Mercedes-Benz W204 Electronic Steering Lock Module - Used Original Parts

Diagnosis and Common Symptoms

From a workshop perspective, the W204 platform's Electronic Steering Lock (ESL/ELV) is a frequent and predictable point of failure. The primary issue stems from the wear of the internal motor, leading to a complete no-start condition. The vehicle's Drive Authorization System will not permit ignition if it cannot confirm the steering column is unlocked.

Common observed symptoms include:

• The key turns in the Electronic Ignition Switch (EIS), but there is no electronic response—the dashboard remains dark, and the engine does not crank.
• The steering wheel remains mechanically locked and will not release after key insertion.
• A faint whirring or clicking sound from the steering column area may be heard upon key insertion, which is the sound of the ESL motor attempting to actuate, followed by silence.
• Diagnostic scans using STAR/XENTRY will typically reveal fault codes related to the ESL, such as A25464 ("Steering lock has a malfunction") or A25408.
