ADAS calibration pricing for a 2021 Mercedes Benz GLS depends on which of its 6 documented systems need work after a repair. This vehicle is documented with Front Multi-Mode Camera (Driver Assistance Package Plus), Front Long-Range Radar (Distronic Plus / ABA 5), Blind Spot Assist Plus / Rear Cross-Traffic Alert, Active Parking Assist / Parktronic, and 360-Degree Camera System. 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.
Yes. The 2021 Mercedes Benz GLS 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: A2229004712. Mobile diagnosis and programming are available in DFW, and mail-in module service is available nationwide. Send the part number and a description of what triggered the light, and we will provide a quote and scheduling window.
After windshield replacement on a 2021 Mercedes Benz GLS, Front Multi-Mode Camera (Driver Assistance Package Plus) and 360-Degree Camera System 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 module service is available nationwide for eligible module work.
Most 2021 Mercedes Benz GLS onsite jobs are typically scheduled within 24-48 hours once vehicle readiness, access, and route timing are confirmed. This vehicle has roughly 17 programmable modules documented in our database (4 ECU, 3 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 service is available nationwide.
We run a mobile unit across the DFW Metroplex for on-vehicle work (ADAS calibration, post-repair recoding, and supported module work). Mail-in module service is available nationwide. Quote the work and we will confirm the active service path for the 2021 Mercedes Benz GLS. Do not ship a module unless support confirms next steps.
Every programming, cloning, and calibration job on the 2021 Mercedes Benz GLS 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.
We program, clone, repair, or replace the full programmable-module stack on a 2021 Mercedes Benz GLS. For this vehicle our database documents:
