At 250,000 on my 3.0d, my rear diff failed. I replaced it with an X5 M diff. Bare in mind it was tuned to almost 100hp more than what it was from the factory and used that power on a regular basis, so the fact it failed is understandable. Transmission is still working perfectly for the new owner at 300,000, just regular fluid and filter change / service... whereas on my 03 cayenne S, I had to have the whole gearbox re/built at 100,000...
The 100hp increase was achieved by a remap, bigger intercooler with stronger piping to handle the boost, and a turbo re-build.
