Audi Mechanic: Dan, Technician replied 10 months ago

Test engine oil pressure using an external mechanical test gauge. Specification with the engine hot is 1.3 Bar (19.0 PSI) at idle and 3.5 to 4.5 Bar (50.7 to 65.0 PSI) at 2000 RPM. This vehicle has a dynamic engine oil pressure warning system which detects low oil pressure both at idle and 2500 RPM. If oil pressure is low at either condition the oil light should illuminate and at 2500 RPM a buzzer will sound. 1.8L Turbo engines can exhibit severe oil sludging in the turbo oil lines. This sludge buildup can drop into the oil pan and be picked up by the oil pump pickup. In severe cases oil pump pickup can become restricted and cause an oil starvation problem. Sufficient loss of oil pressure can damage the engine and turbo bearings and may eventually lead to engine seizure. If lower than normal oil pressure is indicated, an inspection of the oil pan and oil pump pickup should be performed. Remove oil pan and observe the condition of the oil. Excessive sludge should not be present. Visually inspect the oil pickup screen for deposits. The screen must be clean. Let me know if you have questions, thanks .
