    Hi the water under the car might be from the air con. The header tank flow will not take place until engine is at normal operating temp. make sure the cap is on correctly I had this and the cap was lose. The water pump is in timing gear housing if it leakes it will put water in the sump no on the floor. Also it takes a long time for the car to get warm, for the heaters to get hot it usually take 15 mins of normal driving or 1/2 on tickover.

    I would change the thermostate first. That the cheapest option that will stop flow. A waterpump is about £170 and you have to remove the cambelt cover remove timing gears and then take the front cover of the engine to get to the waterpump. if you do that I would change the timing belt and rollers at the same time. I have never heard of waterpump failure on a V6cdti I have 2 of them.

    Do my dip and taste test to confirm whether it is fresh water or coolant
    As above, if you have been running the car with the air conditioning off, then as you park the car fresh water can continue to be expelled for some time and make it look like a leak
    Simply dipping your finger in and then tasting it will confirm which it is

    Equally, if the coolant system has failed the coolant level will be all over the place
    On starting the engine the coolant level should fall, resulting in the warning message appearing
    Once the engine has warmed this message should disappear
    On switching the engine off you should then be able to hear gurgling noises from the coolant bottle and possibly even see it boiling
    If that is the case, then I have a test for that, but perform the dip and taste first
