After plenty of searching, and reading of different links etc, I thought I'd write a quick guide and stick it all on here, as I did this this morning. I have a 2003 LC, but when I called the dealer they needed the VIN code to ensure I was given the correct part. You'll see fromt the pics that the new part is considerably different to the old part. Old part in my car (2003 LC) is 1J0 945 511E New part for my car is 1C0945 511A RDW I also did this blind, before I actually read any of the other guides around, so it may be slightly different. Seat Leon Cupra – Brake Light Switch Replacement Tools needed – • 1 x Phillips Screwdriver (medium) • 1 x Flat Blade Screwdriver (medium) • 1 x T25 Torx Bit • 1 x 2” Extension Bar • 1 x Ratchet Handle • 1 x Torch Time taken – 30-45 mins 1. Remove the fuse panel from the side of the dash. 2. Identify all of the screws you need to remove. There are 7 x Torx head screws, and 2 x Philips heads screws in total. 4 x Torx screws in the fuse panel, and 3 on the underside. The 2 x Philips are located on the bonnet pull panel. 3. Start removing the lower dash screws (left to right). The first two screws are longer than the others. 4. Then remove the 2 x Philips on the bonnet pull handle. 5. Follow up by removing the screws in the fuse panel. 6. Once all screws are removed gently remove the lower half of the dash by pulling it down, and out towards you. 7. Once you have enough room to get your hands in, reach behind the light switch and remove the plug from the dimmer/headlight adjuster switch, and then the light pane switch. 8. Pull the dash out completely. 9. You should now be able to see the brake light switch. 10. Twist it anti-clockwise until loose, then pull out of its socket.
