With engine running at idle 1100 rpm have very very faint buzzing sound from oil pressure gauge. When at
about 1500 RPM have fairly loud "screeching" sounds from buzzer but only at about that rpm. Will
clean engine connections and check wiring at panel but anyone have this problem?
2003 C310 with M25XPC eng about 410 hours. Oil at proper level no leaks with
annual changes Eng does not use oil between changes (about 45 hours) Again noise only at those two rpm levels. Appreciate any thoughts.
