Citroen ADAS Calibration. Prices from £199. Anywhere in the UK.

The forward radar on the C5 Aircross sits behind the lower grille area, and even a minor knock to that part of the bumper shifts the radar's aim enough to take Adaptive Cruise offline. The dashboard message you're seeing is the system flagging that it can't read the road properly, so it disables cruise rather than let it run on bad data.

This is the most common Citroen trigger we see. Owners describe it as the cruise warning popping up after the dealer said the sensor had been hit, often after a windscreen replacement or front-end repair was already done. The fix is a forward radar calibration on the rig. The system comes back the same day, and the workshop issues a certificate showing the post-job alignment readings.

Citroen main dealer quotes for ADAS calibration typically land at £400 or higher after inspection, with the exact figure depending on which systems flagged and how many modules need recoding. Our accredited workshops start from £199 with a fixed quote in hours, not days.

The gap comes down to overhead. Citroen dealers run Stellantis-compatible workshop tooling on a subscription that costs thousands per year, and the labour rate reflects that. Our network carries the same Stellantis-compatible diagnostic equipment, runs the same documented procedure, and prices at network rate. Same job, same OEM-spec result. The certificate we issue is accepted by insurers and goes on the service history.

Sometimes. A wheel alignment on its own doesn't disturb the forward radar or windscreen camera, so most C3s come back from a wheel alignment with the ADAS still in spec. But if the alignment was done after a kerb strike or a bump that also affected the steering geometry, the steering angle sensor can drift, and that does affect lane keeping behaviour.

Several Citroen owners have come to us saying the ADAS warning appeared after wheel alignment. In every case the underlying trigger was the impact that prompted the alignment, not the alignment itself. Send the registration and a quick note on what happened before the alignment, and we'll tell you whether a calibration check is worth booking.

Yes. The ë-C4 runs the same forward camera and radar pair as the petrol C4, plus the Highway Driver Assist module that handles lane centring and traffic-jam assist. Our Stellantis-compatible diagnostic tooling covers all three. Windscreen replacement is the usual trigger because the forward camera lives at the top of the screen and re-aiming it after a new screen is a documented procedure, not optional.

If Highway Driver Assist is the system flagging, that's almost always a camera-side calibration rather than radar. The workshop confirms which sensor needs realigning on the rig and runs only the procedure required. Single calibration session, certificate at the end.

No. A new forward radar is a blank unit until it's coded to the car and calibrated to the road. Until that procedure runs, the radar can sit physically mounted and powered up but the Adaptive Cruise still won't engage, because the car doesn't know the radar's aim or which vehicle profile it's reading.

This is one of the patterns we see most. Owners get the radar swapped after a collision, the dealer or body shop says the car needs calibration to finish the job, and then quote a high follow-up fee. Our workshops complete the coding and calibration as one job on Stellantis-compatible equipment. The certificate documents the part number, post-job readings and which systems came back online.
