If you have over filled your engine oil, it will not "leak" unless you have completely filled the engine with oil and is pouring out where you put it in. However overfilling even as much as little as 1 quart can lead to catostophic engine damage as the crankshaft will spin into the oil in the pan causing it to foam and cause oil circulation problems throughout the engine leading to overheating and engine siezing.
in the top of the engine there is a cap with an oil can sign on it . Fill the oil in there. Be care not to over fill as it can cause the engine to cease!
There probaboy is a leak somewhere. Don't run it with the light on or you will need mega bucks repair. It's probably an oil pan/ gasket leak or engine gasket leak(i.e.head gasket)
An oil leak is always going to be out of the engine as the engine contains oil and the car does not. I think you are saying you are loosing oil with no apparent leak. If that is the case the engine is burning oil and that is why you see no leaks.
engine oil leak
If you have an engine oil leak on your 2002 Peugeot 206 1.4, you can use an oil stop-leak product to fix it.
When your engine turns over, there is an oil pump inside the engine that is being driven by the crankshaft. It is creating pressure by pumping oil throughout the engine. Most will achieve around 40 to 50 lbs. If there is a problem with any of the lines or gaskets in the system, it will leak when there is pressure. Try to locate the leak by washing the area that's leaking and watch it as someone turns the engine over. Most leaks of this sort aren't too hard to fix.
Put the oil fill cap back on!

Oil leaks can be hard to find. Wash the engine good. Keep the oil filled, and look daily for signs of oil, even underneath the engine to see where the leak is.
