Important! Before ordering an FEM or BDC control unit, it is necessary to secure the procurement authorisation of the customer, the vehicle owner or an authorised third party through presentation of original vehicle documents and an official photo ID! For authorised third parties a power of attorney on the part of the vehicle owner is also necessary. Copies of the specified authorisation credentials must be filed in the vehicle records. ***** ***** ***** ***** ***** ***** ***** *****
