Try sticking modelling clay into the hex net. Then take it out and take the clay model to the tool store to compare sizes.

14mm

14 mm internal hex on W211.

Not sure about w210.

Also, be sure to remove the FILL PLUG first, then the DRAIN PLUG. This applies to any vehicle. Diff drain plugs can be "stuck" and will strip out. At least if you have a stuck fill plug you can still drive the car if you discover it BEFORE draining the oil.

Let us know where you find it. Most stores only have up to 10mm, you can rule out Autozone, etc.
