Boot lid stuck in cold weather - mechanics issue

[skollop]

Hi

 

I got an issue with my Skoda Fabia 1.0 Tsi 95 Combi from 2020.

Both this winter and last winter (only two years I've had it), I've had issues with the locking mechanism in the boot lid. When temperatures gets sufficiently low, somewhere around -2 degress celcius, the locking mechanism is stuck and doesn't work. I can open the boot lid from the inside using the manual opening (getting a screwdriver in a small hole), but it's impossible to unlock from the outside. So it's definitely not frozen to the rubber edges, it opens perfectly fine from within. When using both the normal button on the key and the one to open the boot lid only, nothing happens. As in, there is no sound from the mechanism inside. 

From my experience, after using the car for some time and allowing it to heat up makes me believe that this is a temporary issue only when the locking mechanism is cold. 

 

Does anyone know if there is something I can do to fix it myself? I have some warranty from the dealership, but it's far away and I would love to save all the trouble from going there.

It might help to spray the door seals with a silicone spray and also the locking mechanism also open the fuel filler door and clean the inner and outer surfaces and spray. I have had the door freeze shut if water gets in.  Joe

As previous poster has put but I'd use GT85 (£3.50 from Halfords (web) at the moment for 400ml can) as this also has lots of others uses on the car, home, shed, pushbikes and it's PTFE and not silicone (for those that worry about the paint).

 

Unfortunately it's no longer a British company but part of a large invasive American corporation but that's the UK now. - https://gt85.co.uk/

I tried with some lock-oil on spray that can hand high freeze temperatures on the mechanism, but it was still frozen this morning. 

 

As said before, I'm 100% sure it's not the rubber seals around the trunk that gets frozen. It's super easy to open with the manual opening from the inside. I'm sure it's an issue with the locking mechanism itself

Well at least you've tried the easy first step, nothing lost with correct lubrication should do no harm but good.

 

So now as you can open the boot from the inside it suggests it's the switch or wiring or further back so a multimeter and/or a VW compliant scan tool.  Here's list of VCDS (and other) owners that might be able to offer help if required. - Briskoda VCDS Owners Map (click me)
