DME - B48B20 2.0L (330i) Verify by VIN 2019-2023 12146-8652015
Documented for 2019-2023 within this generation. Confirm the exact vehicle by VIN.
Coverage and replacement notes
Documented years: 2019, 2020, 2021, 2022, 2023
Year coverage is not proof of interchangeability. Confirm the full part number and vehicle configuration before buying a used module.
Access
Located: Engine bay, in the electronics box (E-box) at the rear of the engine compartment on the passenger side, below the cowl/microfilter housing. Unit is the Bosch MG1-family ECU used with B46/B48 four-cylinder and B58 six-cylinder engines.
Open the hood, clear the cowl/microfilter cover area, and open the E-box lid at the rear of the engine bay. The DME sits in the E-box with a multi-pin connector and a retaining clip. Battery disconnect is standard practice before unplugging.
Connector notes: Single large multi-pin DME connector with a locking lever. MG1 generation control unit.
Disconnect the battery first.
Bench pinouts are documented for this unit.

- ISTA SDP flash required. ISN (Individual Serial Number) in DME must match CAS/FEM/BDC - ISN adaptation is mandatory after DME replacement. Specialist ISN tools (AUTEL IM608 Pro, Autologic, or BMW ISTA with dealer auth) required to read/write ISN. Battery must be at sufficient charge before SDP flash. Do not interrupt flash - EtherBoot on BDC-equipped builds. Aftermarket DME requires ISN adaptation or vehicle will not start.

Access
Located: Front passenger footwell area, behind the kick panel / under the carpet near the A-pillar base. On the G20 the BDC is the central body computer and is a known water-ingress failure point because of this low footwell location.
Remove the passenger-side lower trim / kick panel and pull back the footwell carpet to reach the BDC. It carries several connectors. The unit is bolted/clipped in place.
Connector notes: Multiple wiring-harness connectors; the BDC also serves the integrated central-gateway function on this platform.

Located: Under the center console on the transmission tunnel floor, between the two front seats (center of the cabin floor). Mounted to the floor with three nuts.
Lift/remove the center console to expose the module on the floor tunnel. It is held by three 10mm nuts and has a keyed connector. Seats often need to be slid back or out for working room. Battery must be disconnected before any work on this unit.
Connector notes: Keyed/locking SRS connector (green plug noted in service writeups). Three mounting nuts.
Disconnect the battery first and wait 1 minutes for capacitors to discharge.
Verify before relying on this - secondary sources only.
Airbag system components - professional service is strongly recommended. Never probe or handle an SRS module with the battery connected.

Triggers for ADAS recalibration
Windshield Replacement 2019-2022 Affected: KAFAS 3 Camera, Lane Departure Warning, Frontal Collision Warning, Active Cruise Control
KAFAS 3 mono camera requires static target calibration followed by dynamic road drive via ISTA. Use only OEM-approved windshield glass - non-OEM glass may cause calibration failure due to rake angle or tint variance. Reinstall camera bracket precisely per ISTA mounting spec.
Front Bumper Repair or Replacement 2019-2023 Affected: FRSF Front Radar, Adaptive Cruise Control, Pre-Collision
ISTA static radar alignment required after front bumper work. Vehicle at curb weight on level surface. Inspect radar mounting bracket for deformation. FRSF radar aim out-of-tolerance triggers DTC 48A0 and disables ACC.

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.
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 modules 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.
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 service is available nationwide. Exact service eligibility is confirmed from the year, VIN, module, and requested scope.
Is BMW 3 Series (2019-2026) 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.
