Hi, I have a 2012 Fabia 1.6 TDI estate, I often leave my dog in the car for short periods, I have followed the instructions in the handbook for turning off interior sensors for the alarm but I'm finding it doesn't work, the switch to disable interior sensors is red, when I press it in the light goes off but when I release it it goes back red, should it stay red or should it change colour to show it's activated?,

From my manual.

Switch off the interior monitor and towing protection monitoring
– Switch off the ignition.
– Press the button  on the driver door ⇒ fig. 42.
– Lock the vehicle within 30 seconds. The interior monitor and the
towing protection monitoring are switched off.
The interior monitor and the towing protection monitoring
• You can also switch off the interior monitor and the towing protection monitoring,
by deactivating the safe securing system ⇒ page 40.
• When the ignition key is removed or a door is opened, the symbol in the button
lights up red.
• Lighting up of the symbol in the button does not confirm that the interior
monitor and the towing protection monitoring are switched on.

Does anyone know how to replace the switch on the drivers door

Appreciate this is an old thread however I wanted to share a bit of info I just gleaned: from this link https://www.b-auto.net/skoda_fabia-1/central_locking_system-747.html

God bless em.

 

Warning light in the driver's door

After locking the vehicle, the warning light flashes for around 2 seconds in quick succession, afterwards it begins to flash evenly at longer intervals.

If the vehicle is locked and the safe securing system » page 46 is not operating, the warning light in the driver door flashes for about 2 seconds fast, goes out and starts to flash evenly at longer intervals after about 30 seconds.

If the indicator light first flashes fast for about 2 seconds, then lights up for about 30 seconds continuously and then flashes slowly, there is a fault in the central locking system or in the interior monitor and in the towing protection » page 50. Seek help from a specialist garage.

 

 

I know this doesnt answer your question but bare with:

Basically my mk2 1.6 tdi has got a red light like yours in the drivers door to turn off the interior sensors, mine lights up red as I open the door, I press the button, it goes out but comes back on again, after a short time it goes out permanently. I then move about in the car and the alarm doesnt trigger.

 

Before placing any faith in the button I have to first repair the horn unit in mine because it doesnt make any noise, the indicators do flash however which is whats telling me that the interior sensors are indeed being turned off..HOWEVER the section of text in red above is whats happening to the little red light at the top of the drivers door card so clearly I have a central locking problem which is maybe why my Interior Sensor Off button is showing symptoms like yours of being lit red when logic would suggest it shouldnt be untill pressed ? thoughts ?

 

Oh ive also read on this forum that the central locking, little interior sensor button, alarm horn etc are all wired together and sharing earths inside the door .....

I think the red flashing light they are talking about there is the one beside the window. My switch on the door just goes out and back on again when pressed.
