WHAT WE RESOLVE
W205 (2015-2021) common module and ADAS issues
- ADAS calibration drift Watch for calibration needs after windshield, bumper, suspension, camera, or radar work. Documented systems include Front Multi-Purpose Camera (Active Distance Assist / Pre-Safe) (2015), Front Long-Range Radar (Active Distance Assist DISTRONIC) (2015), Active Lane Change Assist (2015), and Blind Spot Assist / Rear Cross-Traffic Alert (2015). Year-marked systems apply only to the shown range.
- SRS crash-data and warning light SRS service can involve SRS Control Unit (2015-2019), SRS Control Unit, and SRS Control Unit (variant) (2015-2016). 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 C-Class (2015-2021) modules?
Yes. Core Auto Logic supports generation-scoped module programming for the Mercedes-Benz C-Class (2015-2021). 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 (2015-2021)?
The Mercedes-Benz C-Class (2015-2021) generation currently shows 89 core module records across ECU/PCM, BCM, TCU/TCM, ABS/EBCM, and SRS groups. SRS modules include SRS Control Unit (2015-2019), SRS Control Unit, and SRS Control Unit (variant) (2015-2016). Part numbers and module variants must be confirmed for your exact year/VIN. Reference part number: 0 285 011 400 (2015-2019) - confirm for your exact year/VIN.
Does Mercedes-Benz C-Class (2015-2021) need ADAS calibration after glass or collision work?
The merged generation data documents 39 ADAS systems, including Front Multi-Purpose Camera (Active Distance Assist / Pre-Safe) (2015), Front Long-Range Radar (Active Distance Assist DISTRONIC) (2015), Active Lane Change Assist (2015), Blind Spot Assist / Rear Cross-Traffic Alert (2015), and Active Parking Assist with PARKTRONIC (2015). Calibration triggers include Windshield Replacement (2015-2018), Front Bumper Repair or Replacement (2015-2018), Rear Bumper Repair or Replacement (2015-2018), and Any Collision (2015-2018). 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 (2015-2021)?
Yes. The generation data includes 49 SRS records, including SRS Control Unit (2015-2019), SRS Control Unit, and SRS Control Unit (variant) (2015-2016). 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: 0 285 011 400 (2015-2019) - confirm for your exact year/VIN.
Do all Mercedes-Benz C-Class (2015-2021) years use the same parts?
No assumption should be made across the full span. The generation page merges rows across 2015-2021; 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 C-Class (2015-2021)?
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 C-Class (2015-2021) 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.
