What is the average lifetime of an Audi A6 engine?

I've been thinking about buying a used Audi A6 and I wanted to know the average lifetime of the engine. I'm worried about potential high costs for repairs or replacements.

From personal experience, the average lifetime of an Audi A6 engine can vary greatly depending on how well it's maintained. I've seen them last anywhere from 150,000 to 250,000 miles.

As a mechanic, I've seen Audi A6 engines last well over 300,000 miles with regular maintenance. The key is to keep up with oil changes and other necessary repairs.
