Tools we use for this vehicle
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.
ADAS scan, setup, and verification
Autel, Launch Tech, Topdon
Used where aftermarket coverage supports the procedure; OEM software remains required for locked factory routines.
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

Documented systems include Front Mono Camera (Driver Assistance Package) (2020), Front Short/Medium-Range Radar (Active Brake Assist) (2020), Blind Spot Assist / Rear Cross-Traffic Alert (2020), and Active Parking Assist / Parktronic (2020). Year-marked systems apply only to the shown range.
- SRS crash-data and warning light SRS service can involve SRS Control Unit. 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.
FREQUENTLY ASKED QUESTIONS
FAQ
Can you program Mercedes-Benz CLA (2020-2026) modules?
Yes. Core Auto Logic supports generation-scoped module programming for the Mercedes-Benz CLA (2020-2026). 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 CLA (2020-2026)?
The Mercedes-Benz CLA (2020-2026) generation currently shows 58 core module records across ECU/PCM, BCM, TCU/TCM, ABS/EBCM, and SRS groups. SRS modules include SRS Control Unit. Part numbers and module variants must be confirmed for your exact year/VIN. Reference part number: A11790087000285011949 - confirm for your exact year/VIN.
Does Mercedes-Benz CLA (2020-2026) need ADAS calibration after glass or collision work?
The merged generation data documents 17 ADAS systems, including Front Mono Camera (Driver Assistance Package) (2020), Front Short/Medium-Range Radar (Active Brake Assist) (2020), Blind Spot Assist / Rear Cross-Traffic Alert (2020), Active Parking Assist / Parktronic (2020), and Rear View Camera (2020). Calibration triggers include Windshield Replacement (2020), Front Bumper Repair (2020), Rear Bumper Repair (2020), and Any Collision (2020). Procedure type is VIN-specific scan-tool procedure; verify exact requirements by VIN before setup.
Can you reset the airbag module on Mercedes-Benz CLA (2020-2026)?
Yes. The generation data includes 18 SRS records, including SRS Control Unit. 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: A11790087000285011949 - confirm for your exact year/VIN.
Do all Mercedes-Benz CLA (2020-2026) years use the same parts?
No assumption should be made across the full span. The generation page merges rows across 2020-2026; 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.
How long does service take for Mercedes-Benz CLA (2020-2026)?
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 service is available nationwide. Exact service eligibility is confirmed from the year, VIN, module, and requested scope.
Is Mercedes-Benz CLA (2020-2026) service mobile or mail-in?
Mobile service covers DFW on-vehicle diagnostics, post-repair coding, and supported module work. Mail-in module service is available nationwide. We confirm the active path for your exact year, VIN, module, and requested scope before service.
