The fault code U1008 indicates a communication issue between the engine control module and the transmission control module. The estimated repair time for this fault code is 1.0 hour. The cost of fixing this issue can vary depending on the hourly rate of the auto repair shop.

Most shops charge between $75 and $150 per hour for labor. Therefore, the total cost of fixing the U1008 fault code can range from $75 to $150.

The U1008 fault code indicates a problem with the Active Air Flap (AAF) system in your automobile. This system is responsible for opening and closing a flap between the radiator grille and radiator. During high-speed driving, the flap is closed to reduce air resistance and enhance driving stability.

The Engine Control Module (ECM) opens the flap function if the temperature inside the engine room rises.

If the AAF system is not working to factory specifications, the ECM will set the U1008 code, indicating a lost communication with the radiator shutter. It is important to have this issue addressed promptly to ensure proper functioning of your vehicle.
