Today during oil change procedure I noticed a small sweating marks on both sides under the turbo area...
It is wet, but looks old or long time there / nothing fresh - maybe the sweating is very small but is..
Is this something I should be worried?
Any job to do or can live with it?
What is causing this?
Maybe this will help
I had the same problem (+heat shield slightly greasy) and during the inspection at Bentley they had identified a leak (and therefore replacement of seals) on the turbo oil return line.
The seal reference is: 078145757 - cheap part, but you'll have to dismantle the stabilizer-bar support cross-member - 3 hours of labor ( Bentley)
It's not major in absolute terms, but there's always the risk that, in time, the oil will catch fire on the catalyst
You should also have a slight smell of oil in the wheel arches when the engine is hot and the fan is running.
