weird leak of ?

Have a 2007 350 CLK convertible, 55,000 miles.

If it is not driven for a few days, I note a small stain of oil like liquid on the garage floor (maybe 3 drops) . Clearly fresh each time. Coming from the driver's side, under the engine compartment.

The local mechanic removed the protection plates below the engine bay and sees nothing. There was no oil stain on the inside of the plate which seems to cover the entire engine compartment.

What's going on? Should I be concerned? I assume the car will warn me if transmission or oil levels fall.

There is no warning light for low transmission fluid. If the fluid is red it is from the transmission.

It will tell to to add oil if it goes low.

Could that be morning water condensation washing down oils from the block?

Thanks, I hope so.

BUT- It is it normal for oils to leak out of the block?

Only when gaskets or seals have expired allowing oil to seep out.

Could this happen at 55,000 miles?
I hope not, this sounds like a major problem.

Valve cover gaskets on a 6-7 year old car are not uncommon. Not a bad job to do or have done.

It could be power steering fluid from a $1 o-ring at the bottom of the fluid reservoir. If it were mine I would have it looked over by an honest mechanic to see where it is coming from.

Please post back here before allowing any work to be done once the source of the leak is found.
