This is a very easy and quick job. I had never attempted this before and was able to do it in under 20mins. This is for an Audi A3 2005 engine code BLR.
Thinks you will need.
1. A narrow head Philips screwdriver
2. A small socket and ratchet set
3. A torx head screwdriver set
4. Replacement switch
5. Friend to assist checking of the brake lights
Firstly remove the side panel from the dash on the drivers side. This should be done with the philips screwdriver and should just pop off. Instructions for this are in the car manual. You will see the fuses and near the front a small bolt screw. There are three of these retaining the lower fascia of the dash. Undo this one. The other two are in the footwell at the lower end of the dash - one left and one right. Use the ratchet and I think it was a 10mm socket. Ease the fascia down and pop off at the top. A bit of gentle pulling should do the job.
You will need the torx screwdriver to remove a retaining screw for the heating venting. Behind this is the switch, sitting just above and infront of the brake pedal. Twist anticlockwise about 30-45 degrees and you will feel it come free. Remove. Again use the small philips screwdriver to depress the locking mechanism for the plug and remove from the switch.
At this point do not adjust the brake pedal or press it down, lean on it in any way until the switch is in place.
Put the new switch through the hole and rotate 30-45 degrees until it is properly seated. You should hear it click in to place. No setting is required beyond this as it should self adjust. Ensure you hear it click!!
You can now push the brake pedal down and you will see the plunger move out of the switch.
You will need your friend now to check the lights are activated when you press the pedal. If you have no one to help reverse the car near to a wall or white garage door and check for each light in your mirrors.
Replace the fascia.
Job done.
