Detailed Description
Rein ABH0217 is an engine oil separator/breather valve made to replace the original component on select Audi vehicles. Rein positions this part as an OE-quality solution that mirrors the factory unit, making it a practical choice when servicing the crankcase ventilation system on applications such as the Audi S5, Audi A6 Quattro, Audi A8 Quattro, Audi R8, and Audi RS4. The ABH0217 is a standard replacement part, not a modified or performance version, so it follows the original equipment layout and function.
Compatible With 2008-2012 Audi S5, N/A; 2007-2011 Audi A6 Quattro, N/A; 2007-2010 Audi A8 Quattro, N/A; 2010 Audi R8, N/A, to 8/23/10; 2008-2009 Audi R8, N/A; and 2007-2008 Audi RS4, N/A. Use ABH0217 when you need a direct replacement oil separator for these factory applications.
Common Issues This Part May Address
- Oil vapor separation problems in the crankcase ventilation system
- Rough idle caused by a worn breather valve
- Vacuum-related drivability concerns from a failing separator
- Oil residue buildup from a damaged OE-style valve
- Check engine light conditions tied to crankcase ventilation faults
Installation Notes and Tips
Verify the original part number and engine application before installation. Because fitment varies by model year and, in one case, production date, confirm the vehicle matches the listed Audi S5, A6 Quattro, A8 Quattro, R8, or RS4 coverage before ordering. Inspect surrounding hoses and seals during service to ensure the crankcase ventilation system is restored correctly.
Quality Assurance
Rein Automotive markets this breather valve as an OE-quality replacement built to match the original manufacturer’s design for European vehicles. Part number ABH0217 is engineered as a direct replacement for factory-style service on the listed applications.
