To adjust the idle on a 2007 GTI, first ensure the engine is at operating temperature. Then, locate the throttle body and the idle air control (IAC) valve; adjustments can typically be made via a screw on the throttle body. Use a diagnostic tool to monitor the idle RPMs and make small adjustments as needed. Always refer to the vehicle's service manual for specific procedures and specifications.
