    Icon5 405 Ext. temp. gauge problem

    My 405(S2) temp gauge is faulty - started showing 69 and 70 degrees for a while and now just flashes --. I suspect the external sensor,which is in the bottom of the NS mirror, but how do I get to it? I think that the painted cover on the front comes off but don't want to wreck it in the process. I would be grateful for any clues.

    Hi

    This is a mirror off job, Taking the coloured cover off wont help you.
    Open the window, Unclip the black plastic cover trim inside by pulling it off with your fingers & remove the Torx 20 screws to get the mirror off the door.
    There should be 2 electrical plugs to unplug aswell before mirror & door part company.

    A helper holding the mirror is usefull & dont lose the gasket between the mirror & the door.

    It could be a duff sensor, a dirty electrical connector plug or the earth points on the bodyshell.

    I would check to see if theres any water inside the mirror & near the sensor first.

    The sensor is the little black button sticking out underneath the mirror.

    Check the electrical plugs are clean & a tight fit.

    If possible try & borrow another sensor & try that, Scrapyard, Most mid 1990s onwards Peugeots, Citroens & Renaults have these fitted.
