    Angry Brake light always ON

    Hello guys,

    First of all, sorry for my English, I am french, and in advance thank you for any help you could provide me to help me fix my issue.

    The issue :

    2 weeks ago, a driver stopped me to tell me that my brake light are on all the time.
    So i stopped and checked them, and he was right.

    I noticed that my right tail light had some burned leds. So I thought that was the issue, so I ordered a new tail light.
    Received the tail light, replaced the old one (DIY), the issue is still there...

    So after reading a lot of post on the forum I noticed that a lot of people had the same issue, and replacing the brake switch did resolve the issue.

    So I bought a new brake switch, replaced the old one (DIY), and the issue is still there,...

    So to resume, when the car is off, the light are off.

    When I turn the key, 2 or 3 second after the light (left, right and middle) are on and stay on no matter what I do.

    All the leds or ok.

    What I have done so far :
    - Replaced right tail light because old one had burned leds
    - Replaced brake pedal switch

    My car is a BMW E46 Coupé 330 CI of 2006.

    Here is the exact brake switch I bought : http://www.toutespiecesauto.fr/inter...-101-806-37596

    Here is the exact tail light I bought : http://i.ebayimg.com/00/s/OTAwWDE2MD...Yqgrn/$_57.JPG

    Anyone have an idea of what my issue can be ?
    If you need anymore information, don't hesitate to ask for.

    Make sure the metal tab near the brake pedal where brake light switch inserts is not bent. You may have to adjust it.

    I'm having this same problem, replaced the brake pedal switch and its still happening. I can't get my car inspected until I figure this out... any advice? All three brake lights are on all the time while my car is running. I took off the center console trim to look at the handbrake switch... it looks good.. but I don't know for sure that its okay.

    I have a multimeter with continuity check... any ideas of tests I could try?

    Thanks

    Check your wiring coming to trunk lid (upper right of trunk lid) could be a wire short.
