The Electronic Steering Lock ELV or ESL is also a vehicle control unit for some Mercedes Benz and its main function is to lock the steering column and to verify the data provided by the immobilizer system. Mercedes Benz ESL/ELV (ELV is an acronym for 'Elektrische Lenkungsverriegelung', which in English means 'electric steering lock').

This are some common diagnostic trouble codes (DTCs) associated with the Mercedes-Benz Electronic Steering Lock (ESL/ELV) and the Electronic Ignition Switch (EIS/EZS) modules. These codes often indicate problems that can prevent the car from starting.

Electronic Ignition Switch (EIS) fault codes

The EIS or EZS is the central module that authenticates your key and communicates with the steering lock.

  • A22449: An internal electrical fault within the electronic ignition lock has occurred.

Electronic Steering Lock (ESL) fault codes

The ESL or ELV is the motor and mechanism that physically locks the steering wheel.

  • A25407: A mechanical fault has occurred within the electric steering lock. This is often caused by a worn-out motor or a jammed locking mechanism.

  • A25408: There is a signal fault or an incorrect message from the electric steering lock. This is a communication error between the ESL and other control units.

  • A25409: There is a general component malfunction within the electric steering lock.

  • A25464: An implausible signal is being received from the electric steering lock.

  • 9003: No feedback was received from the ESL/ELV during an unlocking attempt. This is often seen when the steering lock motor fails to disengage.

  • 9005: A communication error has occurred with the ESL/ELV control unit.

Symptoms of a failed ESL

A failed ESL will typically cause the following symptoms:

  • The car will not start and the steering wheel remains locked.

  • When you insert the key, the dashboard lights do not come on.

  • There is no release sound from the steering lock mechanism when you insert the key.

  • You may see a message on your dashboard such as "Key not detected" or a steering lock symbol.

  • If you can turn the key to on position a dashboard message "take key from ignition" will appear, the dashboard or radio will not turn on, and the engine will not crank

To troubleshooting and repair you will need a specialized diagnostic tool, such as Mercedes' own XENTRY system or a high-end aftermarket version, to accurately read these specific codes and diagnose the fault. In many cases, the only solution is to replace the faulty ESL module. A new module must be coded and programmed to the vehicle. Some repair shops offer a permanent bypass solution using an "ESL emulator." This electronic device mimics a functional steering lock, allowing the car to start. However, it requires a complete understanding of the system's programming.
