This failure mode presents a significant safety hazard because the vacuum system controls critical engine components, including turbocharger wastegates and exhaust flaps. Contamination of these components can lead to sudden loss of power, "limp mode" activation while driving at highway speeds, or unexpected engine behavior, increasing the risk of a crash.…
