We have started to see several of these recently , this is a 2012 model .

Kinda figured we might as well have a look inside and see what's going on and i'm sure there will be someone on the forum that likes to see things in bits Very Happy

Various images of it apart and then partially stripped.

New clutch pack , in depth cleaning of parts then a forced regen to recalibrate the control unit / motor seems to have fixed this one .


Right click any image and select view in new tab ( chrome ) for a larger picture .

Interesting post Iain, thanks for the pictures and it is good to hear that you can repair these rather than replace!

What was the mileage of that vehicle and the condition of the transfer fluid which you drained?

2011 Porsche 997 Turbo S

This is quite a common failure .....Mine was changed at 30000 on my 2015 958......
I was told it’s a design fault of a badly routed breather pipe which allows water ingress in certain conditions ...
Mine was carried out under warranty but if not it’s a 4.5k job if it’s an OPC replacement....worrying costs but a good reason to keep the warranty going ...it may not be the only time it gets changed ...
I suspect it’s also due to uneven wear on tyres back to front re the rolling circumferences and the transfer box is the unit that synchronises the front / rear drive split ?

I’m prepared to see mine changed again ..

There are stories of vehicles in the US of A having 4 or 5 changes in the life of a Vehicle!

Frightening on a Porsche .....

This car had done approx 60K miles ..

It had a modified breather which was a problem on cars without this .. water ingress and oil don't mix well .

Circa £1500 - £2K for the above .. diagnosis of this fault isn't easy .. it feels similar to an engine running fault .

This seems to be more of a fault on the later cayennes than the earlier ones .

Incorrect tyres will have a significant impact on damage to diff / transfer box on a cayenne than a sports car ... no transfer box but you get what i mean .

N rated tyres .. must be the same per axle .

Oil was no where near due a change and was fine .
