Hi all.

I’ve searched all over but can’t find a way to manually open the boot of the mkiii. It stopped opening today. It opened as normal when I got out and when I came back nothin. There is no click and it won’t open with the key or the internal switch. When I press the boot button there is no noise at all. There is a video on YouTube but that is a mkii and not the same. 
 

On mine there is a hole on the plastic part above the latch but I dare not poke around too much in case I break something. 
 

so anyone how do I release the catch so I can at least check it out in case something is jammed in although nothing is visible from the inside or out. 
 

Thanks

Correct hole.

 

Unlocking the tailgate

Fig. 174 Emergency unlocking of the boot lid The boot lid can be unlocked manually in an emergency.

›Insert a screwdriver or similar tool into the opening in the trim. ( the hole you noted )

» Fig. 174 as far as the stop.

› Unlock the lid by moving it in the direction of the arrow. 

› Open the tailgate. 

 

You push the screwdriver blade in and then push the handle down, with the inserted blade going up.

 

HTH.

 

Thanks, AG Falco

 

Thank you. I feel a bit stupid as I looked in my manual at locking an d unlocking but missed the next page in the index regarding emergency procedures. So figure 174 in the online manual and it us in mine as well figure 195. Off to try now. 
 

Thanks again 🙂

Ok so that worked. I wonder what could have gone then? I suspect I’ll have to remove the cover and see if it’s the switch. It is quite odd as my old Astra played up for ages before the switch eventually failed. This worked perfectly all the time and then just failed. No warning at all. I take it the switch just touches two contacts together so I should be able to simulate that to prove if it’s the switch?

Mechanical only, so if you have no power it will still work.

 

So does your boot switch have power going to it?

 

Thanks, AG Falco

I’ll have to take it apart to get to it tomorrow if it stops raining as I don’t have a garage although I do have a multimeter. Cheers

Just for your info, doesn't alter the great info AG Falco has given you.

 

The online copies of the 'Owner's Manual' are just pdf copies of the paper printed copy you have (beyond a certain point they change but not for your year).  There are two pdf copies for 2016, 05.2016 and 11.2016, both have 'fig 195' but on one page number different.

 

You can find the pdf copies here. - https://manual.skoda-auto.com/004/en-com/Models

I know and that’s why I thanked him in my 2nd post. I’m grateful for all help.

I tried to have a look today and managed to measure on the pins to the switch zero and 12v and on the 4 pins to the lock/servo 2 with 12v and 2 with zero volts. I had to go out then. I tried a short across the cable to the switch 2 pins but that didn’t work although the door was open already so maybe it wouldn’t. I struggled a bit on my own as it’s not easy to hold the door half open. I want to put my meter across the switch while someone operates it to see if I get a short. The switch is nicely sealed in so no point in removing it until I test in situ which is something I failed to be able to do on my own. My wife is here tomorrow so she should be able to help. 

I removed the switch and tested it indoors and it worked fine. I put it back in circuit and tested from the back of the connector and when the switch was depressed it went from 12v to 0v which I would expect connecting the two together. I tested to earth and between the 4 terminals on the lock and no matter what combination when I pressed the switch nothing changes. Since there are two 12v lines going to the lock I tested between them and got 0v as expected as no potential difference but even with the switch closed this didn’t change as did nothing on any of the other terminals. 
 

I’m a bit lost without a diagram now. Could it be software since that allows it to work? I looked through the fuses in the manual and can’t see an individual one for the boot. I’d expect there to be no power to any of the connectors though if that was it.

Just re read what I have posted.

 

The emergency unlocking of the boot lid is mechanical only.

The boot switch on the outside of the boot is electrical.

 

 

I think if you have the engine running/ignition on the car locks the boot automatically?

This stops 'tealeaves' opening the boot while you are stopped in traffic.

There are also options in the infotainment as to what opens when you unlock the car?

Don't think this will help but it might be worth checking / changing the setting.

 

Thanks AG Falco

Thanks.

 

yes I know it’s mechanical only, as I just physically shove the lever. 
 

With the testing I’ve done then I suspect it is either.

Broken wire back from switch. I suspect not though as I have 12v and the other is earthed.

If there is a relay involved then that is faulty.

Software related so I’ll take a look at the locking settings. It’s got to be worth a go.

software related where something has crashed. Is there a way to do a reset?

 

Thanks

 

Can I get a wiring diagram from anywhere? 

After reading a bit I think I’ll see if a wire has broken where the cable goes through the tailgate. Google searches for diagrams or even how it works are not revealing g anything. I don’t even know if the switch trips a relay first. Anyone know? Cheers

Any update? Did you manage to fix the problem?
