Also did the front diff of this 2015 C300 4matic with 105k miles. Drain plug is right there on the passenger side - can't miss it - 6mm hex. WIS says capacity is 0.55L I only got out 0.43L and it was really dark. EPC does not show any vent and visually I don't see anything up thereso pushing will be the only way to fill it. I decided to push in 0.55 knowing that I would lose maybe 0.03 or so before getting the plug back in. What I don't know is - is it now slightly overfilled or did we lose about 100mL over that 105K miles...?



To push it in, I used a CTA 7415 (fcpeuro), this is the same adapter to push in the transmission ATF. The front diff and the trans use the same plug. I removed the adapter tubing from my trans setup and just taped it to the cheepo hand pump - worked great.




Don't forget to use a new copper ring, its the same one for the trans - A007603012102. Torque on the plug is 20NM.
