Triggers for ADAS recalibration
Windshield Replacement Affected: Front Camera (mono - standard e-tron; dual - e-tron S), Pre Sense Front, AEB, Active Lane Assist
our diagnostic software static target calibration required. Verify mono vs dual camera setup (standard e-tron vs e-tron S) using our diagnostic software VIN before calibration. Work order first, SVM after pass. OEM glass only. HV safety check before front-end work.
Front Bumper Repair or Replacement Affected: Front Radar ARS510, ACC, AEB, front park sensors
ARS510 static calibration using our diagnostic software. HV cables in front apron - HV de-energization required before bumper removal. Park sensor adaptation if replaced.
HV System Service (BMS / Inverters / OBC / PSS) Affected: J840 BMS, VCU, J741/J742/J743 (e-tron S), OBC, PSS
CRITICAL HV SAFETY: Full HV de-energization (MSD + 5-min discharge) mandatory. our diagnostic software SVM + factory authorization for all HV module replacements. e-tron S tri-motor: J742 AND J743 both require calibration and VCU re-sync after rear inverter service.
Any Collision Affected: J234 SRS, zFAS Gen2, all ADAS sensors, PSS, HV system, all deployed components
CRITICAL: HV system integrity check first. PSS may have fired. Full our diagnostic software scan. J234 likely replace-only. All airbags and pretensioners replaced. ADAS recalibration. SVM on all replaced modules. Do not deliver until HV system safety confirmed.
Any Module Replacement Affected: All our diagnostic software-coded modules
our diagnostic software SVM required. Factory auth for J519, J518, VCU, BMS, inverters, AKL. HV de-energization for HV-connected modules. Verify GE3 (standard e-tron) vs GEA (e-tron S) prefix before ordering any part.
Forward Radar Replacement
Radar module replacement requires alignment/calibration using ODIS-S.
Rear Bumper Repair or Replacement
BSD radar alignment required after rear bumper R&R. Use ODIS-S.
BSM Sensor Replacement
Blind spot monitoring sensor replacement requires calibration using ODIS-S.
Mirror Replacement
If BSD sensor is mirror-integrated, recalibration required. Verify sensor location; use ODIS-S if applicable.

FREQUENTLY ASKED QUESTIONS
FAQ
How much does ADAS calibration cost for a 2021 Audi E-Tron?
ADAS calibration pricing for a 2021 Audi E-Tron depends on which of its 5 documented systems need work after a repair. This vehicle is documented with Pre Sense Front / AEB, Active Lane Assist, Adaptive Cruise Control (ACC), Side Assist / BSD with Exit Warning, and Virtual Exterior Mirrors (optional). We provide a fixed quote after confirming the operations performed - send the VIN, the repair scope (windshield R&R, bumper work, alignment, collision), and any DTCs so the quote response can include a real number.
Can you reset the airbag light on a 2021 Audi E-Tron?
Yes. The 2021 Audi E-Tron uses a factory SRS control module that we support. We read and clear stored crash data, then restore the module to factory status so the airbag warning light goes out and the system returns to full operation. Reference part number on this vehicle: GE3-959-655-X, GEA-959-655-X (E-TRON S). Mobile diagnosis and programming are the active service path. Mail-in bench intake is temporarily unavailable. Send the part number and a description of what triggered the light, and we will provide a quote and scheduling window.
What is needed after replacing the windshield on a 2021 Audi E-Tron?
After windshield replacement on a 2021 Audi E-Tron, Pre Sense Front / AEB and Active Lane Assist rely on the forward-facing camera and require recalibration before the systems return to operation. We perform the calibration on-site in the DFW Metroplex with OE target fixtures. Mail-in intake is temporarily unavailable.
How long does a 2021 Audi E-Tron module service take?
Most 2021 Audi E-Tron onsite jobs are typically scheduled within 24-48 hours once vehicle readiness, access, and route timing are confirmed. This vehicle has roughly 18 programmable modules documented in our database (4 ECU, 4 BCM, 1 TCU, 1 ABS, plus IPC/SAS/gateway/accessory). Mobile module work and ADAS calibration are scheduled in the DFW service area after quote review. Mail-in module intake is temporarily unavailable.
Do you cover the 2021 Audi E-Tron on-site, or is this mail-in only?
We run a mobile unit across the DFW Metroplex for on-vehicle work (ADAS calibration, key programming, IMMO pairing, post-repair recoding, and supported module work). Mail-in module intake is temporarily unavailable. Quote the work and we will confirm the active service path for the 2021 Audi E-Tron. Do not ship a module unless support confirms next steps.
What kind of warranty do you offer on 2021 Audi E-Tron programming?
Every programming, cloning, and calibration job on the 2021 Audi E-Tron is backed by a workmanship warranty covering the scope of work we performed: 1-year unlimited on all flashes, clones, and ADAS calibrations. If a module we programmed or a calibration we performed fails to function as expected, return it and we restore it at no charge. The warranty covers our work; it does not cover unrelated mechanical or electrical failure of the module itself.
Can you program a 2021 Audi E-Tron with no working keys (all-keys-lost)?
Yes - all-keys-lost is supported on the 2021 Audi E-Tron. Immobilizer generation on this platform: Kessy Gen 4 (AES) / ZAS J518 + VCU/BMS BEV authorization. Adding a key (with a working key already in hand) is also supported - typically faster and less expensive than an all-keys-lost reset. Submit the VIN and we will confirm the procedure and quote before scheduling.
Which modules on a 2021 Audi E-Tron can you actually service?
We program, clone, repair, or replace the full programmable-module stack on a 2021 Audi E-Tron. For this vehicle our database documents:
- 4 engine control (ECU/PCM)
- 1 transmission control (TCU/TCM)
- 4 body control (BCM and related)
- 1 ABS / brake control (EBCM)
- 1 immobilizer / security
- 1 key & fob
- 1 instrument cluster (IPC)
- 1 steering angle sensor (SAS)
- 5 ADAS module
Infotainment on this platform: Audi MMI. Send the VIN and the operations performed and we will confirm support and pricing.
Additional Module Part Numbers
Additional OEM-sourced part numbers for the 2021 Audi E-Tron covering ADAS, ECU/PCM, BCM, TCU/TCM, SRS, ABS/EBCM, instrument cluster (IPC), gateway, and steering angle sensor modules when available.
