I was not aware the electronic diff had separate compartment for the clutches. So is that separately serviced with a special fluid? I will dig into the service manual later.
Yeah, I've never serviced it and I'm not aware of any particular interval to do so, but it is separate from the eLSD diff fluid. It may not need service unless a hydraulic line is disconnected letting air into the system? Not sure.

The eLSD clutch actuator system uses Dexron VI ATF (P/N: 88861037 in US, 19264717 in CA). Capacity is 0.160 liters or 5.4 oz. Looks like you need a specific tool -- DT-51381 -- eLSD Coupler Release Bleed Tool. I've attached the fill/bleed process from the service manual.
