Ring in oil pan? M112 E32
I am replacing my oil pan gasket and I found a torn up plastic ring hanging from the oil pump.
It is a hard plastic black ring, apr. 1.5 to 2 inch (4-5 cm) in diameter with grooves on the outside.
It reminds me of the seal ring of an oil bottle but I would like to make sure it is not some part of the engine.
My oil pump was replaced a couple of months ago when I bought the car.

This is one of the causes that coolant mixed with engine oil.
Is this the right part number for the O-rings? A1129970845. I would like to compare material and size.
It looks like a rubber ring. I am pretty sure the ring I found is hard plastic.
no idea where that came from as most of the hard parts eemed intact, never seen any plastic parts missing or broken.
