Rear Diff Oil for 4 motion

[gelly]

Hi All,

I have a slight leak on one drive shaft from my rear diff on my 2004 1.9TDI 4 Motion.

I need to fix the leak - hopefully just the oil seal, and fairly straightforward I hope.

The question I have is what oil goes in the rear diff and quantity required please?

If anyone can share any info on this or the process, it would be appreciated.

Many Thanks
