), could anyone explain how I can unlock this so that rear buttons for heated seats are active?

Thanks in advance.

Can you explain in more detail what is happening?

My 2012 Elegance is non-L&K, but it has rear heated seats as an option. And as far as I know the only way of operating them is via the buttons on the rear centre console - they can’t be operated from the front, and they’re not operated by touch-screen.

So are you getting a padlock symbol on the screen when someone presses one of the buttons in the back?

Are you able to read fault codes?

If I remember correctly there are three fuses related to heated seats: one for the front, one for the back, and another for the “switch” (which is a 7.5A micro fuse, IIRC). Worth checking all of them.

Thanks for the reply, Mike.

Both buttons in the rear don't appear to work. When pushed neither rear button illuminates. I've checked both fuses for rear and they seem fine. The two buttons for the front work and both front seats heat up.

Apparently it is possible to "lock" the rear controls to prevent children inadvertently switching them on.

When I press the AC and Front Vent buttons on the climatronic to access the menu the display on the RNS510 screen shows "Rear" with a locked padlock symbol above it

Ran a scan yesterday and no faults detected 😟

I went out and had a play with mine to see if I could reproduce the issue.

At first I wondered whether it was simply the rear window lock button on the driver’s arm rest, but that doesn’t lock out the rear seat heating. It also illuminates with an unmissable yellow light.

On mine, pressing the rear seat heating buttons cycles the three green lights next to each button, but nothing comes up on the RNS510 screen - unlike the front seat heating buttons which do show on the screen.

When I first got my car, the rear seat heater buttons were not working (though I don’t remember if there was any kind of padlock icon like you’re seeing). In my case it was a fuse, but not one of the two full-size fuses for the front and back seat heating (37 & 38). There is an additional fuse that’s physically smaller - I think it was number 46 labelled “switch for seat heating”. This one had blown; replacing it brought my rear seat heating back to life.

I’ll try to locate that fuse and pull it out to see if I get the same symptoms as you’ve got.

Thanks, Mike.

I checked the (I think) 5amp switch fuse and tested ok.

I'm pretty convinced the system is locked and requires VCDS to reset/unlock.

I have an iCarsoft scanner that doesn't show any codes related to climate, I'll have a look and see if there is anything under coding.....if not it's a visit to a dealer

Ah, okay - if it’s not that fuse then it does sound like a coding issue.

I have an iCarsoft reader as well. You can do recoding with it, but it’s not as friendly as VCDS.

Cheers, Mike 👍
