A good result.

 

I don't think water intrusion is a factor in the Macans Transfer Case issues, I think that was the problem with the Cayenne Transfer Case, which is a totally different design. The vent tube on the Cayenne was changed by Porsche, but the vent on the Macan Transfer Case was never changed.

 

I had the TC on my wife's 18 Macan GTS replaced under warranty with p/n 95B341010LX in Feb 2023. Now she is experiencing low speed stuttering again unfortunately. Looks like this is the latest updated reman p/n but when checking online it looks like LX was replaced by PX. Taking it back to the dealer to check it out. They also did the timing chain cover bolts under my Fidelity warranty but I can still smell oil and my Indy said there was oil all over the front of the engine.

 

Keep us informed please on the TC

 

5 years old Macan Turbo, has been great until last year. Oil leak and lots of engine camshaft errors.

Finally Porsche dealership fixed the two issues above, had the infamous cracked bolts and timing chain oil leak, and they replaced a bunch of selnoid valves. Big job.

After this car stopped giving the engine check light for the camshaft errors, but started being very rough, jerky, and makes lots of noises when driven at very slow speeds after a stop sign for example. Problem mainly happens when car is cold or first 30 mins of use.

Took it again to Porsche and they could not replicate the problem. Told me give it time the car computers need to relearn things after that major job. I’m not so sure.
They told me they don’t think it’s the other common problem of Transfer Case. Seems reasonable from wha to read about it.

Video shows the jerkiness and loud bangs (2 of them each has 2 bangs) around second 5. Each bang comes with a jolt in the car forward.

Any help or suggestions welcomed! Thank you!

 

 

Previous owner of the 2016 Turbo. This sure are symptoms of the Transfer Case.
There is a simple procedure of how to determine if that is the issue by going into the OFF ROAD mode and turning your wheel sharply to one side and then the other when going forward then backwards. If you feel like you are going over rocks that is the expected behavior but if it jolts and makes lots of thumps and sounds, then you got a Transfer Case problem and it has to be replaced. There should be tons of info on the forum related to the Transfer Case. Ours was replaced at 30K miles as we could not stand the jolts and thumps at low speeds speed up or slow down. The computers need to learn excuse is nonsense.

 

Thanks for sharing!

The challenge is that the problem does not happen when I did the Off Road test you mention. What I am seeing now is becoming more clear. And I think you are right it's the TC! I think.

The problem is intermitted, but when it happens it feels like the car is about to halt. Almost like someone applied manual hand break on the rear wheels, usually happens on slow speeds on 1st or 2nd gears. Very consistent with the Transfer Care situation, basically the clutches inside the TC are locking, or something like that. Oh and I have around 26K miles and 5 years on the car, again consistent with when the TC gives up. I am surprised Porsche is not more willing to just replace it at this point.

So far the dealership is saying they want to reproduce it, but they could not. I am getting frustrated a bit and when the problem occurs, it seems there is so much tension on the engine and transmission that I am now worried this problem will cause more problems later.

I have extended warranty and also Porsche has a special 7 years warrantee on the TC. I am going to try to get them to pay for a replacement at this point, will see how it goes. They have been very good so far to be honest, really like their service.

 

I don't think it would hurt anything to leave it disconnected, then you have a 100% rear drive Macan.

 

Did this with dealer for a test once. You will get an AWD fault , obviously.

 

Is there anyway to kill the fault code?

 

No

 

Well I'm 2 weeks away from my 7 year extension ending so I did the test. 2017 S 126k miles, unknown history on the transfer case but the car lived entirely in Socal doing long highway drives.

With Off Road mode on, Low speed tight forward turns no problems. Reverse however I do feel some mild to medium thumping at sharp steering angles. Made an appointment with the local dealer and hopefully can squeeze this replacement in.

 

Medium thumping in Off Road mode....in Reverse gear.....almost full lock turn...is normal my dealer says. Anyone?
Should this be smooth ??

 

Ooof I hope my dealer doesn't say that and slap with a $200 diagnosis fee.

 

Any updates? I'm about to try the same at my local dealer 😓

 

I hope they diagnoses as bad TC case. As I will march back to my dealer

 

Quick update: so far the problem seems to happen more often after reversing, especially with sharp left or right reverse. No issue when reversing, but happens right after the reverse.

Dealership is still trying to reproduce it.

I am impressed with how good the dealership and Porsche USA are so far, really trying hard to fix the issue.

 

Try asking for a ride along so you can reproduce it for them.

 

Thanks for the suggestion!

I did a bunch of these but they were all negative. The problem happens like 2 times a week, very bad when it happens. Now that I know reversing triggers it, hopefully I can go again and try to repro with them. Thanks for the suggestion again.

When you say reversing triggers it , do you mean you experience the problem in normal drive mode mode , after reversing , and only in Ofd Road mode ??

 

After and not during reversing.


I reverse out of parking spot, car is kinda cold, turn left and right and then drive forward. Only then it kicks in.

 

Not a reply, but, can anyone confirm the cost for a replacement TC?
I have a 17 GTS with 77,000 and my SA tells me the TC has not been replaced. The car drives just fine, but, What to do next? am I going to have the problem eventually or did some escape whatever failure created the problem? this is a bitch...

 

If the car is driving fine don’t replace the TC but do replace your dealer.

 

Well showed the tech the thumping in sharp reverse in off-road mode. They told me they can’t do the warranty work based on that because he says the car expects off road terrain, not tarmac.

 

Do you have another Porsche dealer close by? You can always get a second opinion.

 

Just tried off-road on gravel… tech might have a point. I don’t feel anything other than the rocks when doing the sharp reverse turns on loose ground.

 

try it on flat level pavement....same ?

 

On pavement it thumps, on loose ground it doesn’t. The explanation seems to be with grippy new summer tires, the off road system is expecting no grip but there’s too much grip and that’s why it’s thumping.

tech says Porsche will only approve warranty if the thumping occurs in regular mode.

 

So this is the A variant of the transfer case? I know the replacement refurbs end in X.

Car has 126k miles on it and it seems really new?
