Tool access for this exact year
Representative tool access paths for this exact model year, gated by the vehicle data and source packet we currently trust.
Factory scan, coding, and calibration access
Mercedes XENTRY Diagnosis / Mercedes DAS
Factory routines and secure server authorization control this path when aftermarket coverage is not enough for the VIN.
OEM subscription required Security gateway access required No practical workaround
Make-level OEM tool map plus exact-year gateway and ADAS fields.
ADAS scan, setup, and verification
Autel, Launch Tech, Topdon
Used where aftermarket coverage supports the procedure; OEM software remains required for locked factory routines.
Tool subscription required
Service-level scanner-vendor source packet plus exact-year ADAS records.
Bench cloning and chip-level recovery
Alientech / Autotuner / Orange5 / Scanmatik / Flex / VVDI2 / PCMFlash / CGDI / X-Prog
Used only when the module, donor data, EEPROM, MCU, or crash-data workflow requires bench or chip-level handling.
Bench/chip-level only

- ADAS calibration drift Watch for calibration needs after windshield, bumper, suspension, camera, or radar work. Documented systems include Forward Camera (Mobileye EyeQ4) - EQA MFA2, Forward Radar (77GHz) - Continental ARS (EQA), Blind Spot Monitor / Active BSD (EQA), and Rear View Camera (EQA). Year-marked systems apply only to the shown range.
- SRS crash-data and warning light SRS service can involve Airbag Control Unit (ACU) (EQA MFA2) (2022-2025), SRS-ECU (2022-2025), and Airbag Control Unit (ACU) (EQA MFA2) (2026). Part numbers and crash-data workflow are confirmed for the exact year/VIN.
- Replacement module setup ECU/PCM replacement programming, BCM configuration, TCU/TCM cloning, ABS/EBCM setup are represented in the merged generation data. Rows with year ranges do not apply to every model year; verify by VIN.
- Gateway, key, and immobilizer access Gateway, key, and immobilizer procedures are represented by 11 merged security records. Access and all-keys-lost support varies by year - verify by VIN.
FREQUENTLY ASKED QUESTIONS
FAQ
Can you program Mercedes-Benz EQA (2022-2026) modules?
Yes. Core Auto Logic supports generation-scoped module programming for the Mercedes-Benz EQA (2022-2026). The merged generation data includes ECU/PCM, BCM, TCU/TCM, ABS/EBCM, and SRS coverage. Rows marked with a year range apply only to that part of the span; unmarked rows are present across the merged generation data.
Which modules are documented for Mercedes-Benz EQA (2022-2026)?
The Mercedes-Benz EQA (2022-2026) generation currently shows 17 core module records across ECU/PCM, BCM, TCU/TCM, ABS/EBCM, and SRS groups. SRS examples include Airbag Control Unit (ACU) (EQA MFA2) (2022-2025), SRS-ECU (2022-2025), and Airbag Control Unit (ACU) (EQA MFA2) (2026). Part numbers and module variants must be confirmed for your exact year/VIN. Reference part number: A2539001900 (2022-2025) - confirm for your exact year/VIN.
Does Mercedes-Benz EQA (2022-2026) need ADAS calibration after glass or collision work?
The merged generation data documents 5 ADAS systems, including Forward Camera (Mobileye EyeQ4) - EQA MFA2, Forward Radar (77GHz) - Continental ARS (EQA), Blind Spot Monitor / Active BSD (EQA), Rear View Camera (EQA), and Park Distance Control (PDC) (EQA). Calibration triggers include Windshield Replacement, Front Bumper Repair or Replacement, Rear Bumper Repair or Replacement, and Mirror Replacement. Procedure type is VIN-specific scan-tool procedure; verify exact requirements by VIN before setup.
Can you reset the airbag module on Mercedes-Benz EQA (2022-2026)?
Yes. The generation data includes 7 SRS records, including Airbag Control Unit (ACU) (EQA MFA2) (2022-2025), SRS-ECU (2022-2025), and Airbag Control Unit (ACU) (EQA MFA2) (2026). Bench reset, cloning, and replacement setup are handled after part-number review. Any SRS part number shown for this generation is planning data only - confirm for your exact year/VIN. Reference part number: A2539001900 (2022-2025) - confirm for your exact year/VIN.
Do all Mercedes-Benz EQA (2022-2026) years use the same parts?
No assumption should be made across the full span. The generation page merges rows across 2022-2026; any row that does not span all data-bearing years is printed with its year range or treated as varies by year - verify by VIN. Part numbers always require exact year/VIN confirmation before ordering, cloning, or programming.
Can you program keys or immobilizer systems for Mercedes-Benz EQA (2022-2026)?
Yes, where the VIN and security workflow support it. The generation data includes 11 gateway, immobilizer, or key-security records. Gateway examples include Central Gateway Module. Key records are present in the merged generation data. Security access, all-keys-lost eligibility, and add-key workflows vary by year - verify by VIN.
How long does service take for Mercedes-Benz EQA (2022-2026)?
Most programming, cloning, SRS, and calibration jobs are quoted after VIN, DTC, part number, and repair-scope review. Labor time varies by year - verify by VIN before scheduling. Mail-in module work typically depends on module condition, donor data, and shipping window.
Is Mercedes-Benz EQA (2022-2026) service mobile or mail-in?
Both paths are available depending on the job. Mobile service covers DFW on-vehicle diagnostics, ADAS setup, key programming, and post-repair coding. Mail-in service covers ECU, BCM, SRS, TCU, ABS, and other bench module work nationwide. We confirm the correct path for your exact year/VIN before scheduling.
