WHAT WE RESOLVE
1st Gen (2021-2026) common module and ADAS issues
- ADAS calibration drift Watch for calibration needs after windshield, bumper, suspension, camera, or radar work. Documented systems include Pilot Assist Forward Camera (Zenseact monocular) (2021), Pilot Assist Forward Radar (Zenseact) (2021), BLIS Radar - Front Corner (L/R) (2021), and BLIS Radar - Rear Corner (L/R) (2021). Year-marked systems apply only to the shown range.
- SRS crash-data and warning light SRS service can involve SRS Airbag Control Module (ACU) (2021), Occupant Weight Sensor (OWS), and SRS-ECU / ACM (2021-2024). 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 Polestar 2 (2021-2026) modules?
Yes. Core Auto Logic supports generation-scoped module programming for the Polestar 2 (2021-2026). 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 Polestar 2 (2021-2026)?
The Polestar 2 (2021-2026) generation currently shows 29 core module records across ECU/PCM, BCM, TCU/TCM, ABS/EBCM, and SRS groups. SRS modules include SRS Airbag Control Module (ACU) (2021), Occupant Weight Sensor (OWS), and SRS-ECU / ACM (2021-2024). Part numbers and module variants must be confirmed for your exact year/VIN. Reference part number: 32106850 (2021) - confirm for your exact year/VIN.
Does Polestar 2 (2021-2026) need ADAS calibration after glass or collision work?
The merged generation data documents 15 ADAS systems, including Pilot Assist Forward Camera (Zenseact monocular) (2021), Pilot Assist Forward Radar (Zenseact) (2021), BLIS Radar - Front Corner (L/R) (2021), BLIS Radar - Rear Corner (L/R) (2021), and Park Assist Cameras (360 surround) (2021).

Yes. The generation data includes 10 SRS records, including SRS Airbag Control Module (ACU) (2021), Occupant Weight Sensor (OWS), and SRS-ECU / ACM (2021-2024). 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: 32106850 (2021) - confirm for your exact year/VIN.
Do all Polestar 2 (2021-2026) years use the same parts?
No assumption should be made across the full span. The generation page merges rows across 2021-2026; 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 Polestar 2 (2021-2026)?
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 Polestar 2 (2021-2026) 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.
