Hi guys, I'm new here and could really do with some help urgently! I hope I am posting this in the correct place. 

 

2007 mk2 Skoda Octavia and the boot won't open from the outside either with the key or the button to open the boot. I can however open it from the inside from the emergency release. 

 

My question is does anyone know what part I most likely need to replace? Is it the part number 1Z5827501D or 1Z9827511C (if you could google them to see that would be great).

Also, by changing either of these parts is it likely to mess up anything else central locking related? Any help would be very much appreciated!

Thanks!

I'm assuming from your description that your car is a saloon, not an estate?

 

The parts catalogue for an MY2007 Octavia 2 saloon indicates 1Z5 827 501 D as the lock mechanism - see HERE - but it's always worth a final check with your dealer.  You can also check by inspecting the lock itself, upon which there will be a part number.

 

Before you leap into a replacement lock, however, I'd take a careful look at the electrics which operate it; it is quite likely the fault lies in or around the operating solenoid rather than in the mechanics of the lock itself.  Check for dirty connections, corroded or broken wires and finally for a failed solenoid,  There's also a microswitch in the door handle which may be faulty.

Thanks for the reply @MikeTheThinker and yes sorry I should have said it is a saloon. Yes the part number of mine is 1Z5 827 501 D and that is what I was going to change first with hope that this would cure it - before I read into it a bit more and realized it could be a number of things! 

 

By checking the operating solenoid do you mean the part at the bottom (part number 1Z0 827 511 C) or if it is something else can you let me know what part? 

 

Is there a chance of messing anything else up by poking around at this fault? I would happily keep opening the boot from the inside but I need to get the car through MOT and I think this will fail?

Thanks again 

The boot latch (what you described as the bottom part) is the bit with the solenoid IIRC.  From distant memory it only has a single wire feed - but do check that - and if so it operates on receipt of 12v and completes the circuit to ground.  If this is correct then check the ground connections first (corrosion, loose fittings) and then disconnect the latch from the harness and check for operation with a 12v line.  If there are more than one connection to the latch DON'T put power to it as it is likely being monitored by the car's central control module.

 

As regards replacement, a power-only latch should be a straight swap but a monitored latch may need coding to the car.  I'd suggest asking the question on the Diagnostics and VCDS section.

Thanks again Mike. Will take a crack at checking these tomorrow. If you don't mind would you let me know what you would check from first to last with such issue? So I have something to go by when checking! Lol

You should check with a multimeter that it's getting 12v first. Maybe it has its own fuse also?

 

After that it's likely a part needing replaced.
