I think the plastic where the wires click inta maybe causing issue. I dont remember much issue getting mine off now, just remember it popped off and i hadta flip it over to access the light screws

I'm not sure which part you're refering to, could you clarify or mark it on a picture?

See below might nt be right id need ta see it when u have screws off, ifya want ta give me a call on whatsapp or something when ur doing it again might be easiest

Thanks for the info, I'll have a look tomorrow and get back in touch with you.

If you're able could you send me a dm? I don't have enough activity on briskoda yet.

Same issue my end post ur number here and il send u a message delete after

Hey guys,
It took me some time, but managed to replace the 3rd brake light last weekend. I'll try to write a summary on the different parts that needed to be removed to get to it to help any further attemps along.
However, it took ages even with the help of someone as we didn't really know how to remove each part and didn't want to damage anything, if you're not comfortable I recommend going to a dealer or other garage to get it fixed.

Everything is at your own risk, be especially carefull when working with connectors of electronics or near electronic parts, to not damage them.

(The following video is on a Octavia 3, but can you some idea of the removal of the big plastic piece: https://www.youtube.com/watch?app=desktop&v=uXg_Cw9DWtA)

Step 1:

Get the replacement part (V5E7945097 I believe). I recommend you also get new screws, I had to do with cleaning two that were a bit rusty.

Step 2:

Choose a day with a mate and plenty of time.

Step 3:

Remove the big part of the boot interior plastic (5E7867975A), be carefull to remove the connector of the button for the electronic boot before completely taking it off. This plastic part is mounted with 16 metal clips (image 1).

Step 4:

Remove the smaller plastic that's around the window (5E7867605), this has two screws (visible when you've done step 3), 11 clips and needs to be pulled to the inside to undo all clips (image 2 & 3).

Step 5:

Unclip the connector of the brake light and washer jet that's mounted in the spoiler (https://youtu.be/nH4BN3Fib1U?feature=shared&t=176). Also release the cableholder for the wire set to get more room to work by pulling it straight out (image 4 & 5).

Step 6:

Add protection (masking tape or cloth) to prevent damage to spoiler and rear of the car.

Step 7:

Remove 11 screws and nuts (image 6). A very small ratchet is highly recommended, or one can manage with a Torx 25 allen key for the 4 screws in the square holes.

Step 8:

After closing the tailgate, lift up the spoiler slowly although with some force to click it off. It is still somewhat held in with 5 red clips (image 7).

Step 9:

Replace brake light (I didn't take pictures, this step is pretty easy though as it is just 1 wire clip, 4 bolts and maneuvering the clips of the brake light out afterwards).

After replacing the light, connect the cables back on the spoiler and to the car to confirm it works. I even went as far as to check all other lights and the washer nozzle.

To mount the parts do the steps in the reverse order. Make sure to keep track (as good as possible) that all clips are correctly clicked in. I am to this day not sure if I got them all, although there are not rattles or weird bump in the plastic.

If there are any questions, feel free to get in touch.
Thanks to the people in this topic that helped by their posts here and especially @naialsl for his support.

minor adjustments to text, grammar

Just wanted to reach out and say I’ve created an account just to say thank you for this.

Your guide was the most complete and helped with what was not a massively straight forward job.

To anyone else looking for the solution this is it. Couple of things to add, on point 7 “a very small ratchet is highly recommended” I just want to reinforce that you will need to find the smallest depth right angle T20 you can for this as it is really fiddly. Als the initial trim removal requires a bit of grip and rip as the back tabs are really difficult to get out.

Thanks again @TimoB

Awesome to hear it was usefull! ☺️

My toolbox also was enriched with a tiny cheap ratchet (Image 7, top left 😜)

Well, the center brake light on my car have some water drops inside already. And this is only after 6 months after production.

I guess that during the first service this must be replaced under warranty.

However, @TimoB, very useful guide, thanks a lot! Definitely will have it mind if needed in future (after warranty runs out).
