Why does it need to be replaced?The oil separator returns oil vapors back to the engine, separating them from the exhaust gases. Over time, its diaphragm and valves wear out, leading to a number of serious problems:- Increased oil consumption (oil burn): A faulty unit begins to leak oil into the intake manifold, where it burns in the cylinders.- Unstable engine operation: A torn diaphragm compromises the seal, causing excessive air intake. The engine begins to misfire, RPMs fluctuate, and the Check Engine light comes on.- Failure of oil seals and gaskets: If the valve inside the oil separator seizes (it stops relieving pressure), excessive pressure builds up in the engine crankcase, causing oil to be forced out through the crankshaft oil seals and the valve cover gasket.- Carbon buildup: Oil vapors entering the intake valves cause a thick layer of solid carbon deposits to form, which over time reduces engine power.On average, this part is replaced at 100,000 to 150,000 km, but if you notice a sudden increase in oil consumption or erratic engine speed, the unit requires immediate inspection.The BL model is the latest, upgraded version of the original oil separator (often installed to replace older versions to address oil consumption issues).fit for Audi: A6Q 2019-2026 Audi A6/S6/Avant quattro (Local)AQ8 2019-2027 Audi Q8 (Local)A7 2019-2026 Audi A7 Sportback (Local)A1 2019-2027 Audi A1 (Local)A3RS3 2022-2027 Audi A3/S3/RS3/Sportb./Lim.
