The 2015 AudiA6 comes with a timing chain that is built to last the entire lifespan of the vehicle. Unlike a belt, you don't have to change it regularly, but if it needs replacement, it can be quite costly. Just think of a bike chain constantly moving and engaging with other components to understand how the timing chain functions. It ensures that the camshaft and crankshaft sprockets are always in sync to ensure the proper operation of the intake and exhaust valves each time the engine ignites. If the chain fails, it can lead to significant engine damage. Replacing this part in the A6 typically costs between $2,030 and $2,470, with labor accounting for around $1,650 to $2,090 of the total cost.
