How do i change brake pedal switch on an A3 2007 sportback 1.9 tdi

Yes, it could be the brake switch which is located under the dashboard above the brake pedal assembly.

Usually attached to the pedal ,and generally it is a pin switch.

There's a brake light switch down on the top of your brake pedal. This switch actuates when you step on the pedal. If it goes bad you have brake lights all the time, or not at all.

Here's some instructions and photos (the instructions may be ridiculously offensive to some)

Did you check the bulbs into taillamps and fuses?If they are O.K. check brake light switch,located on the top of brake pedal with two wires connector.Disconnect the plug and short with wire.Check brake lights at the back.If O.K. check the switch.Some models use self adjusting switch.Just pull out the front part of the switch and put him back.

check brake light fuse. if ok. check to make sure you have dcv at brake pedal brake light switch mounted on brake pedal. if there is voltage present depress brake pedal and dcv shold be present on other terminal of brake pedal switch. if not replace brake pedal switch

There are a number of different causes of this problem. Check all glow plugs. Check glow plug relay. If both are ok....This may seem unusual...Check the brake light switch situated at brake pedal. A faulty brake light switch will cause the glow plug light to flash
Good luck with it

safety switch on brake pedal. common cause is a wire breaking off. there are 1 to 2 wires going to this switch. It is located on the brake pedal bracket above the foot pad.

check the brake switch on the brake pedal they go bad sometimes...its either in front of or behind the brake pedal

follow brake pedal all the way up
you have to lay on your back with a flash lite
on the pedal there will be a backwards bolt this adjusts the brake light switch for deplition or engage ment
if your missing that bolt brake lights will stay on you will find a hole there
across from that hole or bolt (if there) you will see the brake switch thats how the bolt presses the brakes on and off
have a buddy watch tail lights as you press the switch there in
its simple not much else needed
you probably missing the bolt find a flat bolt about 1 inch long 2 nuts these are adjustment nuts
