Turbo stops spooling and giving boost after starting and warming up

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! It's turbo time! The symptoms you describe—an initial good boost that diminishes after warming up—suggest a problem with either the turbo boost solenoid or its control circuitry. If the solenoid is failing or not receiving proper signals, it can cause inconsistent boost levels. You can perform a diagnostic scan to check for any pending or stored fault codes related to the turbo boost system. You can also check the boost pressure sensor and any wiring related to the solenoid and sensor. This will help pinpoint whether the solenoid or another component needs replacing. If you have any other questions, please call us at 877-913-1554! We'll gladly find you a certified RepairPal shop in your area!
