Description
A2105450008 is a genuine Mercedes-Benz electronic ignition switch assembly known in the market as an EIS/EZS unit. This exact OEM number identifies the ignition switch function, while Marquardt number 33000201 is a corresponding manufacturer reference on the same unit family. This component is the dashboard-mounted ignition authorisation and switching module used within Mercedes electronic start and drive authorisation systems. It is an EIS or EZS ignition switch rather than a general ECU, and belongs in the ignition switch category rather than a generic immobilizer module group. This used OEM unit is suitable for buyers seeking the exact numbered replacement component shown in the title. Identification should always be confirmed by matching the full part number on the housing and label before purchase or installation. Compatibility, coding and specifications should be confirmed by the buyer.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
