    I had the same issue. It was the coolant pump. Sometimes when shutting the car off after a more "aggressive" drive , the pump will slightly leak due to the temp+pressure in cooling system. Then next drive there will be no leak because the pump is running and the coolant is flowing. I had my water pump and timing belt replaced under warranty at 95k, no more slow loss of coolant Currently at 101k.
    Hopefully this helps

    I'm going to bump this thread up. I've replaced my water pump, thermostat and reservoir cap and can't find this **** leak! I can smell the coolant when I get out of the car after a drive or if I'm sitting in traffic. Has anyone had any luck locating these leaks?

    Replaced those coolant lines going to the oil cooler a few weeks ago and also the oil cooler itself.

    STILL getting the smell of coolant!!!! This is so frustrating.

    Have you checked by the EGR valve? Maybe one of the gaskets is failing causing a leak.

    My 2015 had a similar very slow leak, just a hint of smell. Dealership never could find it, and it still has the UV dye added. After a while it appears to have stopped. Have not seen any further loss of coolant, nor smell.
