If your Audi is equipped with a turbo and you've noticed a reduction in acceleration in addition to your check engine or glow plug light, your turbo boost pressure solenoid may need to be replaced or repaired. The N75 valve is vital to the health of your turbocharged engine, it controls when and how far to open the wastegate to allow boost pressure to be released.
Diagnosing a broken wastegate frequency control valve can be difficult, but a common symptom is a lack of boost pressure with no boost leak present in the system.
Replace your faulty N75 valve and restore turbocharger performance.
