The most common issue reported with Audi A4's turbocharger is turbo lag, where the engine hesitates before accelerating. This can be resolved by regular maintenance and keeping the turbo clean and properly lubricated.

Another issue that many Audi A4 owners face is a failing wastegate, which can cause inefficient boost pressure regulation. Wastegate replacement or repair is often recommended to resolve this problem.

Some drivers also complain about excessive oil consumption with their Audi A4's turbo, which can be due to leaks or improper lubrication. Regular oil changes and inspecting for any leaks can help prevent this issue.
