BMW GS 95003-2 is the vehicle level member of the manufacturer's electromagnetic compatibility standard family, and the part numbering indicates that the subject is treated in more than one document, with the vehicle as a whole addressed separately from the components installed in it. The distinction matters because the two levels answer different questions. A component standard asks whether a unit will work when it is properly installed; a vehicle standard asks whether the car as delivered will work, with every option fitted, with the harness routed as it is in production and with the antennas and the entertainment system operating at the same time. Testing at this level is performed on a complete vehicle, before and after the powertrain is running, and the result is what supports the type approval and the manufacturer's own sign-off. Programme timing is usually driven by the availability of vehicles.
