Took my 300E to my mechanic today to check this low oil pressure problem out. I was hoping that it was the sender. Picked up car, mechanic says the oil pressure is reading between 8 psi at idle and 20 psi at 2500rpm with engine at operating temperature.

When the engine is cold the reading appear normal, if not high. (almost a 3 bar reading)

Looks like it is two problems he said. The first is the oil pump and the second is the lower seals. I will leave it with him next week for a few days while he reseals the lower end of the engine and replaces the oil pump.

Has anyone else had this problem and if so, what was the solution? Could there be anything else?

thanks
