Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
DSC Sensor
The lateral-acceleration and yaw-rate sensors are combined in a single housing and designated the DSC sensor. The active front steering system is also provided with a second DSC sensor in addition to the DSC sensor fitted as standard. DSC sensor 1 is located under the right front seat. DSC sensor 2 is located under the left front seat. See Fig 1.
The two DSC sensors are technically identical but coded by means of the software so that they cannot be mixed up. DSC sensor 2 is used for redundant signal acquisition of yaw rate and lateral acceleration. Both sensors supply yaw-rate and lateral acceleration signals. The use of two DSC sensors makes it possible to perform the plausibility check.

- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
