2020 GLE 450 transmission, differentials, transfer case fluid?
Hello,
I need someone to confirm what are the correct oils and quantities for my 2020 GLE 450 VIN 4JGFB5KEXLA169883 ( 95k km )as I'm facing some issues (whining noise while steering on low speeds and accelaration on corners) after rear differential/transfer case oil change.
The noise existed before as well but it was really quite at first.
Interesting fact is that the issue reproduces only after the car is once well warmed up. No noise on cold oils ...
This is what was recently inserted into my car :
Engine - MB 229.52
9G tronic automatic transmission - MB 236.17
rear/front differential - MB 239.71/239.72 capacity ? transfer case -239.41
I just want to ensure the oils are the correct ones.
All oils were replaced back in November . Noise became more loud . That's why i did it once again and replaced it this week. The oil was not clean only after 10 k km but i didn't saw any particles in it... Just the color was darken.
Currently the noise is way better and not so aggressive like it was before. So the fresh oil works better it seems.
Heard about a secret (internal use only) mercedes genuine friction additive ? Is it worth it to try finding it and add it into the rear diff ?
Thanks for your support !
Cheers !

I'm doing this same work on Monday with my indie. I also asked Gemini AI and he wanted to compare his references to my Gemini AI output. I'll keep you posted. I have a 2020 GLE 580.
Some of the sheets list brands and blends (engine oil), some do not (brake fluid), and some provide very few. Many of the oil brand websites provide MB sheet compliance for their fluids. Every MB chassis seems to have its own set of sheets. As difficult as it is to assemble a list of brands and blends for each application in each chassis, the online suppliers' directories are frequently incomplete and in error, even when checking the compatibility of MB OEM fluid p/n's. As confusing as MB's fluids are, BMW hasn't even a fluids website and constantly changes which fluids are suitable for which vehicles. Even dealers are confused.

I wonder if the whining sound is a CV joint problem.

i was also wondering the same… Car was inspected in two Mercedes Benz specialized maintenance shops and from both places they told me all looks in good condition and they suspect the rear differential.
it’s a fact that after the second oil change on the rear difderential the whining noise is lower .
I assume we’re talking about low quantity of oil, bad oil, bad/heating differential or something like that.
Issue is only once the car is hot and oil respectively is also really hot and lubrication effect get worse because of the high temperature. That’s my observation but i’m not a mechanic.
Thanks for all the replies here ! If i find something else will let you know guys !
Regards,
