Active grille shutter fail after shop visit
Active grille shutter fail after shop visit
Had to get my pistons replaced. Under warranty which is good but now from the dealership it comes out with a code about the active grille shutters not working and a check engine light is on.
Is this a simple fix? It was working before I dropped the car off to get the engine fixed initially.
Anyone do this themselves?
