It got cold this week and i noticed the binding at full turn, probably cv joints as u suggested. Not sure about the wheel spin issue. What tires are u running and are u getting the traction icon on the pcm? This sounds a little different than transfer case symptoms reported previously on the forum.

.....The first is when I'm backing up and turning very sharply. To me it feels like a bad CV joint as I think I'm feeling some binding through the steering wheel, and at the same time there is a loud clunk that would be noticeable to anyone . It does it a couple of times weekly, and seems to do it only when the drivetrain is cold. It's not new, and does not seem to be getting worse with time.....

One possibility not related to the transfer case is the Akermann steering effect. It is most commonly felt on all-wheel drive cars at low speed with the steering at full lock, cold tires, and when the road surface is damp, wet, or dirty . It's often more noticeable when the tires are wide. At full lock, the front two tires are pointed at slightly different angles, which can cause the tires to shuffle sideways during low speed parking maneuvers. It can be heard as a growl, a skip, a judder, or a clunk. I've not heard it on the Macan, but my Audi has does this when the pavement is wet.

Not sure what to think of your second set of symptoms. Although I've noticed that when pulling a very tight U-turn with moderate acceleration, one of the rear tires will bounce and skip if I'm too aggressive on the throttle.

My issues (shuddering, etc) began at about 6800 miles, I took it in on Tuesday at 8:00am with 7200 miles on it and got it back Wednesday at 4:00pm with a new transfer case. They also replaced the "park assist control module" and finally my diamond key will select and display the surround view , thanks to everyone who mentioned this was a requirement for early build (APR-JUN 16) 2017 GTS models.

I did not notice the traction icon. I have the Conti 21 inch OEM summers that came on the car, and a week ago I had my Pirelli Winter Scorpions installed. The second symptom seems to be the same regardless of running summer or winter tires.

I did not know that it's called the Akermann steering effect, but I believe what you were referring to is what a lot of Mercedes GLC owners are complaining about. It did cross my mind that might be what I'm experiencing, except I don't think any other forum members have ever had the same complaint.

Hey everyone,

I am about to purchase a used Turbo with 53k miles on it. I've been reading about this transfer case issue and I'm a bit concerned as I am buying a macan out of warranty. I have a few questions that I hope can get answered:

- Is this an issue that only manifests itself early on? From the research I've seen it only happens at lower miles.
- How can I find out of the transfer case has been replaced?
- How much would the repair cost out of warranty?

Thanks

@ozziegt, I am having this issue right now on 2016 Turbo (built in June of 2015) and had it since day 1. You can lookup up the most recent post "Clacking sound.." where OP is having it on the brand new Turbo as well. Our 14 Base Cayenne is in for transfer case replacement and the SA told me that they would honor any transfer case on the Cayenne even if it is out of warranty but it is a known almost 100% failure rate. The Macan does not seem to be so clear so you may want to consult your dealer before you buy it since risk on 2015 especially very high.

I spent over an hour doing some research here and on other forums, and it seems that higher mileage "failures" can be resolved just by changing the transfer case fluid...but for some reason the dealers are still opting to just replace the whole transfer case. I'll talk to the dealer and see what they say, but I am not terribly worried at this point.

Call a Porsche dealer with the VIN number and they can tell you if the Transfer Case has been replaced. Mine was replaced at 12,000 miles. Start driving your car slow and if you feel a slight vibration like going over small speed bumps. Beware! Also back up and turn steering wheel sharp while backing up and you hear like a grinding noise-beware.

 

[Stoofpilot]

Repair cost? Expensive. I wouldn’t buy it unless it was from a Porsche dealer with extended warranty.

I’ve read through all of the threads I can find on this. I first started searching the forums after noticing a very slight thump like a speed bump when taking off from a stop at around 10mph. This started happening just after 2 years of ownership, and was very subtle and intermittent, but definitely something I’d never felt before.

In another thread regarding lack of torque there was a post talking about the pdk remaining in 2nd gear when coming to a stop (when in Normal mode - e.g. not Sport mode) and then immediately taking off again. If you waited for a second or two it would shift down to first gear. I’ve noticed the times I have been able to reproduce it, is when driving in normal mode and starting off in 2nd gear. I have a number of 4-way stops in my neighborhood, where this happens. If I make sure it shifts down to first gear I have not experienced the thump. Also driving in Sport mode, it is more aggressive when down shifting to first, so even with a “rolling stop” as I normally drive I do not experience the thump.

I have not experienced all of the other symptoms that other posters have described, like the shuddering or grinding in reverse, and it seems to only happen for me when the car is cold, where others have mentioned it needs to be warmed up.

I only started noticing this because I was so used to the silky smooth acceleration. I had mentioned it to the dealer when in for 30K service, and they found nothing wrong, but also told me they had never had any transfer case issues with the Macans, just Cayenes. Now the thump has become more pronounced, when driving in normal mode, but still doesn’t happen all the time.

Anyway thought I’d post my experience with the sport vs. normal mode in case others are experiencing just the thump for now.

For those that do/did have transfer case issues does this sound like the beginning of an issue? Definitely would be great if it’s not a TC problem, but must say it’s in the back of my mind with about 1 year left on warranty.

Thanks in advance.

You may also want to do a search of "midpipe exhaust clamp" since others have confused similar symptoms with a transfer case issue.

Thanks I had read those but just had another look. I’m not having a shudder issue just the speed bump or clutch slip feel. Guess I’ll need to monitor until it gets bad enough and/or develops the other symptoms.

Had my Transfer case fluid change and dealer also had XL3 friction modifier and works like new

There is a big thread talking about this issue. I have a 2015 Macan with 36k miles and my transfer case was replaced last month at around 35k miles. My car was out of warranty but my dealer replaced the transfer case at no cost. My SA said the number of transfer cased having issues was high enough for Porsche to recall it but since it is not a safety issue they prefer to replace when it fails and that is probably why they are not charging for it. I asked my SA how much would be to pay our of my pocket and he said around $3.5k.

 

[jzwu]

Good news! My 2015 S has about 36k miles now and is out of warranty.

Guess when the TC fails I just go to dealer and get a new one for free.

 

[///Bruce]

ozziegt is on the right path. There was some research done on the Cayenne a few years ago. They too were having TC issues. What was found is you can dodge this problem by changing the TC fluid every 30,000 miles. This seems to work. I believe this is now recommended by Porsche for the Cayenne. I think this is a true statement....

What did they charge you and do you know how much friction modifier they put in?

What is friction modifier....and Porsche did this ?
