FREQUENTLY ASKED QUESTIONS

FAQ

How much does ADAS calibration cost for a 2019 Audi A4?

ADAS calibration pricing for a 2019 Audi A4 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) with Stop & Go, Blind Spot Detection / Side Assist, and Park Distance Control (PDC). 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 2019 Audi A4?

Yes. The 2019 Audi A4 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: 8W0-959-655. 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 2019 Audi A4?

After windshield replacement on a 2019 Audi A4, 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 (DFW Metroplex) with OE target fixtures or via mail-in for the front camera/radar module.

How long does a 2019 Audi A4 module service take?

Most 2019 Audi A4 jobs complete same-day once the vehicle or module arrives. This vehicle has roughly 20 programmable modules documented in our database (3 ECU, 2 BCM, 4 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 2019 Audi A4 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 2019 Audi A4.

What kind of warranty do you offer on 2019 Audi A4 programming?

Every programming, cloning, and calibration job on the 2019 Audi A4 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 2019 Audi A4 with no working keys (all-keys-lost)?

Yes - all-keys-lost is supported on the 2019 Audi A4. 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 2019 Audi A4 can you actually service?

We program, clone, repair, or replace the full programmable-module stack on a 2019 Audi A4. For this vehicle our database documents:

  • 3 engine control (ECU/PCM)
  • 4 transmission control (TCU/TCM)
  • 2 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

Send the VIN and the operations performed and we will confirm support and pricing.

Different trim or build?

Send your VIN and we'll confirm exact module support and pricing for your specific vehicle within 4 hours.
