2018 GLA 250 4matic...transfer case fluid to swap or no?

Does the car have a transfer case that needs the fluid changed or no?
Hoping someone here knows a definitive answer.
I am seeing conflicting info online. If yes, what fluid is required? Is there something acceptable/comparable besides the genuine Mercedes fluid?

Thanks in advance!

Ron

Well, as per an FCP Euro tech support specialist, the answer is no....it's shared with the transmission fluid.
He researched it and really checked into this for me and that's his conclusion.
I'll still double check once I get the car in my lift to do the transmission service and the front and rear differential fluids, but I'm going to believe him.

The tech is correct. I don't have the WIS in front of me right now to pull pages for you.

But how did the job go?

Haven't had a chance to do it yet. Hopefully within the next week or 2.
