2008 S63 gasoline
Having numerous problems with abs lights and steering going stiff. Also parking brake and headlamp problems .
Im told its most likely the abs pump but also being told it could be related to the Yaw (acceleration rate sensor) sensor.

Does anyone know where this sensor is located to be replaced?

It should be in the trunk.... in the middle... right under the fuse box/rear sam.

I don't know specifically for the S Class, but the yaw sensor is typically located under the driver or passenger seat, mounted on the level floor as close as possible to the car's center of gravity. The yaw sensor measures rotation around the car's axis, which is where the center of gravity is located. If it's faulty you would be getting errors from the ESP, or the ESP acting up.

Several unrelated problems? SAM is your suspect.
