Hey, just bought a Mercedes Benz C220 Cdi 2013 Coupe and got a warning to top up my coolant. Is this a good amount of coolant, or might it be a possible leak? I have not found any marks on the ground nor any signs in the engine bay that it might be leaking, and the error has not popped up again after shutting the car off and on again. Got the warning a couple of days ago. Also, does the coolant look discolored? Might be old or it might be mixing with some oil, but i doubt it.
Thank you for any help!
