Hello fellow members.
I have a 2004 2.5 diesel BDG engine cabriolet that has low oil pressure, my mechanic tells me that the pressure is 4 bar when it should be running at 8 bar & the oil warning light comes on intermittently but not all the time. I have always changed the oil every 10k & put in top brand oil & the cr has done 140k. I am wondering if the oil pump is on its way out or if it could be the pick up filter that has some debris on the filter restricting the oil flow. I am also wondering if the oil pump that is fitted into my car is fitted in any other make/model of Audi as i dont seem to be able to find any pumps on line.
