Interesting. Thanks for the additional info. I wonder why they made the change. Maybe just for the magnet.

Does the magnet plug for in the older cases ?

Does the magnet plug for in the older cases ?

Switching to a magnetic plug without changing the body of the transfer case would be a relatively low cost way for Porsche to reduce the amount of metal particles recirculating between gears.

But, I don't know if it works for sure on older cases.

The newer plug (with the magnet) is tapered, like the original non-magnet version.

Awesomne, so this would fit in a TX case that was part of the recall.....back in 2017 ?

 

[VAGfan]

I think so.

I was under my 2016 Turbo today for an oil change and noticed that my transfer case drain plug is the new style. My TC was replaced under CPO in 2019. Guess I need to find the updated plug before I change the fluid, just in case.

 

[Teddis]

My original 2016 case was replaced as well with an AX version.
Will the magnetic style plug fit ?

Hi All Macan Lovers !

I had same issue with my TC car was shaking like crazy in reverse and low speed !

Changed with the Ravenol DTF1 which I personally think is better than the Porsche transfer case oil, as it comes with some anti foam/moist formula, as we all know that these TC getting water inside so I would recommend it. Did 1000 miles with no issues !

Special thanks to @ttmacan for the instructions you just saved me from 5k€ replacement job 👍

Cheers all

Thank you for this detailed description!

I wanted to change mine early to remove break-in / wear materials, about 12k miles.

My 23S has a few differences from most of the photos and videos of the transfer case: It has a magnetic drain bolt (with a white sealant) instead of a hex plug, and a metal shield between the transfer case and exhaust pipes. It's bolted to the transfer case with two triple square bolts (M13 I think).

I can drain the transfer case through the bottom drain bolt with the shield/cover in place, but it blocks the side fill plug. I decided to leave it on and partially drain and fill a few times while starting the car in between each drain/fill to see if that would mix the old and new fluid.

Initial drain from the bottom was ~325mL. Fluid was nearly black and the bolt had some black metal paste on it. I added 325mL through the top vent (used Red Line MT-LV) using the same syringe from Amazon - thank you again!

I drained a total of 3 times and by that time the fluid coming out looked close enough to the new fluid. My simple math calcs show, assuming 500mL total inside and 325mL drains and 100% mixing of old and new fluid, 35% of old fluid remains after initial drain, 12% after the 2nd, and 4% after the 3rd. One more drain/fill would have been <2% old fluid.

Runs smooth, can't tell the difference in before/after.

P/N for the magnetic drain bolt: 95B301115

About to do this myself on my 2020 S and I imagine the second gen has this new heat shield?

Did it look very difficult to remove?

Can you reuse the magnetic drain plug or do you have to use an ew one?

Just a clarification: The Macan Transfer Case does not have a water ingress issue, the Cayenne Transfer Case has this issue. The Macan Transfer Case is a completely different design that what is used on the Cayenne/Touareg/Q7.

Great, hopefully the sealant doesn't need to be applied again.

 

[VAGfan]

Do not overtighten the drain plug (to avoid cracking the transfer case).
Finger tight and then one quarter turn clockwise.

Did my transfer case fluid today along with other things. It was pretty tricky filling via the vent hole with the syringe recommended by @Santirx . I feel like the right size clear vinyl tubing could make a nice seal on the vent hole and make filling easier. About 450mL + spillage came out and was pretty dark. Refilled with 500mL. Was super careful not to overtighten the plugs! The magnetic plug was reused with Permatex high temp thread sealant (this was kind of messy, so I'd use regular teflon tape next time).

Oh yeah, which scan tools can reset the TC oil wear indicator? FWIW I think mine was at 56kWh with 45k miles. No issues as far as I could tell. This unit was a replacement under CPO in 2019.

Congrats @drawz…

Did you use this type syringe?

This syringe makes the change easier.

Also, you don’t want the tubing to make a seal against the TC vent. You need to have space for air to come out as the TC is sealed. Otherwise the tubing will shoot out and spill oil all over the place.

I used the 500mL version of that. Good point about sealing. Maybe just something longer and more flexible then. Or sharpes like the tool in the service manual.

Appreciate your video on this. It was essential and gave me the confidence to try it.
