Heating on my s line has gone funny

[:: blade ::]

The heating on my s line is stuck on hot for the driver side even if you put it to cold on the climate control. Passengerside is fine and can still change from hot and cold on the climate unit. Any idea. Ive looked online and some says its heater sensors behind the headunit and some an arm that has broke behind the dash. Hope to get it fixed now its staeted to get warm now

Hope you can help

you need to check the motor and arms behind the center console, they can malfunction, best way is to remove the trim to expose the control arms etc, then try all settings on the climate control and see which move properly and which dont.
Its just another one of the B7's little annoyances with age.

Aye get the glovebox removed and you'll see the actuators with individually colour coded arms

With the car running you should be able to seem them move when changing settings on the controls

It could be the motor on drivers side footwell, you need to get it on diagnostics to confirm cause there's a few & messing that up can create bigger issues.
