Transfer Box Issue

[crossbro]

Just had the transfer box replaced under warranty on our Macan 2.0 Petrol, just before the end of the 3 years.
I noticed a slight but discernable vibration through the steering wheel when setting off, particularly under extra load such as pulling away up hill. It felt like the car was going over small speed bumps. Initially as the tyre were well worn, I though this may be the problem, but after replacing the tyres the fault was still there.
OPC immediately diagnosed fault with Transfer Box and ordered a new one from Germany,and fitted week later.
On viewing other Macan forums it appears this is not an uncommon problem, and the OPC service manager confirmed there has been 'a few', but I think was reluctant to admit how many. Be interesting to know if other PCGB Macan owners had had same problem.
I recommend all Macan owners be vigilant to the symptoms whilst still under warranty.

I know of at least one member in my area who has suffered a similar problem. I believe it relates to water penetration through the unit's breather system and there is now a modification issued to resolve this.

This is exactly the same symptoms I have with mine. Just started doing this the last couple of weeks.

Mine is a 2016 Macan GTS. Will have to get it booked in.

Thanks for the warning.

Hi all im new to the club joined a few days ago. Just getting used to looking around forums etc. I have Macan 3.0 diesel s its nearly 3 years old in November. I had the same issue with clunking through gear change Porsche Tewkesbury confined Transfer Box was faulty. I had a road trip to Monaco booked & really wanted to take the Macan & stretch its legs!! Porsche Tewkesbury said it would be fine to drive it there & back (Still under warranty Road side assist etc)

Anyway flew down there & back no problems. it then went in for a new transfer box & fingers crossed all is well..

Hope to meet you all soon...Mark

I’ve been experiencing similar symptoms on my 2015 Macan diesel S with just over 30000 miles on the clock. This is my first Porsche BTW. I’ve owned it for just 5 months. When I pull away from a standstill on perfectly smooth tarmac it feels like I’m driving over small bumps also judder when reversing up any sort of incline. Is this an acknowledged problem by Porsche whereby they will replace the transfer box as a gesture of good will? My vehicle is now out of its standard warranty. I feel this is totally unacceptable on a car of this “quality” which has had just one service and is barely run in by my way of thinking. The car was originally supplied new from Porsche Center in Leeds and has had just one subsequent service by them. I’d like to have this issue dealt with an OPC dealer either Wilmslow, Bolton or Leeds. Is any one of these better than the other? Wilmslow would be nearest for me geographicall. Also did having a new box fitted cure the problem permanently? I’ve seen posts on other forums where people the same issue have had to have a second replacement box fitted. Any advice would be appreciated.

It may not be fully relevant but my 2013 Diesel Cayenne is experiencing the same problem and is going into our OPC for transfer box replacement tomorrow. My car has 110,000 miles on it and is otherwise in top shape. I too experienced the vibration through the steering six months ago and recently it has lurched from a stop or in 2nd to 3rd. Seems to me there is a known fault.

Do you think my 2015 Cayenne 3.6 Petrol could develop this fault ?

It has only done 12K miles ?

 

[manc2608]

During my investigations I’ve been told that Cayennes can suffer related problems too. I just wish mine had got Past the 110,000 mile mark!

Hi, well here we are again! Macan S diesel, 46873 miles now to be fitted with second transfer box! very disappointed to be told the first time it was due to a short vent pipe causing water contamination to the oil. Now the unit has been modified so all will be well!!?? Can I ask has anybody else had the same issues or do they just tip toe to the shops and back? I would really like to know??

Hi G7 tar

I had mine replaced back in June/July i have done approx 10,000.00 miles since in approx 7 months & no issues so far ...all fingers crossed ...but have had other problems as reported Not that impressed with my Porsche if im honest.

I had mine replaced just before Christmas under warranty.

2015 SD with circa 35,000 miles

Hi All

I sold my 2013 Cayenne Diesel there in January and it had 103K miles on it never had one problem with it.

I purchased a 2017 Cayenne S Diesel in January with 20k miles. I have done about 2k miles and guess what Transfer Case faulty. Its booked in

for next week in my OPC.

I really am disappointed. It looks like Porsche are on the slippery slope with regards Quality when you read of all the problems they are having

Transfer Cases, Gearbox issues, Engine failures etc etc.

I have owned Porsches both cars and SUV for some time now. By the way the Cayenne S i bought was the first second hand Porsche as there was nothing

new in the current Porsche range that suited me with regards to economy.

Maybe its time to consider another Manufacturer.

I feel your pain have wondered about an other manufacturer myself. We have had 7 BMWs in the household for 15 years before we got the Macan without any issues.

I love the Macan dearly but worry that I might need a second transfer box replacement. Last fix was 5k miles ago.

I would expect the transfer box box to be a ‘bought-in’ part also used on other vehicles but I have not heard of such issues. Alternative reason could be how/where it is fitted to vehicle.

Any automotive engineers have any insight?

Well was to get my Cayenne Transfer Box fitted last Wednesday but was cancelled due to my OPC not having the Vent Pipe . Still haven't heard

from them yet.

OPC are saying the problem is not the Transfer BOX but the Vent pipe , apparently it allows moisture into the Transfer Box

which causes it to fail.

So when replacing the Transfer Box the new vent pipe must be replaced.

I am assured by OPC that this solves the problem.

So why are they failing again .

People need to ask are the Modified Vent Pipes being replaced when the Transfer Cases are replaced.

Just had mine replaced on 65 plate diesel S but beware that the new case has an ECU which needs to be coded otherwise the car will only operate in 2 wheel drive. Not a problem with that and I have ordered a new S so it will be part exchanged.

Hello, I have a 2017 Macan S that just had a transfer case installed by a dealer in Chicago. I noticed a slight hesitation on first gear acceleration. The dealer is also replacing one of the drive shafts. The car only has 23000 miles on it so I was surprised that this happened to a supposedly bullet proof Porsche. I recommend all Macan owners to look for this problem.

Another transfer box casualty. My 2017 Cayenne S Diesel is currently getting a replacement under warranty. Just 3 years old and only 23k miles. Does anyone know if it's just a straightforward replacement with same or is there an improved item that solves the problem so it doesn't recur.

My Cayenne S Diesel had the transfer box replaced a couple of years ago, but it failed again after around 25,000 miles or so. It was replaced again earlier this year and I was told that the box is now a new design with completely new internals, and so the problem shouldn't re-occur - I will be maintaining the warranty just in case!
