The DAS 3 ELV (ESL - Electronic Steering Lock) in Manual and 5G Tronic (722.6) Mercedes-Benz Cars: An In-Depth Technical Guide
The DAS 3 ELV (ESL - Electronic Steering Lock) is a crucial component in modern Mercedes-Benz cars, providing advanced security features and ensuring driver safety. It is installed in both manual and 5G Tronic (722.6) cars and plays a key role in immobilizing the steering wheel and preventing unauthorized access. In this comprehensive technical guide, we'll take a deep dive into the DAS 3 ELV, exploring its functions, installation, and common fault codes.

This feature makes it nearly impossible for thieves to steer the vehicle or tow it away. Additionally, it provides enhanced security features by requiring a unique code from the key fob to unlock the steering wheel and start the engine. Furthermore, the DAS 3 ELV is integrated into the DAS 3 anti-theft system, providing an additional layer of security.
