In other cars I have owned the power to the 12v socket in the dashboard has cut out when the ignition is switched off, however it doesn't seem to do so in my Fabia. Is this something I can adjust in the settings? I'd prefer to have the power cut out when the engine is switched off to avoid a sat nav/ any other device plugged in to the 12 v socket draining the battery.

I noticed this on mine the other day. I left my phone plugged into the car and locked car and went in house. Returned to car after 10 mins and when I unlocked it and opened the door the phone beeped to start charging. I think it cuts the power to the 12v socket after a short time. But power starts again when car is unlocked. But don't quote me on that. Will try it again later.

The 12v socket isn't ignition switched however it will be monitored by the car to detect any power draw.

This will then cut the power at a certain time after the engine stops running to avoid discharging the battery.

Unfortunately it can't be changed in any settings.

The 12V socket is constantly on, regardless of whether the key is in the ignition or not. I believe this is so with most VAG car brands.

You can surely take your car to a local car electrician, thogh, to have them switch the socket wires so that it turns off once the ignition is off.

Contrary to popular belief, the Fabia III 12v socket is not monitored by the car. Therefore, if you do have something like a sat nav/dashcam/mobile/etc., plugged in, you could come back to a dead battery in a few days.

 

You could hardwire your sat nav into the fusebox so that it only comes on with the ignition. Alternatively, hardwire a battery discharge prevention device (e.g. Lukas LK-290) into the fusebox, and plug your device into that. It will then cut power at the pre-determined voltage.

Are you sure about this? The other day I left my phone plugged in and left the car. When I went back and opened the door the phone made the 'starting to charge' noise and the screen lite up with the battery logo. This surly indicates the power was cut (this happened when I opened the door, not starting the ignition, which in some cars does cut power everywhere).

Did you use the USB socket or 12v cigarette lighter socket?

P77 of the owner's manual has a caution, part of which states that:

"Connecting appliances when the engine is not running will drain the battery of the vehicle!"

Yes I know that, but when the door is closed.

However, I have made a mistake! My phone was connected to the USB, not 12 volt. My apologies for this!

The 12v(olt) socket is constantly on with all Skoda cars but this isn't the case with a newish VW Golf - The 12v socket disconnects after a few minutes when engine turned off

 

In the boot of my Skoda Superb - I use a Volton ZR1220 split relay between the boot socket and my electric coolbox used when I drive through Europe - so I don't have to remember to disconnect when parking up

The 12v socket is not permanently live on the 2013 Citigo, it is definitely ignition switched and all the earlier models I had, Fabia Mk1, Octavia Mk1 were the same. The Fabia Mk2 went to permanent live,

No Mk1 Fabias have anything but permanent 12V to the ciggy lighter according to the official current flow diagrams. Some models of Mk1 Octy have a relay-switched lighter socket, but many don't.

I can confirm that Audi, VW and SEAT also switch the cigarette lighter socket off when ignition is turned off - which seems to be common practise nowadays, the AA solar battery charger has been made with this in mind as it gets sold with an OBD2 plug and crock clips.(no cigarette lighter socket!)

I stand corrected , was advice I got from my dealer when asking the question as I would have preferred switched live

 

My MKI Octavia, Superb I & Superb II were/are all permanent live
