    Hi all,
    This is on a 2012 3.0TDi S-Line Avant.
    Had a couple of 'false alarms' recently with the car telling me it's short of coolant, when it obviously wasn't. The first time it simply went away when I restarted the engine, the second time it persisted but went away after I waggled the wires on the sensor unit.
    So it's maybe a loose or dirty connection there. I couldn't make out if the sensor has a plug/socket arrangement, or if it's hard-wired in. Does anyone happen to know? If it's a plug I couldn't see how to get it out.

    Scratch the prongs on the reservoir with a flat screwdriver, see if it goes away.

    Thanks for responding. I guess you mean the prongs in the connector. Question is, how do you get the connector apart?

    You need either lift the tank up slightly or remove the tank to get to the connector underneath.
