    I have an E46 330d and this is probably a frequently asked question but the warning light on the dash for the rear lights stays on all the time and there is nothing wrong with the lights. Is there a loose wire or something that needs checking???

    One side or both?

    Have you checked all lights? including high level brake light, rear fog and number plate lights?

    If yes then check the plug connection on the bulb holder itself as the earth wire connection is common for burning out.

    It could perhaps be your brake-light switch that causes the warning lights on the dash... I looked through the wiring diagram system recently and came across this text:

    Brake light switch
    The electronic brake light switch only operates as from terminal R ON.

    It has its own voltage supply.

    If the brake light switch is OK, it assumes a high-resistance setting when the ignition is switched off, i.e. it sends a signal as if it were operated. If this is not the case, this indicates a short to ground and the messages "brake light defective" as well as "rear right lamp defective" and "rear left lamp defective" are output or indicated in the pictogram in the instrument cluster.

    The light switching centre recognises the "operated" status if there is a break in the line. If is recognises the switch interrupted for longer than 10 s as operated, the light switching centre then also makes use of the vehicle acceleration signal. If a conflict is then detected, the above-specified error messages are output.


    I haven't experienced this problem myself (yet!) , I just wanted to share the info about this feature in case it should turn out that your earth wire connection is ok.
