BMW E39 E38 EWS3 Immobilizer Relay ECU Ignition Control Unit – 6905668 – Used

This is a used, original BMW EWS3 immobilizer control unit, also known as the ignition relay or access system.

It's pulled from a BMW, fully operational, and ready to go.

Part numbers include 61 35 6905668, 61356905668, and 6905668.

It fits E39 5-series and E38 7-series models with the EWS3 system.

Made in Germany, so it's genuine quality.

It may have some minor cosmetic wear from previous use, but it functions as intended.

Installation is straightforward—plug and play if you're replacing a faulty unit.

The placement is in the front of the vehicle (usually behind the glovebox or in the e-box).

If your BMW has starting issues or anti-theft gremlins, this might be your fix.
