WHAT WE RESOLVE
G20/G21 (2019-2026) common module and ADAS issues
- ADAS calibration drift Watch for calibration needs after windshield, bumper, suspension, camera, or radar work. Documented systems include Active Driving Assistant - Frontal Collision Warning / Lane Departure Warning (2019-2023), Forward Radar (77GHz) (2019-2023), Blind Spot Detection (BSD) - Side Radar (2019-2023), and Hands-Free Driving (Highway Assistant) (2019, 2021-2022). Year-marked systems apply only to the shown range.
- SRS crash-data and warning light SRS service can involve Advanced Crash Safety Module (ACSM). 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 25 merged security records. Access and all-keys-lost support varies by year - verify by VIN.
FREQUENTLY ASKED QUESTIONS
FAQ
Can you program BMW 3 Series (2019-2026) modules?
Yes. Core Auto Logic supports generation-scoped module programming for the BMW 3 Series (2019-2026). 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 BMW 3 Series (2019-2026)?
The BMW 3 Series (2019-2026) generation currently shows 30 core module records across ECU/PCM, BCM, TCU/TCM, ABS/EBCM, and SRS groups. SRS examples include Advanced Crash Safety Module (ACSM). Part numbers and module variants must be confirmed for your exact year/VIN. Reference part number: 65.77935000201(A2C37764805) - confirm for your exact year/VIN.
Does BMW 3 Series (2019-2026) need ADAS calibration after glass or collision work?
The merged generation data documents 9 ADAS systems, including Active Driving Assistant - Frontal Collision Warning / Lane Departure Warning (2019-2023), Forward Radar (77GHz) (2019-2023), Blind Spot Detection (BSD) - Side Radar (2019-2023), Hands-Free Driving (Highway Assistant) (2019, 2021-2022), and Hands-Free Highway Assistant (HD Maps) (2023). Calibration triggers include Windshield Replacement (2019-2022), Front Bumper Repair or Replacement (2019-2023), Rear Bumper Repair or Replacement (2019-2023), and DME Replacement (2019-2023). Procedure type is VIN-specific scan-tool procedure; verify exact requirements by VIN before setup.
Can you reset the airbag module on BMW 3 Series (2019-2026)?
Yes. The generation data includes 15 SRS records, including Advanced Crash Safety Module (ACSM). 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: 65.77935000201(A2C37764805) - confirm for your exact year/VIN.
Do all BMW 3 Series (2019-2026) years use the same parts?
No assumption should be made across the full span. The generation page merges rows across 2019-2026; 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 BMW 3 Series (2019-2026)?
Yes, where the VIN and security workflow support it. The generation data includes 25 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 BMW 3 Series (2019-2026)?
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 BMW 3 Series (2019-2026) 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.
