Key Enhancements in CGDI A2 V041

Extended Dongfeng Model Support – Smart Keys & Immobilizer

This update significantly widens the tool's compatibility with Dongfeng's latest electric and combustion models. Below are the newly added or improved functions:

Dongfeng Fengguang 580EV – Immobilizer Integration

For the Fengguang 580EV, technicians can now directly access the immobilizer control unit, enabling smooth key registration and security code synchronization.

• Added: Full immobilizer system access

Dongfeng Aeolus Family – Smart Key System Activation

The V041 software now supports smart key programming for the following Aeolus variants:

• Aeolus A60 (Six China specification)
• Aeolus AX7 PLUS

With these additions, the CGDI A2 becomes a one-stop solution for modern Dongfeng service bays.

Refined Model Classification – Aeolus Yixuan & E70

The development team has reorganized the internal database for the Aeolus Yixuan series and the Aeolus E70, reducing misidentification and shortening the time needed for vehicle detection and key preparation.

Mercedes-Benz Fixes & Operational Improvements

Beyond Dongfeng expansion, this release directly addresses several pain points reported by Mercedes-Benz specialists.

W207 Dealer EIS Writing Failure Resolved

A persistent error that occasionally interrupted dealer-level EIS writing on the Mercedes-Benz W207 chassis has been eliminated. This ensures reliable key personalization and ignition lock matching.

W215 AKL Quick Data Collection Fixed

For W215 models, the all-keys-lost procedure previously suffered from intermittent data collection failures. V041 stabilizes the acquisition process, allowing technicians to retrieve required security data without repeated attempts.

In-Software Key Matching Instructions

To reduce guesswork, step-by-step operation guides for key matching functions are now embedded directly into the software interface. This reduces training time and minimises errors during live jobs.

• Broader Dongfeng vehicle coverage – including EV and new-energy models
• Greater reliability in Mercedes-Benz EIS and AKL routines
• Improved model recognition accuracy for faster workflow
• Comprehensive on-screen assistance for key matching
• Reduced downtime and higher first-time success rates
• Enhanced overall software stability and responsiveness
