Third brake light removal (from memory). Task = 1-2 Hours depending on hand size / patience.
If you have the Cupra R spoiler, you will need to remove three bolts (inside the boot), one of which is concealed by the plastic surround which is inside the top of the boot. The bolts have little rubber helmets on them.
Undo the bolts (i think they are either 8mm or 10mm) and you will find there are two plastic clips in-between the three bolts (exterior to the car - in between the spoiler and the roof, it should just pull off.
You will have a long wire going from the brake light into the big grommet in the centre of the car roof.
Remove the grommet and unplug the connector, making sure the connector doesn’t fall in too far or you won’t get it out again. (when putting it back together make sure you use abit of silicon around the grommet to stop any water getting in)
To remove the third brake light from the spoiler, you will need to remove the two pieces of black tape, which cover to entry holes. You will then need a long thin Phillips screw driver to undo the two screws which hold the brake light in place (right inside and at the back of the spoiler). Once these are undone you must unclip the centre clip of the brake light unit itself which holds it into the spoiler.
PM if your stuck. At the first instance, i would just remove the spoiler and unplug the connector, get someone to put their foot on the brake and get a multi-meter in the connector holes.
