Can you program Mercedes-Benz C-Class (2008-2014) modules?
Yes. Core Auto Logic supports generation-scoped module programming for the Mercedes-Benz C-Class (2008-2014). 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 C-Class (2008-2014)?
The Mercedes-Benz C-Class (2008-2014) generation currently shows 62 core module records across ECU/PCM, BCM, TCU/TCM, ABS/EBCM, and SRS groups. SRS examples include SRS Control Unit, SRS Control Unit (2008-2009), and SRS Control Unit (variant) (2009-2012). Part numbers and module variants must be confirmed for your exact year/VIN. Reference part number: 0 285 010 229 - confirm for your exact year/VIN.
Does Mercedes-Benz C-Class (2008-2014) need ADAS calibration after glass or collision work?
The merged generation data documents 3 ADAS systems, including Rear View Camera (PARKTRONIC), PRE-SAFE® Brake - Forward Camera (Stereo), and PRE-SAFE® Brake - Forward Radar (77GHz). Calibration triggers include ECM/ME Replacement and ABS/ESP Module 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 C-Class (2008-2014)?
Yes. The generation data includes 36 SRS records, including SRS Control Unit, SRS Control Unit (2008-2009), and SRS Control Unit (variant) (2009-2012). 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: 0 285 010 229 - confirm for your exact year/VIN.
Do all Mercedes-Benz C-Class (2008-2014) years use the same parts?
No assumption should be made across the full span. The generation page merges rows across 2008-2014; 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 C-Class (2008-2014)?
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 C-Class (2008-2014)?
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 C-Class (2008-2014) 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.
