    So I fitted new brakes today (discs & pads) so the brake warning light has gone off.
    And guess wot, another has appeared same day!

    Coolant warning light.

    Coolant is full, no issues with over heat.
    So I presume its the bottle sensor.
    Can I buy the sensor or is it a new bottle?

    Part nos pls?

    Thanks.

    The pins on the wear indicator are pathetic...and the clip that holds the two parts together ain't much better.
    I wrapped a slip of tin foil in to each of the female stakes on mine as it went off with every puddle.
    Then a wrap of tape to ensure both halves of the connector are tight up.

    Gentle scrape of the metal pins inside the Coolant reservoir with a screw driver usually helps.

    If not pull it out and soak in scale remover for 5 mins (no more)

    Otherwise...6 cylinders should be 8E0121403D
