2013 VW Tiguan P0299 Code: Supercharger Boost Failure Diagnosis and Solutions

Hello, My 2013 VW Tiguan began with intermittent check engine light warnings, which eventually stayed on permanently. A diagnostic scan revealed code P0299, indicating a failure in the supercharger under boost condition. The vehicle runs smoothly but lacks power and performance. I'm looking for guidance on what to inspect or repair first. Any recommendations on potential causes—such as faulty boost pressure sensors, turbocharger issues, or vacuum leaks? What are common fixes for this code in 2013 VW Tiguan models? Thanks for your help!
