Got my new transfer case installed today. Came directly from Germany last week. Part number 95B341010AX. Drives as smooth as a Lexus now ;-)

Got my new transfer case installed today. Came directly from Germany last week. Part number 95B341010AX. Drives as smooth as a Lexus now ;-)

One of the questions that I can't seem to find an answer was:

Those with transfer case replaced, do they actually solve the problem long term?

Even after replacing the transfer case, it did not show any marked improvement for @Finerthings.

My '18 Macan S was in production between 3/27/18 and 3/29/18 with about 3000 miles on the odo, and it is showing similar symptoms as she described.

Trying to characterize the symptoms more before taking it to the dealer.

The fundamental problem is the viscosity of the oil in the transfer case that made the clutch plates grabby. It was being highly affected by moisture from a poorly designed vent tube. This problem has now been solved, they claim. And in my case, the replacement is spectacular. Night and day. We'll see how it progresses.

What to do with our transfer cases that have not been replaced? Still waiting for the symptoms to come up here.

From the description of this I wouldn't be surprised if Porsche didn't recycle those transfer cases if all they need is new fluid and a better vent. How come they can't do that while it is on the car?

Definitely makes you wanna go out and DIY the transfer case fluid. Anyone done this ?

If it’s same as the differential fluid change, it’s a piece of cake.

Yes they do recycle them. If you look up the part number for some online vendors, you'll see there is a core charge that is refunded when you send them your old one. However, the changes are made to internal baffles for the vent as well, so it isn't something that would be done in the field. Porsche would want to do QA on every one they updated in the factory.

BTW, the factory that made these transfer cases is in Mexico. My transfer case has a Made in Mexico label on it, as are the ones I've seen on eBay.

They are called re-manufactured parts and are used all the time.

Warranty repairs can use either new or re-manufactured parts. I think it is stated somewhere in writing.

This is the first time I saw an explanation of the actual issue and the solution. Thanks you for this and it made me feel a little bit better. All this time, I wasn't sure whether they were just replacing transfer cases or actually solved the core issue.

Me also thinks I'm now running into the same issue.. bought my 2018 Macan S May 1st and now she has 3300 miles on it. I'd say the last 500 miles or so I've really noticed that even at 35-40 mpg on backroads it feels like its stuck between gears (not in sport mode) and at slower speeds seems all jerky. Was actually making a bit car sick there. So calling Porsche of Burlington Ma tomorrow. Something isn't right.

If this TC need occurs couldn't you go to the adjustment and turn off the rear wheel bias?

How would one do this out of curiosity? I don't see it anywhere in manual?

Go to the gauge to the right of the speedometer and page through the options. It is there. Keep hitting the button on the steering wheel and when you are close, scroll.

Turn off rear wheel bias..... in the MFD ?.. Are you sure ?

I couldn't fidn anything other than resetting all PCM settings. Checked the manual and also found nothing about this. I got an appt with dealer next week to check this low speed subtle "bucking" that I get between 2nd and 4th gear (<40mph). No where near as smooth as my other Audies or Benzos. So much for PDK being this glorious better than anything on earth system .. pfftt

If your priority is a smooth shifting transmission, dual clutch is generally not your best choice. On the other hand if your car is bucking, sounds like something is amiss with the transmission or something else.

Go to page 183 in your manual (mine is for a 2018). It is under torque split. Figure #134 shows the display.

I ran a warranty poll on UK forum, 5 replacements as of today (from 21 posts), not quite statistically relevant but 25% of all warranty claims from that small data set.

cant post the link as I am only a 3 poster here.... but its under the title "Warranty Claims Poll / Data" on macanforums.co.uk

No it does not

I'm sure that this question has already be asked but I can't seem to find the answer. Has this be resolved in My18 Macan or I could potentially have the same issue when my GTS arrive next month.
