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

Firefly is a Stellantis-era small-EV brand that uses Mini-derived platform and electronics, which is why the diagnostic toolchain runs through BMW ISTA-compatible equipment rather than the Stellantis stack you'd expect. The Driving Assistant system on the Firefly EV is the same architecture family as a current-generation Mini Cooper, just badged differently.

For calibration purposes that means the workshop needs BMW ISTA-compatible tooling, not the regular Stellantis kit. Our accredited network covers both. Send the registration when you enquire so the workshop confirms the spec and brings the right diagnostic tool to the rig. The procedure follows the BMW-side documented workflow even though the car wears a different badge.

Because the dealer access cost is the overhead, not the calibration itself. Mini dealers run BMW ISTA workshop subscriptions that cost thousands per year, and that overhead sits in the labour rate whether the car they're working on is a Mini Cooper, a current-gen BMW, or a Mini-platform Firefly.

Firefly dealer quotes for ADAS calibration typically land at £500 or higher after inspection. Our accredited workshops carry BMW ISTA-compatible diagnostic equipment, run the same documented Driving Assistant calibration, and price at network rate from £199. The certificate we issue documents the BMW-side procedure followed and sits on the car's service history. Same job, network pricing.

Yes. The Driving Assistant system reads off a forward camera at the top of the windscreen and a radar mounted in the front grille area. Bumper repair or replacement disturbs the radar mounting, and any work to the front of the car can shift the camera's reference angle relative to the road.

The coverage table for the Firefly EV lists bumper repair and windscreen swap as the typical triggers, and both run through the same calibration session on the rig. Driving Assistant won't engage on the test drive until the procedure completes, so the warning either clears or stays lit depending on whether the calibration was actually run. The certificate at the end documents which sensors were realigned and what readings came back.

The calibration procedure for the forward sensors is the same as it would be on a petrol Mini-derived equivalent. Camera at the top of the screen, radar in the grille area, both aimed using target boards on the rig. The EV powertrain doesn't change the sensor architecture.

What the workshop adds for an EV is a 12V battery maintainer during the calibration session. EV calibrations can run 90 minutes to three hours and the 12V auxiliary will drop voltage during a long diagnostic session, which can re-trigger fault codes and force a restart. Our network puts every EV on a maintainer as standard. Procedure runs cleanly, certificate gets issued, system back online same day.

Yes. UK Block Exemption Regulation allows an independent workshop to carry out the calibration without affecting your warranty, provided they follow the manufacturer's documented procedure and use compatible diagnostic equipment. For the Firefly EV that means BMW ISTA-compatible tooling and the documented Mini-derived Driving Assistant procedure.

Our accredited workshops do both. The certificate at the end documents which procedure was followed, what equipment was used and the post-job readings. That record sits on the car's service history as evidence the calibration matches OEM spec, which is what protects you with the dealer network and with insurers if there's a future claim.
