    Hello all,

    Ive been having trouble recently when both rear light clusters are causing the dash warning light to come on due to the plug which connects to the bulb holder being partly corroded.

    I contacted my local bmw dealer who said they had replacement plugs at aprox £4 each in stock.

    As the plug has about 7 wires connected to power all rear lights does anyone know how to disconnect wires from old plug and connect them to new one.

    Thanks again for any help provided

    Liam

    The correct tool to do this is (types a description, deletes it and retypes, deletes again) really hard to describe in text!! You might get one on egay. If you can it would be well worth it!

    what you have to do is, as you look at the plug, on the biggest sides there is a plastic tab covering each pin. Snap these out.

    Next, as you look at the plug from the end that plugs in, poke something small thin and flat into the connector along the top and bottom of the pin to free the catches that hold it in place. The pin will then slide out of the back of the connector.

    When you buy your new plugs get replacement wires for the ones that are burnt out (usually the earth pin) Good luck!

    There is an extra earth wire you can put in that stops this from re ocouring. its becoming very common

    I am most definitely having this problem now as well...will be checking my earth wire to this cluster when I get home if the sun doesnt go down.

    How do we add an extra earth wire....just slip it in (pls avoid pun here) where the original earth is going and to a screw somewhere in the boot?

    Any advice is greatly appreciated as always

    Oli

    If I understand correctly the corrosion means a bad earth inside the light cluster, the brown ground cable feeding the cluster is tapped into and an additional exposed metal part of the cluster is grounded by this, sortof bypassing the corroded ground in the socket.

    EDIT: Pics see here on BF!!
