What were you all able to find on the coolant? I'm working on a Tesla LDU from a 2014 Mercedes B-Class Electric Drive. Looking in the operator manual, it makes reference to 310.1 which can be found here:
https://operatingfluids.mercedes-benz.c ... t/310.1/en
This subsequently references 320.1 for the coolant specifications. When looking at 320.1 is seems to say that all electric drive cars not in the Smart line of vehicles fall under specs 325.6 and 326.6. See 320.1 here:
https://operatingfluids.mercedes-benz.c ... coolant/en
It has a note, #2, stating "Restriction: Notes: For all vehicles with manufacturing date as from May 2014"
Both 325.6 and 326.6 list Zerex G40 as one of the many options. The issue here for me is that G40 is pink, and while the label states it is for Mercedes, it seems like G48 is more along the lines of what is in my car, and all of the RAV4-EVs and Tesla's I've seen taken apart. Blue-green color, and it says Mercedes & Tesla on the label.
Noteworthy is the fact that 325.0 and 326.0 specs from the following link specify G48:

Here is the bottle I picked up:
Any thoughts on this appreciated.
