WHAT WE RESOLVE
C118 (2020-2026) common module and ADAS issues
- ADAS calibration drift Watch for calibration needs after windshield, bumper, suspension, camera, or radar work. 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.
- Gateway, key, and immobilizer access Gateway, key, and immobilizer procedures are represented by 18 merged security records. Access and all-keys-lost support varies by 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 examples 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.
Can you program keys or immobilizer systems for Mercedes-Benz CLA (2020-2026)?
Yes, where the VIN and security workflow support it. The generation data includes 18 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 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 work typically depends on module condition, donor data, and shipping window.
Is Mercedes-Benz CLA (2020-2026) 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.
