Frequently Asked Questions

Is this tensioner compatible with standard non-hybrid models?
No. This specific tensioner (part number 057903133AK) is engineered strictly for high-end longitudinal engine layouts (V6 TDI and V8 engines) utilizing the 48V mild-hybrid system with a Belt Starter Generator. Standard models with traditional 12V electrical infrastructure and classic alternators utilize a completely different mechanical spring tensioner.
Should I replace the serpentine belt when installing this tensioner?
Absolutely. If your old tensioner failed or lost its holding capacity, the V-ribbed belt has likely slipped, stretched, or developed microscopic structural heat cracks. Running an old belt on a new tensioner risks immediate belt failure. Always replace the serpentine belt (V-ribbed belt) as standard practice during this service.
Does this assembly include new installation mounting hardware?
Typically, the factory-sealed box includes the tensioner assembly itself. Because the mounting bolts are frequently under extreme torque loads and are often torque-to-yield (one-time use) in Audi repair procedures, it is highly recommended to inspect and purchase a supplementary hardware kit or replacement screws if dictated by the service manual.
Can a bad tensioner leave me stranded?
Yes. If the belt tensioner collapses or its internal dampening completely fails, the serpentine belt can snap or walk right off the pulley tracks. If this happens, you will immediately lose power steering, mechanical cooling loops, and your alternator/starter generator function, rendering the vehicle completely inoperable within moments.
