Detailed Product Overview

Part number 06E903133R is an accessory drive belt tensioner designed to maintain correct belt tension across the engine speed range. For Audi A4, A4 Quattro, A5 Quattro, A6, A6 Quattro, A7 Quattro, Q5, S4, S5, SQ5, Q7, and Porsche Cayenne applications, proper tension helps the accessory drive system operate smoothly and keeps the belt tracking correctly on the pulleys. The OE-dimensioned construction supports accurate alignment, while the bearing and spring design are selected to match the demands of the original system.

This part cross-references Continental 49493 for the same application.

What It Helps Address

• Belt squeal caused by weak or inconsistent tension
• Erratic belt tracking from worn tensioner components
• Noise from a rough or failing tensioner bearing
• Reduced accessory drive stability under heat and vibration
• Premature belt wear related to misalignment or poor tension control

Installation Notes and Tips

Verify the vehicle’s engine configuration and existing tensioner style before installation. Confirm the belt path, pulley alignment, and mounting points match the original setup on your Audi or Porsche application. Inspect the accessory drive belt and related pulleys for wear at the same time, since a worn belt system can shorten the life of the new tensioner.

Quality Assurance

URO manufactures this tensioner to OE dimensions with a sealed NTN/NSK bearing and materials selected for heat and vibration resistance. Part number 06E903133R includes a 24 Month Unlimited Mileage Warranty.
