996 turbo diff oil leak

[longbonce]

Looking for any info or advice,i'm working in the middle east and have noticed a wet patch under my car in the car park,i took it to the local dealer yesterday who in the past i've found to be lets say not that great,however theres not any options where i am for repairs.
They called me today to say there is an oil leak from the diff which cannot be repaired and that the car needs a new gearbox! I'm no expert but found that a bit extreme when the car has only done 37000 miles,the car is an auto and it goes up and down the gears with no problems and theres no funny noises.
The serviced manager i believe is an english guy whom i plan to go and see tomorrow rather than listen to a filipino service advisor who's taking advice from a filipino so called mechanic!
Has anyone encountered oil leaking from their diff?

I think what they are speaking of is the wheelset itself. The problem is that you cannot buy that part - we have been through that process already, including with our partners MKB. It just doesn't exist and we have access to both Porsche and Merc Benz (who make the box).

The only solution which is what we done before is to buy another gearbox and use that, or if you already have say an upgraded version, take the wheelset out of the purchased one and swop.

If the wheelset goes, it will give a very faint whine on pickup.

The diff(wheelset) is part of the tip box and has different oil in it. I would first drain the oil in the diff - if it is black and smells burnt, then it will not be good news.

If you can get your shop to provide me with the Tiptronic control unit faults codes, then I could diagnose better for you. There are a couple of seals that can be replaced as well near the diff.

If you can PM me some photos of the leak itself then that would help.
