Please help!!!

I have a B5 A4. I replaced the brake light switch several months back.

Yesterday, it took me a couple times hitting the brake to get the car to recognize it and let me shift out of park. On the way home, I recognized that when I hit the brake the lights weren't coming on. Well, I thought it was the sensor again. When I looked under there, I noticed there are two very similar looking sensors connecting to my brake pedal. I can't remember which one is the brake light sensor. Also, what is the other one?

Thanks ahead of time!!

I need to get this figured out so I can go to work tomorrow!!!!

 

it's either a bad brake switch or there's sumthing wrong with ur shifter. ewll there's a little sqaure by ur shifter with a slit on one side of it. if u open that and stick ur key in, it'll do that same thing as applying the brakes to shift. that's a temporary solution so u don't get stranded though. get the problem fix, don't delay it lol

 

I can't find that square you're talking about. I was hoping that there was one, but no dice. As far as the switch, do you know which one? There are two one above another.

 

i have no idea wut switch sry. and ur right, doesn't seem like there's a little square thing on the audi. pm auditech79. he for sure will be able to tell u

 

Most likely it is the brake interlock switch. It is what prevents you from taking the car out of park unless the brake pedal is pressed. Unfortunately, I don't have my Bentley with me, so I can't give any more details.

 

I think you need a third pedal.. That would solve your problems.

 

K, found out the the second switch is for the cruise control and has a vacuum line attached to it. I'm going to change out the brake light switch one more time and see what happens!

 

Don't break it.
