This used genuine OEM Belt Tensioner, part number 079903133BF, also replaces 079903133BG, is a direct pull from a donor vehicle. Designed for the 4.0L twin-turbo V8 found in the Audi S6, S7, S8, and RS7, this tensioner maintains proper drive belt tension to prevent slipping, noise, or accessory failure. A failing tensioner can cause belt squeal or premature wear, making this a critical component for the serpentine drive system.
