WHAT WE RESOLVE
B9 (2017-2026) 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 (2017), Active Lane Assist (Spurhalteassistent) (2017), Adaptive Cruise Control (ACC) with Stop & Go (2017), and Blind Spot Detection / Side Assist (2017). Year-marked systems apply only to the shown range.
- SRS crash-data and warning light SRS service can involve Airbag Control Unit (ACU) (2017-2025) and Airbag Control Unit (ACU) (2026). 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 12 merged security records. Access and all-keys-lost support varies by year - verify by VIN.
FREQUENTLY ASKED QUESTIONS
FAQ
Can you program Audi A4 (2017-2026) modules?
Yes. Core Auto Logic supports generation-scoped module programming for the Audi A4 (2017-2026). 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 A4 (2017-2026)?
The Audi A4 (2017-2026) generation currently shows 52 core module records across ECU/PCM, BCM, TCU/TCM, ABS/EBCM, and SRS groups. SRS examples include Airbag Control Unit (ACU) (2017-2025) and Airbag Control Unit (ACU) (2026). Part numbers and module variants must be confirmed for your exact year/VIN.
