Clare oil

one more comment on oil loss - smoke generation.
I was in the workshop again today.gear and engine are tight.So no black
or red oil to see.The oil,which is now leaking out is colorless and smells slightly different,
it is diff. oil and is filled separately .at diff. are two screws ,one filler
and underneath one to drain.For some reason they have too much oil into the differential
tipped,so that it was pushed out somewhere.One suspects again by the Simmerring
I believe gear side.It could also be pushed out by the fittings on the diff
The excess oil was drained and now it is so to speak dry.
My concern is the sealing rings, which must have been widened by the increased oil pressure
I hope it's all ringing!
So far, thank you for your tips and reflections on my problem.
I performed it at Audi and they checked everything.It seems, I can hardly believe,
to be all right.
I think I'm going for another round, until then,
Frank
