I have 59k on my macan and am doing this plus the transmission gear oil and rear diff oil. I had the clutch oil already done by the dealer. I ordered the parts to do this and the quantities the dealer verified was :

transmission gear oil 4.1
transfer case 0.58
rear diff 1.2

I usually get the workshop manual instructions from the tech info piwis site but seems to be saying “billing provider down” so I can’t get the 1hr subscription to get the docs.

Also when I crawled under my macan to check the drain plugs I saw a slight seepage between the tc and the trans output so I’ll be changing the bushings/shaft seals there as well. Definaitly a good thing to check, if I had not check to do the fluid change I would not have noticed the slight leak and with such a small quantity of fluid in the tc a slight leak could mean total failure.

Any chance you can post photos of the location of the tc, with other components in the photo for reference points and arrow showing the tc fill and drain plugs?

I changed my oil this weekend and looked for the tc, but could only identify the PDK plugs. I want to diy the tc fluid, too. Crossing 75K miles . . .

 

Thanks Roop.
.58 Gal is 2.2 litres so we are close on that one for TC fluid.

The TC drain plug ....is it magnetic ?
We need a p/n for the plug.

Roop,
Is this the “seepage” you saw ?
To the right of the drain plug at the seem if you will.

You don't really need to change the rear differential fluid at 60k miles.

 

Coming from the tranny/transfer case joint. You may think it’s early for diff oil change but my brother had his diff fail in a different car at this many miles so I am doing it as preventative maintenance. The gear oil in the tranny says it’s lifetime fluid as well but look up the the dl501 transmission failures and people have had issues and attributed it to the gear oil not being changed. If you search transfer case issues on other forums for cayenne’s or other p cars some dealers are recommending 20k intervals for transfer case! It is .58l for the tc fluid and bonus, I got the instructions as well.

 

instructions

here are the service instructions from the workshop manual.

 

correct instructions.

found out those instructions were for the front diff/trans gear oil, here are the correct ones.

Roop,
Thanks for this , great contribution!

What is your second picture of ? Looks like a cover ?
Glad to see your TC drain valve is in as bad a shape as mine ! Lol

If your vehicle is still under warranty or you have an extended warranty, it might be a good idea to have the dealer do it. I say this because of the issues reported with many Macan transfer cases (including myself). Even out of warranty at least you can say that you serviced it at your Porsche dealership and possibly might be able to have Porsche cough up part of the money in the event that it fails in the future. Either way its a good idea to do it.

 

thats the cover underneath the tc. I'm changing the oil with approved porsche oil and I have no warranty.

 

No cover underneath mine that I saw.
We dropped the oil cover to gain access to it..... it was not metal.

Am I missing a cover ? That would explain the massive corrosion on the bolt!

I have 2 covers

 

Are you in North America Roop ?
This is odd.......

yes

 

Thanks for that link Roop !

check http://www.porsche.com/all/media/pdf/originalparts/en/KAT044_RDW_GB_Macan-1.pdf

this shows drawing plugs etc, all parts in detail

thanks,

I'm assuming the front of the car is to the left in the drawings?

 

Roop,
Are they saying here that only 500ml will drain out ?
Why would dealer say this takes 3 L ??


2016 Macan Turbo

 

That is exactly what they are saying, don't know why the dealer told you 3L. The capacity of the transfer case is only .58 L. You may want to ask them.

 

Have been reviewing the information given on this topic and am in hopes that someone more knowledgeable can help. With regard to the rear diff, 1.2 l of CASTROL SAF-PD, p/n 000 043 205 30 is the prescribed gear oil for a non-locker unit. The code I1Y0 applies. For a locking diff, 1.45 l of CASTROL SAF Carbon Mod., p/n 000 043 300 37 should be used. Code I1Y1 applies. How can we ascertain whether we have a locking diff or a non-locking?
p.s.: Just researched the answer to my own question. PTV+ (Porsche Torque Vectoring Plus) includes an electronically activated locking differential. If you have this option, be aware that the gear oil and quantity are different.

 

There is a part number on the diff as well.

 

This is a TRANSFER CASE thread.
Unless they the same fluids, start another thread so we do not have confused product..

 

Got it started

 

Cardan shaft out. Cannot bend more than 10 degrees when removing.

 

Man you pulling it all apart. What is all this stuff ? LOL
What have you done so far Roop ?


2016 Macan Turbo

 

Yeap, replacing the seals between the pdk and transfer case, that’s what the slight leak was - the seal in the transfer case. Will be doing the oil change and seal replacement tomorrow. Also putting in a diff vent kit for this and the diff to avoid the water getting in the transfer case issue. So far I’ve yanked the cross braces, heat shielding, exhaust, Cardan shaft and now the transfer case.

 

AMAZING Roop......so that little black “nub” you are squeezing is the infamous vent that causes all these premature failures, thats the first look I have had, thank you ! For posting.

Are you “modding” the TC with this ARB kit.......or just the diff ?

Can one access that TC vent without taking TC off car ? Looks like it. Thinking of checking mine.....it would be top side I assume ?



2016 Macan Turbo

 

Yea that’s the vent. Diff has the same one.the ARB kit has 4 ports to allow hooking up up to 4 assemblies. I will be hooking up the diff and the transfer case. The vent is accessible from under the car, it’s on the top of the t.c.

 

Cool, that ARB kit is news to me. Is that used mostly for 4x4’s that are submersed ?
How will you connect the .8mm lines to the TC ?
Is the ARB passive or need power?
Thx


2016 Macan Turbo

 

Yea it’s for waterproofing any running gear. It’s just a vent no power needed. I got some brass fittings and 1/2” id hose. Here’s a pic of how much fluid came out as well. Does not look like that is 500ml. Also see pic of transmission seal - that’s what’s was leaking. There are 3 seals in total, I replaced all of them and used Porsche radial seal grease to fill them up. Also put Porsche extreme pressure grease on the output shafts.
