Went out this morning to top up diff until seals arrive, also looking closer to see which seals had failed.
Very hard due to amount of oil everywhere, fuel tank to rear was soaked.

The next part caught me totally by surprise.
Given the amount of oil everywhere I was thinking how lucky not to damage the differential permanently (especially after yesterdays road trip which couldn't be postponed).
Armed with a bottle of EP90 I started to remove the fill plug, Bosch (or words to that effect) oil gushes out, maybe half to one litre, hard to tell.
The diff only holds 1.1 litres so what's happened here, it was filled with new oil using the same ramps last year, topped off until overflowed then plug re-fitted - in theory it should be impossible to overfill?

My thoughts turned to an earlier post regarding the vent, it's tricky to access unless I can go in through the top (remove carpet and bungs if fitted?)
The car is cool having sat overnight, it didn't splurt out as if under pressure more as though just overfilled.
Cheers
