The Electronic Steering Lock (ESL) in Mercedes Benz W204, C207, A207, and W212 models from 2007 onwards is a commonly encountered issue for both vehicle owners and repair professionals. When the ESL malfunctions, it can lead to significant repair expenses and inconvenience for the vehicle owner. Recognizing signs such as noisy or slow operation, or encountering specific faults, it is crucial to address the issue promptly to avoid a non-operational vehicle and substantial repair costs.

​

Common ESL faults include:

1. Inability to start the vehicle, and the steering remains locked.

2. Noisy steering lock operation.

3. Key turning in the Electronic Ignition Switch (EIS / EZL) without starting the vehicle.

4. Absence of dashboard lights when turning the key in the EIS.

5. Inaudible operation of the Electronic Steering Lock (ESL / EVL) when the key is inserted.

6. Steering wheel immobility even with the key in the EIS.

7. Fault codes such as 9003 (N26/5 ESL / ELV control unit) indicating no feedback during unlocking and stress on the steering, and 9005 (N26/5 ESL / ELV control unit) indicating a communication fault.

To address these issues, Digi Auto Centre offers a prompt testing and remanufacturing service for electronic steering locks. The ESL undergoes a comprehensive testing and remanufacturing process. Opting for ESL remanufacturing instead of purchasing a new unit eliminates the need for additional dealer security programming or coding once the unit is returned. Reinstallation of all components allows the vehicle to start and run seamlessly.

Removal of the ESL involves taking out the steering column, removing the retaining nut, and pushing in the stud. In cases of intermittent operation, tapping the ESL after inserting the key can unlock it. Once unlocked, disconnecting connection plugs and removing the ignition key enables the removal of the steering column, the nut, and pushing in the stud for ESL extraction. For stubborn ESL units that won't unlock, cutting the stud is required, and Digi Auto Centre can install a new stud during the process.
