I had my 2016 C300 serviced yesterday at a local shop with a great reputation. They found a potential leak that they cannot identify (picture attached). The fluid is on the power streering unit, but does not appear to be power steering fluid. Suggested I take it to the dealership for diagnosis as they couldn't find any bulletins. Anyone have any ideas what this might be?

Mechanic can't identify this fluid. Suspects it may be some aftermarket corrosion protection. Doesn't seem to be power steering fluid even though it is on the power steering unit.

There is no power steering unit fluid as it uses an electronic power steering rack. That stuff is there to prevent corrosion. Nothing to worry about.
