Frequently Asked Questions
Find answers to common questions about torque specifications
Q1 What type of drivetrain does the 1997-2004 Audi A6 use?
What type of drivetrain does the 1997-2004 Audi A6 use?
The 1997-2004 Audi A6 is available with either front-wheel drive (FWD) or quattro all-wheel drive (AWD) systems. The quattro system uses a Torsen (Torque-Sensing) center differential to distribute torque between the front and rear axles, typically in a 50:50 ratio under normal conditions.
Q2 What is the gear ratio for the 1997-2004 Audi A6 manual transmission?
What is the gear ratio for the 1997-2004 Audi A6 manual transmission?
The manual transmission in the 1997-2004 Audi A6 typically has a final drive ratio of 4.11:1 for the 5-speed manual and 3.89:1 for the 6-speed manual. Gear ratios vary depending on the engine and trim level.
Q3 How often should the drivetrain components be inspected?
How often should the drivetrain components be inspected?
Audi recommends inspecting drivetrain components, including the driveshaft, differential, and CV joints, every 30,000 miles or as part of routine maintenance. Severe driving conditions may require more frequent inspections.
Q4 What is the torque specification for the driveshaft bolts?
What is the torque specification for the driveshaft bolts?
The torque specification for the driveshaft bolts on the 1997-2004 Audi A6 is 70 Nm (52 lb-ft) for the front driveshaft and 80 Nm (59 lb-ft) for the rear driveshaft. Always use a calibrated torque wrench and follow Audi's tightening sequence.
Q5 Can I replace the Torsen differential with a conventional differential?
Can I replace the Torsen differential with a conventional differential?
No, the Torsen differential is integral to the quattro system's performance and cannot be replaced with a conventional differential without significant modifications. Using non-genuine parts may void the vehicle's warranty and compromise safety.
