Before someone dumps gear oil into their clutch packs,
235.63 = 75W80, GL-5 (thanks @veeeight for confirming) gear oil = goes into the center hypoid chamber
235.64 = 74W70 oil = Shell 0870 B; BMW DTF-1, or MB 000-989-440-611 = goes into the clutch packs on each side
@Theo, the spec 235.15 is 75W85 weight gear oil (unknown if GL-4 or GL-5, but would strongly suspect GL-5 for use with hypoid gears), according to MB's operating fluids website. The 235.63 spec of 75W80, GL-5 should perform very similarly to the 235.15 in a rear differential application. Just like you can run several weights and specs of engine oil without harm, the same is true for rear diffs (ex. running 75W140 in an application that calls for 75W90).
In the TWIN rear axle, I'd be much more concerned about getting the clutch pack oil spot-on than the hypoid chamber since the clutches need to slip at a predictable rate.

It all makes perfect sense @fatty45 and joining this forum was the next best thing after purchasing my A45s (although I joined here a few months before picking it up). Who knows how in the world I would've been able to deal with all that mess that AMG has been putting us through. I certainly wouldn't have known a thing about our vehicle's tuning difficulties, so I would have probably jumped straight into tuning it to 500hp without knowing anything about WOT duration and ambient temperature limitations that @Turbo Ed has explained so nicely, and I wouldn't have known about our spark plugs and differential oil shortages, to at least place an order in advance. And I'm far from acquiring AI capabilities, but we're fortunate to have one here.
The thing is, it's out of my hands. I can't seem to be able to find the .64, OEM or aftermarket, and if dealer can't get it for me then either I'm not changing the oil at all (which ain't happening), or .15 it is. I don't think I have another choice here...
Oh, you guys care to know what MB responded? I asked which is the correct oil for my car, 235.15 or .64 and I wanted them to answer (expecting them to point the .64) so I would show my dealer the screenshot. And their response was that I need to contact my dealer. Who has sold me the .15.
And the paranoia goes on...

What I'm planning to do next is show my dealer a few pages that I've printed, as per @veeeight advice:

They may question the third source but certainly can't say a thing about MB's own pages.
Other than that, dunno what else I can do really. Set up my own lab and produce a .64?

Oils sitting in @Turbo Ed's garage in close proximity to his $30k AUD in A45s upgrades, would instantly cost an extra 500%.

So I did... went to spare parts, I said any news on my orders, they said our system shows that you have the right oil , which is the 235.15. Two guys at the spare parts looking at me not saying a word while I was explaining that the .64 is the right oil for the twin clutch unit, as shown on the previous links, and especially those from MB themselves. Brought the printed pages with me and showed them. In the end all they replied was "so is the 235.64 the oil you want?" I said yes, and they said "we're ordering it for you". Frankly I don't give a flying **** if I have convinced them about the fact that the .15 is the wrong oil and that what this car needs is the .64, which they sure looked like they didn't care, the only thing I care is that they have ordered the .64. Other than that, it really is like talking to a brick wall.What I'm planning to do next is show my dealer a few pages that I've printed, as per @veeeight advice:

And let the wait begin... once more.
Then I asked about the spark plugs, they said order is still pending, unknown ETA. I said this whole thing is ridiculous, you guys are unable to service my vehicle. They said it's not our fault and that I should speak to the main distributor, gave me a number. I also found out that they are now under new administration as they were recently acquired by another company, which is never a good thing when you're talking support. But what they said next was what made my blood boil. They said MB will not express ship any parts, including the plugs, unless the vehicle is VOR. Otherwise the parts are on backorder. So I said "so you're expecting for parts to fail before you service them, is that what you're telling me?", more or less yes.
Going to call the distributor, see what kind of BULLSHIT they have to say. Parts need to fail before you service them, what in the actual ****??!!
Someone replied to a similar thread on another forum that A000-989-36-08-11 satisfies MB235.63 requirement. I asked for more details (source) but have not received a reply yet. Additionally, I searched (from US) for this part number and it shows "Transmission Oil" and costs $73 USD per liter! I have not been able to find any application info. Anyone know anything about this part number?

Guys,
OK I think we are all in agreement that obtaining the correct lubricants for our rear axle assemblies through the MB Network is problematic, at best.
So, I have been spending recent days talking to Magna, (who, incidentally, claim our assemblies were designed and are built in a different Magna facility to the VAG products, however who really knows, outside Magna) and then to various large European lubricant suppliers, on the basis my local Australian specialist lubricant supplier is of no use to most of you.
So, firstly the rear axle differential oil; MB reference 235.63 This should be GL-5 rated SAE spec 75W-80 oil, in my opinion a full synthetic. (Some companies claim to meet the spec with a partial synthetic). Many large European companies offer this oil as a full synthetic; however, the company with the widest distribution, literally across the world and therefore of the most use to all members here, is the German company FUCHS. So best to start there.
Then, the unique, (as far as I can tell) to our vehicles, the side clutch pack oil; MB reference 235.64.
According to Magna, this IS different to the VAG spec.
Both the oils apparently are only made by SHELL.
I cannot swear to this, given the number of specialty lubricant manufacturers in the world.
However, if we are talking a true muti national lubricant distribution system, so everyone here can use the info, I think SHELL is it.
Shades of the Spark Plug fiasco.
The VAG product supposedly uses SHELL's TF 0870
Our vehicles use SHELL's TF 0870 B
The difference apparently all being in the B.
Now, I am not saying your local SHELL distributor will have it on the shelf; however, they SHOULD be able to order it in for any of you.
Like I say, really reminds me of the Spark Plug scenario.
For a "mas produced" vehicle, our cars are unique in so many areas it is really quite extraordinary.
No wonder the typical MB Dealership Workshop / Parts Dept are completely out of their depth.

Yup.
Correlates well to what I posted in previous threads/posts.
M-B 235.64 is Shell TF 0870 B
You can have 209 litres of the stuff here

@Turbo Ed - I would have thought something from their Sintopoid Hypoid range would be more suitable?
Absolutely, my error, shall edit the post,

There is a Fuchs Titan Sintofluid 75W-80 which is GL-5 but is listed as manual transmission fluid. Note the name is Sintofluid, not Sintopoid. I assume that's NOT the one we want for cross reference 235.63?
Closest Sintopoid I have found (to meet 75W-80 as per MB sheet 235.63) is the Titan Sintopoid 75W-85, similar but not the one.
As for Shell TF 0870 B, that meets 235.64
www.kreissler24.de
it says out of stock
..and then I stumbled on this one here made by Febi:
listed as Transfer Case Oil and if you scroll down there is a table that says Specification TF 0870 B.
Any thoughts on that one?
Also how many liters do we need of 235.63? I know we need 0.8L of 235.64 (0.4L per side) so that's a 1L bottle.

Yup, just make sure you get the B for our cars.
@Theo , I was actually going to post on this last night my time, after my initial quick response to @veeeightThere is a Fuchs Titan Sintofluid 75W-80 which is GL-5 but is listed as manual transmission fluid.

You have discovered the issue which led to my original error.
Magna / MB have specified what appears to be a Grade, 75W-80, normally used as a gearbox oil, for the rear axle gears.
I suggest you talk to Fuchs Greek Distributor and see if they actually make a specified Hypoid gear oil in 75W-80.
They may not.
I believe @veeeight found a specialist UK manufacturer who did offer a GL-5 75W-80 hypoid axle gear oil.
Perhaps he would be good enough to re post it.
I shall also talk to Fuchs Distributor in Australia and see what they have to say on the subject.
Re the clutch plate oil, I would suggest you speak to Shell's Greek lubricant distributor and simply have them order it in for you.
Likely to take while, so sooner you do so, the better.
Febi, is quality German lubricant company, part of the Bilstein Group.
However, I wouldn't take the chance, unless absolutely backed into a corner.

I wonder on that basis, what Fuchs would say about their 75W-80.
Still trying to reach someone in Technical at Fuchs Australia.
Friends, I'm back . AMSOIL GL-5 75W-90,There are currently no issues.
OH,
GL-5 SAE 75W-90 is readily available from multiple sources.
The question is all about the specified, by both Magna and MB/AMG, GL-5 SAE 75W -80
