Skoda Fabia 2009 boot won't open sometimes

[Lugy]

Hi all, got an intermittent fault with the OH's little Fabia ('09), at times the boot won't open. It's one of those solenoid efforts - what was wrong with a button and linkage?!

I've tested the switch, and I'm 100% it's okay. The boot latch is getting power but occasionally won't get a signal to activate. There's no pattern to when it will or won't work, seems totally random. The switch is definitely sending the signal to what sounds like a relay inside the dash, though none of the relays behind the fusebox control the boot and I can't find any other ones (not keen on pulling out the dash!). Oh and when the boot won't open, there's no click from the dash.

I'm at quite a loss now, anyone know anything about these?

All the you describe symptoms point to the relay causing the problem. Given that you say it clicks when it works correctly, it shouldn't be too hard to physically locate it.

If this vehicle is a hatchback there is a very good chance that there is a broken wire in the tailgate harness, the opening and closing of the tailgate causes this problem, look for the tailgate loom from roof area to tailgate and check it out

Cheers folks, I've had a good look at the wiring, that was one of my first thoughts, all seems well.
I can get to the main relay board but it's none of them, where the clicking is coming from I can't see though.
I've since read that these cars may have a control unit for the boot and need diagnosed with VCDS! I guess that's progress!

Could be weak solenoid ? i see it a bit, the solenoid is weak and sometimes wont pull the mech if there's any strain or load on it, listen to the hatch where the solenoid is when the button is pressed and listen for a weak hum , if the solenoid hums and there is power to it it needs a new solenoid, the coils will have burnt out in the windings, you could test the solenoid resistance IF you can find what it's ment to be ?
