    On the W205 it has 2 coolant reservoirs which one should you top the coolant up from.

    The manual says the one at front left is the one to top up, the only thing I can see on the top right is the screen wash reservoir.

    That's a pickle! I would still say the one on the left (black one) as that's the one indicated in the manual, I haven't notice on mine if there are 2 reservoirs.

    Hopefully someone with more knowledge will respond with a better answer.

    There is 2, yes. The one on the drivers side (uk spec) is the main one for your typical cooling system like engine, radiator etc.
    The smaller one on the passenger side is for the charge cooler.
