Clicking from Differential
Mostly when cold, tight slow turns forward or reverse seems to induce some clicking and juddering noises in the eLSD. Has anyone else noticed this?
I recently also changed my diff fluid to GL5 Redline 75w140 which RL says is the correct fluid for this car.

MB recommend that the rear differential fluid no longer neededs to be changed after the initial break in brake in period at 1,800 miles. I wanted to get it changed anyway in the near future but concerned it may not be done properly even at the Dealership thus opening a can of worns that I do not have.
Posed your issues with AI and photos below gives some recommendations. Hope it helps.

Yeah, I got the same results from AI more or less.
I think I'm going to try Castrol Transmax Limited Slip LL 75W-140 since it's actually recommended for MB 235.61.
It's also a GL-5 oil but maybe its more compatible.
