4F0998281 Rear EPB Actuator Motor, 12-TORX Big Teeth, Compatible with Audi A6 C6 2004-2011, Q3 2011-2018, A4 B8 2007-2016, Direct Replacement

This 12-TORX big tooth rear electronic parking brake motor is a direct replacement for cross-reference OE part numbers 4F0998281, 4F0998281B, 32335478, 8K0998281, fits both left and right rear wheel positions, and is 100% compatible with Audi models including A6 C6 generation (2004-2011, including S6, Allroad variants), Q3 8U generation (2011-2018, all trim levels), A4 B8 generation (2007-2016, all trim levels), A5 (2007-2017) and Q5 8R generation (2008-2017), perfectly matching the original vehicle's rear brake caliper EPB actuator specifications with 12-tooth TORX big gear design. It is the core driving component of the rear electric parking brake system, responsible for driving the rear brake caliper piston to complete parking brake locking and releasing operations, effectively solving common EPB system failure symptoms including handbrake not engaging/releasing, abnormal noise during operation, parking brake warning light illumination, and related OBD fault codes specific to these Audi models, avoiding safety risks caused by failed parking brake function, especially suitable for luxury car daily commuting, long-distance travel and high-performance driving scenarios. Each motor adopts high-torque copper winding core and high-strength alloy steel 12-TORX big gear set, passes 50,000+ parking brake cycle tests under extreme temperature (-40℃ to 85℃) and vibration conditions, with waterproof and dustproof sealing reaching IP67 rating, service life 40% longer than ordinary aftermarket motors with small teeth design. The 1:1 original mounting interface and electrical connector design requires no coding or modification, supporting plug-and-play installation, suitable for both professional luxury car repair shops and DIY Audi owners.
