Infotainment not working

Feb 18, 2020

Hey, I’ve got a 2016 mk3 Leon, my battery went flat earlier and since charging it up again the infotainment screen won’t turn on. I’ve changed fuse 10 and 12 in the fuse box behind glove compartment and this has done nothing. It literally won’t turn on at all. Everything else works fine in the car electrically. Any advice?

thanks

That’s a tuff one. I would do the usual checks by removing the head unit and testing for power at the harness first. That is strange tho.

Sometimes when they overheat they won’t turn on again until they are cool enough.

mine has done this a few times then 10 mins into the journey jumps back into life

Does the screen in the middle of the dials say 'Infotainment powered off'? I'd get an OBD scanner and check for errors first.

Aha, had this recently and didn’t know why it had done it, Ta.

I cannot wait for this to be a major flaw in the mk4 when you can’t turn the heating on cause the infotainment is too cold / hot
I thought the MK4 had sliders for the heater? Which is slightly less idiotic than having the controls in a touchscreen.
 

Seriously?

Seriously? I thought there were sliders under the screen?
It looks like it in the intro video, but it's not clear if they are 'mechanical'. And (although it may just be my eyesight playing tricks) it appears that they don't light up at night!

I think there is a de-mister button on the light switch too but its in that awkward a place you are more likely to turn the foglights on instead

Yes, it's as if all they've cared about is what the cabin looks like with little thought on how easy the controls are to use.

Hi guys sorry for late reply been busy, haven’t yet had time to get the screen out but it’s still not working so can’t be a overheat issue. I’ve noticed the usb/power socket in the glove box also appears to not work so I’m guessing this is likely not a screen issue?

thanks

If you don't have a USB socket in front of the gear lever then i'm sure that your car is not a 2016 model, also if you have a CD player with SD card slot in the glovebox then you don't need to remove the screen to test for the power supply, it's the unit in the glovebox that needs to be checked.
