Yanhua ACDP Module 39: Professional Mercedes-Benz HU7 Mileage Correction Tool Yanhua ACDP Module 39 is a professional tool designed for mileage correction on Mercedes-Benz vehicles equipped with the HU7 Instrument Module, covering models from 2019 to 2024. Key Functions: *   Supports mileage correction for the Mercedes-Benz HU7 instrument module (applicable to models A206, A223, A177) with chip models R7F7015923 or R7F7015924.*   Please note: For mileage correction on the MB HU6 instrument module (A167/A213/A247) with chip model R7F701403, the Yanhua ACDP Module 37 is required. Important Notice: *   ACDP Module 39 performs mileage correction in the instrument cluster only.*   The package includes one MB HU7 Emulator by default. This emulator is necessary to prevent a black screen on the dashboard and must be permanently soldered onto the vehicle (one emulator per car). Additional emulators can be purchased separately (available as one MB HU7 Simulator or a pack of 5 MB HU Emulators).*   This module works with both ACDP2 and ACDP1 hardware. Please note that the ACDP hardware unit itself is not included in this package.
