2015 GLA 250 with active from drivers side coolant leak.
We have 2015 gla250 which has developed an active coolant leak at the front drivers side. Can this be the auxiliary coolant pump ? It seems that the leak is right under the air filter box and drips to the splash guard. I have attached a video below.
thank you for your input.
