FREQUENTLY ASKED QUESTIONS

FAQ

How much does ADAS calibration cost for a 2021 Audi A6?

ADAS calibration pricing for a 2021 Audi A6 depends on which of its 5 documented systems need work after a repair. This vehicle is documented with Pre Sense Front / AEB (zFAS Gen2 - dual camera), AI Traffic Jam Assist Level 2, Adaptive Cruise Control (ACC) with Predictive Efficiency Assist, Side Assist / BSD with Exit Warning, and 360-Degree Surround View (Mirror-Integrated Side Cameras). 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 and we return a number within 4 hours.

Can you reset the airbag light on a 2021 Audi A6?

Yes. The 2021 Audi A6 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: 4G0959655A. Bench-only or in-vehicle - both paths are supported. Send the part number and a description of what triggered the light, and we will provide a quote and ETA.

What is needed after replacing the windshield on a 2021 Audi A6?

After windshield replacement on a 2021 Audi A6, Pre Sense Front / AEB (zFAS Gen2 - dual camera) and 360-Degree Surround View (Mirror-Integrated Side Cameras) rely on the forward-facing camera and require recalibration before the systems return to operation. We perform the calibration on-site (DFW Metroplex) with OE target fixtures or via mail-in for the front camera/radar module.

How long does a 2021 Audi A6 module service take?

Most 2021 Audi A6 jobs complete same-day once the vehicle or module arrives. This vehicle has roughly 20 programmable modules documented in our database (3 ECU, 3 BCM, 3 TCU, 1 ABS, plus IPC/SAS/gateway/accessory). Module-bench work (ECU clones, BCM reprograms, SRS resets) ships back inside 1-3 business days including return shipping. ADAS calibration is on-site for DFW or mail-in for the front module.

Do you cover the 2021 Audi A6 on-site, or is this mail-in only?

Both. We run a mobile unit across the DFW Metroplex for on-vehicle work (ADAS calibration, key programming, IMMO pairing, post-repair recoding) and a mail-in bench for module-only jobs (ECU cloning, BCM repair, SRS reset, TCU clone). Quote the work and we will tell you which path is right for the 2021 Audi A6.

What kind of warranty do you offer on 2021 Audi A6 programming?

Every programming, cloning, and calibration job on the 2021 Audi A6 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 A6 with no working keys (all-keys-lost)?

Yes - all-keys-lost is supported on the 2021 Audi A6. Immobilizer generation on this platform: Kessy Gen 4 (AES) / ZAS J518. 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 A6 can you actually service?

We program, clone, repair, or replace the full programmable-module stack on a 2021 Audi A6. For this vehicle our database documents:

  • 3 engine control (ECU/PCM)
  • 3 transmission control (TCU/TCM)
  • 3 body control (BCM and related)
  • 1 ABS / brake control (EBCM)
  • 1 immobilizer / security
  • 1 key & fob
  • 2 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.
