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

Pre Sense Front is Audi's badging for the collision-avoidance side of the assistance suite. It uses the front radar and forward camera to read the road, and when the dashboard flags Pre Sense Front (or Audi Pre Sense Fault), one or both of those sensors has lost aim or lost calibration.

The common triggers on the A4 (B9) are bumper repair, windscreen swap and any front-end work that touched the radar zone. Pre Sense Rear shares the same family name but covers rear-end protection. Pre Sense Basic handles the seat-belt pretensioner. They share the diagnostic chain but flag separately. Our Pre Sense fault coverage walks through which variant means what and what the fix costs.

Because they share the front sensor pair. The A6 (C8) runs Adaptive Cruise Assist, Active Lane Assist and Pre Sense Front off the same forward radar and the same windscreen-mounted camera. When either drifts out of aim, all three systems read the road wrong and shut down together.

We see this exact pattern from owners: "ACC and Braking guard: unavailable", "Adaptive light fault, Main beam assist fault, Audi pre sense fault", all triggered by a single sensor misalignment. The calibration realigns the radar and camera, and all three systems come back at once. Single job, not three.

Component protection. The Q5 (FY) routes the ACC radar through Audi's security layer, so a brand new radar fitted to the car arrives locked. The dashboard shows ACC Not Available even after the part is bolted on and wired up correctly.

Clearing it needs VAG-compatible tooling with component protection access, followed by the static calibration to aim the radar to spec. We've handled this exact case: "ACC radar parts have been replaced and need calibration and component protection removed." That's one booking with our network: protection cleared, calibration run, certificate issued.

Because Audi's ODIS workshop subscription is a real overhead the dealer passes onto the labour rate. ODIS access runs into thousands per year, and Audi's hourly rate is set high to cover that plus the VAG-network premium positioning.

Our accredited workshops carry VAG-compatible diagnostic equipment and run the same ODIS-spec procedure at network pricing. Same job, same OEM-spec result. The certificate we issue is accepted by insurers and sits on the car's service history. For most Audi calibrations the fixed price is £349, against a dealer quote of £600+.

Often not. A8 (D5) owners we hear from frequently report "Adaptive cruise control currently unavailable" after a battery replacement or a steering sensor fault, both of which can put the ACC system into a calibration-pending state without the radar itself being damaged.

The fix in those cases is a calibration sweep through VAG-compatible tooling: confirm the radar is reading correctly, run the static aim procedure to reset the reference, and clear the fault. No part swap. If the radar itself was damaged in a collision, that's a different scope. Send the registration and a description of what triggered the warning, and we'll quote against the specific scenario.
