A used OEM Audi Power Brake Booster, genuine part number 8W0612103B (also replaces 8W0612107). This booster amplifies the force you apply to the brake pedal, making stops effortless. When it fails, you'll notice a rock-hard pedal or significantly longer stopping distances. It's compatible with various 2.0L turbocharged four-cylinder and 2.9L/3.0L V6 engine variants from Audi A4 through RS5 Sportback models.
