Genuine used BMW OEM matched engine immobilizer / security electronics set.
This set includes the Continental MSD85.1 DME, Siemens VDO CAS3, BMW key and the associated Start/Stop / key reader assembly shown in the photos.
The DME, CAS and key were removed together and are being sold as a matched set. This is useful when replacing damaged immobilizer or engine management electronics because the supplied DME and CAS retain their original synchronization with the supplied key.
This is a genuine BMW factory electronic set, not aftermarket.
You will receive exactly the components shown in the photos.

⚠️ Important Information
This is a matched DME + CAS3 + key set.
Because the supplied DME, CAS and key belong together, the immobilizer authorization between these supplied components remains matched.
However, depending on the recipient vehicle, installation may still require Order / configuration coding
