ADAS Calibration After Bumper Repair: What to Do Next
Had a bumper repair, and been told your car needs ADAS calibration? The body shop is right, and it isn't an upsell. The radar that runs automatic emergency braking and adaptive cruise sits low in the bumper area, and moving the bumper moves it. Here's why it's needed, what it costs, per system from £162 inc VAT, and whether your insurer should pay.
Bumper work can affect more than one system
A bumper can cover or support radar, parking sensors and cameras, depending on the vehicle. Removal, repair or refitting can trigger checks or calibration under the manufacturer's procedure. It does not mean every sensor moved or that each automatically needs calibration. Include the repair method and any existing findings.
Why the repair details matter
Depending on the vehicle, a bumper can cover or support radar, cameras or parking sensors. Removal, repainting, repair or refitting can trigger model-specific requirements. This does not mean every bumper operation moves every sensor or needs the same calibrations.
Installation condition matters. A distorted bracket, unsuitable repair material, damaged wiring or incompatible replacement can need attention before calibration. A scan supplies fault information, not a measurement of physical movement.
Include rear work as well as front work, and removal for access to a radiator or other component. Reusing the original part does not automatically remove a calibration requirement. A clear dashboard is not proof that the repair procedure is complete.
Which warning has come up?
A bumper repair disturbs different sensors depending on what was done. If a specific warning is showing, go straight to its guide. Driving a Nissan or a Mercedes? Their make guides cover bumper and collision work in depth.

Before you enquire
- 1
Read the exact warning
Follow the warning instructions in your handbook. Photograph the message while safely parked and include any other warnings. Do not rely on an affected assistance feature.
- 2
Describe recent work
Include glass, bumper, suspension, electrical or replacement-part work, and when the warning began. Missing details do not prevent an enquiry.
- 3
Keep earlier findings
Send relevant scan, repair and calibration reports. Do not repeatedly clear codes or test the system by deliberately triggering its warnings.
- 4
Explain practical concerns
Include your location and any unfinished repairs or concerns about driving. Seek qualified advice before travelling if you are unsure whether the car is safe to drive.
Which work may be needed
Send the repairer's findings and describe what was removed, replaced, repaired or painted. A front or rear bumper can involve different radar, camera and parking systems. The manufacturer's repair instructions determine the necessary checks, including work required without a warning.
A diagnostic scan reads available fault information. Its findings, repair instructions and any physical checks guide the next step; further investigation may be needed. The centre pre-scan price is £54 including VAT when that operation is required.
Front-radar calibration is £162 including VAT at a centre. Replacement configuration is a separate operation, listed at £232.80 including VAT. It is not a replacement-and-calibration package, does not supply or fit a part, and is not automatically required again if the installer has already completed it.
The vehicle-specific method can involve static work, a prescribed driving procedure or both. Calibration cannot repair damaged hardware, wiring or an unsuitable installation. The quote covers the work identified for your car; unsuccessful work or a return visit may carry charges.
ADAS calibration prices
A front bumper off usually means one system, the front radar; rear bumper work lands on the blind spot corners and the parking sensors at the back. Rates are the same at every service centre, per system, shown inc VAT with the net figure alongside. Your total is confirmed in writing before anything is booked.
Calibration — per system
Coding a replaced part to your vehicle
- When your job needs a diagnostic pre-scan, it's £54 inc VAT (£45 +VAT), itemised separately. It reads available fault information; finding the cause may require further investigation. A post-scan is a separate operation.
- Two or more systems in one visit: the highest-priced system is full price, each additional system is 35% off at a centre. Scans aren't part of the discount. Front camera and front radar together come to £267.30 inc VAT (£222.75 +VAT).
- Replacement configuration and calibration are different operations. The work required depends on the vehicle and what the installer has already completed. Configuration prices do not include supplying or fitting a replacement part, or an automatic calibration bundle.
- Unsuccessful work, further investigation or a return visit may carry charges, including at a service centre. The appointment terms and written quote set out the work and applicable charges before booking.
- Mobile calibration is available for garages and bodyshops with workshop conditions. Ask us.
Frequently asked questions
Bumper removal or repair can trigger manufacturer-required checks and calibration. The actual vehicle and repair determine which systems need work. Ask for the repair method or recommendation and include it with your enquiry; it is not a universal rule that every bumper operation requires every sensor to be calibrated.
Coverage and authorisation depend on your policy and the agreed repair. Review the repair estimate to see whether calibration is already included before booking it separately. Keep the quote and existing findings for the insurer or repairer; do not assume a new appointment will automatically be reimbursed.
ADAS calibration needs dedicated target equipment, a level calibration bay and manufacturer software, a separate setup from bodywork tools. Most body shops, even good ones, don't have it. Access can be the issue too: on some Nissans the front sensor sits behind the badge and can only be reached once the badge is off, which catches fast-fit garages out. Our Nissan bumper-repair guide covers that. The equipment and the access are the gap our service centres fill.
The centre front-radar calibration rate is £162 including VAT; front camera is £162. Rear radar, parking and surround-view work are different operations. The repair method and findings determine which are needed. Scans, parts and physical repairs are separate, and a scan alone does not prove a sensor was damaged.
It can still be required. A clear dashboard does not prove the manufacturer's post-repair checks or calibration were completed. Include what was removed, repaired, painted or replaced and any result supplied by the repairer.
The appointment length depends on the vehicle, required procedure and condition. Dynamic work can depend on road and weather conditions; faults or unfinished repairs may need attention first. The booking arrangements give the expected timing for your job. Include earlier reports and any time or travel constraints with the enquiry.
Rear work can concern rear radar, cameras or parking equipment, depending on the car. The blind-spot radar calibration rate is £162 including VAT at a centre. The repair procedure determines which operations are required; a scan is not proof of which sensor moved.
Removal and refitting can trigger relevant checks even when the bumper was taken off for access rather than collision damage. The vehicle's repair procedure and actual work determine the requirement. Include whether sensors, cameras, brackets or wiring were disturbed; do not assume that reusing the same parts removes every calibration requirement.
