| 11002864 | No Bass or a cracking noise can be heard from the bass speakers. |
| 11000563 | At low outside temperatures (below 40 degrees F) and slow driving speeds (i.e. when parking, maneuvering)with a large steering angle, the front end can be slightly axially misaligned. |

The groaning noise always occurs when either a ventilation flap, air stratification flap or the recirculated airflap moves to a different position. Due to the complex design of the heating and air-conditioning unit, the kinematics causing it (top or bottom,left or right) may not be able to be precisely located. Depending on the vehicle model, the number of servomotors (and the associated kinematics unit) varies.Various models use either 2 or 3 servomoto |
