BMW:
On BMWs we need both the Cluster and EWS/CAS. Depending on the year, make, and model, the CAS/EWS is located usually in the kick panel under the dash. To find the exact location, the service department at your dealership can provide you with the exact location depending on your VIN number.
Mercedes:
For Mercedes we will need the Cluster and EZS. The EZS the ignition module where the key goes into. Both are necessary because they communicate to each other to provide the mileage.
