Online log of Audi service bulletins?

[bungle]

Came across this (from the US), and relates to the 2010 S4's sports diff; how do I find out if there is an equivalent UK version? (would be strange if there wasn't?)

ahh the differential oil leak topic coming up again... its been discussed at lenghts here and on US forums and consensus is from what I gather that it wasn't a genuine problem affecting many cars and possibly just a one off.

Oh I see, not noticed it (only had S4 a few months).

Seems strange that there would be a service bulletin addressing such a small issue then? Can't imagine it would in any way be a bigger issue in the US than here.
