WHAT WE RESOLVE

GE (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 Pre Sense Front / AEB (e-tron variant) (2019), Active Lane Assist (2019), Adaptive Cruise Control (ACC) with Stop & Go (2019), and Side Assist / BSD with Exit Warning (2019). Year-marked systems apply only to the shown range.
SRS crash-data and warning light SRS service can involve Airbag Control Unit (ACU) (2019), HV Contactor Safety Relay (Pyrotechnic Safety Switch - PSS) (2019), and Occupant Detection System (ODS - J706). 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 15 merged security records. Access and all-keys-lost support varies by year - verify by VIN.

FREQUENTLY ASKED QUESTIONS

FAQ

Can you program Audi e-tron (2019-2026) modules?

Yes. Core Auto Logic supports generation-scoped module programming for the Audi e-tron (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 Audi e-tron (2019-2026)?

The Audi e-tron (2019-2026) generation currently shows 75 core module records across ECU/PCM, BCM, TCU/TCM, ABS/EBCM, and SRS groups. SRS examples include Airbag Control Unit (ACU) (2019), HV Contactor Safety Relay (Pyrotechnic Safety Switch - PSS) (2019), and Occupant Detection System (ODS - J706). Part numbers and module variants must be confirmed for your exact year/VIN. Reference part number: GE3-959-655-X (2019) - confirm for your exact year/VIN.

Does Audi e-tron (2019-2026) need ADAS calibration after glass or collision work?

The merged generation data documents 29 ADAS systems, including Pre Sense Front / AEB (e-tron variant) (2019), Active Lane Assist (2019), Adaptive Cruise Control (ACC) with Stop & Go (2019), Side Assist / BSD with Exit Warning (2019), and Virtual Exterior Mirrors (optional - camera-based side mirrors) (2019). Calibration triggers include Windshield Replacement (2019), Front Bumper Repair or Replacement (2019), Rear Bumper Repair or Replacement (2019), and HV Battery Service (BMS / Cell Replacement / Battery Pack Replacement) (2019). Procedure type is VIN-specific scan-tool procedure; verify exact requirements by VIN before setup.

Can you reset the airbag module on Audi e-tron (2019-2026)?

Yes. The generation data includes 19 SRS records, including Airbag Control Unit (ACU) (2019), HV Contactor Safety Relay (Pyrotechnic Safety Switch - PSS) (2019), and Occupant Detection System (ODS - J706). 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: GE3-959-655-X (2019) - confirm for your exact year/VIN.

Do all Audi e-tron (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 Audi e-tron (2019-2026)?

Yes, where the VIN and security workflow support it. The generation data includes 15 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 Audi e-tron (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 Audi e-tron (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.
