Default Brake Switch - Faulty

Is this an easy fix? Im short on cash these days and from what i hear this is a $30-40 part. The dealer wants to charge me $200. Does anyone know where a good step by step instructions might exist?

Are you referring to the switch attached to the brake pedal that tells the brakes to light up?

If you are then I have added a removal step-by-step process:

I can't seem to get a part number for the switch.

Default Thanks!

Thatís exactly the switch I was talking about.
Thanks a ton for the instructions.
This looks pretty straight forward. Have you ever done this before?
I havenít poked around much under there. I hope itís easy to get to. I imagine that will be the toughest part.

Thanks again!

No. I haven't had to replace one before, but I'm sure it wouldn't take too long. The hardest part will be getting positioned so that you can see AND use your hands. Good luck!

clemsongt thanks for the diagram. very helpful. i tried to just lube the one that is faulty. the brake lights arent staying on anymore but now i have my ABS and traction control lights on in the dash. Does this mean i need to splurge the 5 bucks and buy a new brake light switch? will the new brake light switch turn off those lights, or is this anyother problem?

I would certainly doubt that this switch would have anything to do with ABS or traction control. This switch is simply there to know when to turn the brake lights on. Definitely not an expert in this area though.

I went to dealership today to buy the new brake light switch. On the way there I had my ABS and traction control lights on and as well as the car just didn't seem to spool up as normal while accelerating through 1st and 2nd gears. Bought the $4 switch and installed it in the parking lot. After installation, all lights went off and the acceleration seemed to be back to normal. My thoughts were that possibly the brake light switch is part of the circuit for the ABS and traction control. Which means if one of these switches go out, you disconnect the circuit. At the end of the day, my brake lights don't stay on when my car is off.

Did your lights come on in the middle of the night? I have this problem and I was pretty sure that was the issue but I haven't heard much rumbling of this issue before

No, my lights would just come on randomly. Like i would look out the window and my brake lights would be on.

Default Getting access to brake light switch?

I have a 2005 A4 2.0T and I purchased a brake light switch as Iím having the same issue.
I saw the instructions for how to replace but Iím having trouble.
How do you remove the driver side storage tray to get access to the switch?
Does anyone have the diagram that shows how to remove the tray?

I'm getting a loud beep and a yellow "Brake Light" error message display on my dash. During the beep it also says "Centre Brake Light"...the centre brake light works sometimes which leads me to believe that it isn't the light itself (but I'm not ruling that out just yet). Could this possibly be a faulty brake switch or being caused from the cold winter weather?

Note: the other two brake lights are working properly and this is a 2005 a6 not an a4

Thanks in advance!

My center brake light did go out with similar symptoms. They had to replace the LED panel.

Default Worked like a charm

Just replaced mine after going through the head ache of unplugging my battery every time I left my car alone for more than 4hrs for the last 3 months - worked great. Easy to do - hardest part was getting the dash back on and aligned correctly around the headlight switch - but I'm ****.

I actually had it in the shop in November, and their electrician turned my car away because he didn't like working on Audi's. Blessings in disguise - who knows what they would have charged me for this 10 minute fix!

Watch for that clutch switch - I accidentally took that one off too, but thankfully it didn't break.

Oh - and DON'T order the part from ECS - they have the wrong part listed for the A4 B7.

As I stated earlier, the Brake Light is coming on due to the Centre Brake Light not working but as of today, the ESP and the ABS lights are now on as well...does this all point to the brake light switch??

lozts - this post was originally on how to replace the brake light switch, sounds like your question should go in a new post or maybe try finding one that match your symptoms. Another user posted saying that they had similar symptoms and had to have the LED panel replaced. Don't know if that helps you.

Just wanted to say the faulty brake switch thing happened to me with my brake light staying on every night after work. When I researched DIY it seemed like the part was cheap but the procedure not so simple. I had my mechanic do it and glad I did. The part was $28 and I watched him struggle getting his face and hands under the dash, removing a lot of stuff. Unless you enjoy this I recommend having your pro do it. It cost me $50 and 20 min.

Since it would have taken me hours and I would have screwed it up, it was def worth the fifty bucks. I was off to work in no time where I could actually make the dough to fix the rest of my Audi issues, ha!

I'm beginning to realize that nothing on this car is easy to fix! LOL. I spent a little over an hour this weekend plus a few skinned knuckles changing a dumb headlight bulb--and that was on the EASIER side. Still beat paying Audi $76 to do it, though.

Yes so true. As it happens right after I wrote that my driver side headlight went out too, with that headlight dipped error message. Joy! I read through some of the threads and my head started to spin. Good on you for figuring it out, I haven't looked at it yet. These repairs add up, oy!

I heard someone say (prior to me buying my A4) that if you can afford to buy two Audis, you can afford to own one. I think they might have been right. Overall, mine's been fairly reliable, but there is definitely a higher cost of ownership on these--even when they're working right. Fortunately, it's worth it.
