If your inspector wants factory paperwork, you're chasing a warranty claim, or you just want the exact piece Audi installed, this is it: the genuine OEM crankcase breather hose, part 06E103207AR, not a reproduction.\u003c\/p\u003e\n\u003cp\u003eThe plastic in these hoses breaks down over time from heat, pressure, and oil vapor exposure. When it finally cracks, you get a vacuum leak, a rough idle, and a check engine light at a bad time. Replacing it with the genuine part means you're not guessing about fit or material quality, you're putting back exactly what came off.\u003c\/p\u003e\n\u003chr\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cstrong\u003eEngine Crankcase Breather Hose\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAn engine crankcase breather hose is a primary component of an engine's positive crankcase ventilation system, funneling pressurized air from the engine crankcase to the air\/oil separator, also known as the PCV valve. The PCV valve, or air\/oil separator, is designed to capture and remove oil vapors from the pressurized crankcase air, allowing them to drain back to the engine, while the pressurized air is fed to the intake side of the engine and utilized as part of normal combustion.\u003c\/p\u003e\n\u003cp\u003eAn engine develops positive crankcase pressure as a byproduct of the overall combustion process. Because of the combination of pressure, heat, and the air\/oil-vapor mixture traveling to the PCV valve, the engine crankcase breather hose is a common failure item within the PCV system and is crucial to your car's engine's performance and emissions compliance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEngine Crankcase Breather Hose Failure Symptoms\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCracks breaks, leaks: Over time, your engine crankcase breather hose can be easily damaged because of constant exposure to oil vapors, heat, and pressure from the engine. The engine oil can slowly break down the plastic or rubber materials, eventually causing an air leak. This can happen naturally, or because it is damaged from external contact.\u003c\/li\u003e\n\u003cli\u003eBroken connectors: Plastic can become brittle over time, especially when exposed to heat and oil, and it's easy to break one of the securing clips or connectors for a PCV hose, either during removal or during other services.\u003c\/li\u003e\n\u003cli\u003eBroken or damaged hose: Soft rubber or brittle plastic, depending on the material of the hose, can result in an obvious hole or split in an engine crankcase breather hose, usually accompanied by one of the other faults listed below.\u003c\/li\u003e\n\u003cli\u003eCheck Engine Light: Excessive unmetered air from a failed engine crankcase breather hose can result in a CEL for an air intake leak fault or other airflow-related diagnostic trouble codes.\u003c\/li\u003e\n\u003cli\u003eMisfire: A severe air intake leak can cause rough running and an engine misfire, a common side effect of a bad engine crankcase breather hose or PCV Valve\u003c\/li\u003e\n\u003cli\u003eOil residue on or around the hose or adjacent components: As engine crankcase vapors escape from a faulty engine crankcase breather hose, the hose, engine block, and adjacent components are likely to become visibly soiled with oil residue and moisture. In the most severe cases, you will smell burning or burnt oil, and you may need to degrease the area to determine the exact cause of the oil residue.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eBottom line:\u003c\/b\u003e if you want the exact part Audi built the car with, not a cross-reference, this is it.\u003c\/p\u003e\n\u003chr\u003e\n\u003cdiv class=\"product-fitment-section\" style=\"margin: 20px 0; font-family: inherit;\"\u003e\n\u003ch3 style=\"font-size: 1.1rem; margin-bottom: 10px; font-weight: bold;\"\u003eVehicle Fitment\u003c\/h3\u003e\n\u003cp\u003eThis genuine breather hose fits the 3.0L V6 supercharged platform across the Audi A6\/A7 (C7), A8 (D4), S4\/S5 (B8.5), and Q7 (4M).\u003c\/p\u003e\n\u003cdiv style=\"overflow-x: auto;\"\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; text-align: left; font-size: 0.95rem;\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"border-bottom: 2px solid #ddd; background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding: 10px; border: 1px solid #ddd;\"\u003eMake\u003c\/th\u003e\n\u003cth style=\"padding: 10px; border: 1px solid #ddd;\"\u003eModel\u003c\/th\u003e\n\u003cth style=\"padding: 10px; border: 1px solid #ddd;\"\u003eYears\u003c\/th\u003e\n\u003cth style=\"padding: 10px; border: 1px solid #ddd;\"\u003eChassis\u003c\/th\u003e\n\u003cth style=\"padding: 10px; border: 1px solid #ddd;\"\u003eEngine\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eAudi\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eA6\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e2016-2018\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eC7\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e3.0L V6 Supercharged\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eAudi\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eA7\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e2016-2018\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eC7\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e3.0L V6 Supercharged\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eAudi\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eA8\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e2015-2018\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eD4\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e3.0L V6 Supercharged\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eAudi\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eS4\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e2015-2016\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eB8.5\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e3.0L V6 Supercharged\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eAudi\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eS5\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e2015-2017\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eB8.5\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e3.0L V6 Supercharged\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eAudi\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eQ7\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e2017-2019\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e4M\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e3.0L V6 Supercharged\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003cp style=\"margin-top: 10px; font-size: 0.85rem; color: #555;\"\u003e\u003cem\u003e\u003cstrong\u003eNOTE:\u003c\/strong\u003e Genuine OEM part 06E103207AR, a supersession of 06E103207AE and 06E103207AJ, and part of the same interchange family as 06E103207AC, 06E103207AH, and 06E103207AP.
