I drive my 380 1-2 times aweek so it sits alot. Lately,I noticed the oil pressure stays at zero for ,somethimes, a minute before going to 3 bar after its' started. It may have sat for 4 days' before this.
I have cleaned the "pressure sender "connection and the engine does not make any oil starved noises. Pressure sending unit?
Also, i noticed the CD rom said to remove the "sending unit wire" before changing the filter. I didn't do that and does it matter?
thanks.
