Audi A4 Accessory Belt & Tensioner Replacement DIY (2017-2024 Audi B9 A4, A5, Sportback, Allroad)

►The accessory drive belt plays a crucial role in how your vehicle operates. It rides on the crankshaft pulley and wraps around the alternator and A/C compressor pulleys in the Audi B9 A4, but it may also drive the water pump and power steering pump on other engines. Damage to the pulleys, the belt, or the belt's tensioner can spell disaster for all of the driven pumps and parts, as a snapped belt is a likely outcome. The accessory belt system in the B9 Audi A4 features the belt and its tensioner. Both components can be pretty worn around the 80,000-mile figure, so be sure to check them around then. Most often, you'll hear the tensioner pulley's bearing making a humming or rattling sound as it goes bad. It's best to always replace the tensioner and belt together to ensure one doesn't leave you stranded soon after the other.
