Calibration and certificate
The centre runs the manufacturer-spec calibration and issues your certificate on completion. Any diagnostic scan the job needs is itemised on the quote, never folded in silently.
Mercedes calibration prices
Network rates, the same at every service centre, whichever Mercedes is on the ramp. Every price is per system, shown inc VAT with the net figure alongside. Your total is confirmed in writing before anything is booked.
Calibration — per system
After a part was replaced (includes coding to your vehicle)
- When your job needs a diagnostic scan, it's £54 inc VAT (£45 +VAT), always itemised as its own line. It shows which systems were live before work started.
- 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).
- On mobile trade visits only: if the technician attends and the calibration can't be completed, a sensor fitted misaligned for example, a call-out fee of up to £72 inc VAT (£60 +VAT) applies.
- Mobile calibration is available for garages and bodyshops with workshop conditions. Ask us.

Frequently asked questions
Yes for any Mercedes carrying Distronic, Active Brake Assist, PRE-SAFE or Active Lane Keeping. Our coverage table above lists the A-Class W177, C-Class W206, E-Class W214, GLC X254, GLE V167, S-Class W223, EQA, EQB, EQS, Sprinter W907 and V-Class W447 with their typical triggers.
The Sprinter and V-Class are commercial vehicles that occasionally surprise owners with how much ADAS they carry, and the EQ range adds extra modules that fault together after front-end work. If your Mercedes isn't on the list above, send the registration with your enquiry and we'll confirm the specification before booking.
Because the forward radar that feeds Active Brake Assist on the A-Class sits behind the front star badge, and front-end work that disturbs the radar's mounting shifts its aim. A typical case looks like this: front-end work, the badge comes off and goes back on, and 'Active Brake Assist function limited' appears within the first few drives. The codes that come with it are usually C10C700, front radar sensor maladjusted, sometimes with a B220600 coding fault alongside. If the warning keeps returning after front-end work, the diagnostic scan confirms whether the radar module itself is failing, a known pattern on some earlier cars, before any calibration is booked.
The badge itself matters differently: it sits in the radar's signal path, and an aftermarket or misseated badge can weaken or scatter the beam enough to trip the fault, interference rather than misalignment. Our Distronic fault page walks through this in detail. The fix is a front radar calibration to Mercedes' documented procedure, £162 inc VAT (£135 +VAT) at a centre, and where a coding fault sits alongside, the centre prices that as its own line. Your quote is confirmed in writing before anything is booked.
No. Under the UK Block Exemption rules, an independent workshop can run the calibration without affecting your Mercedes warranty, provided the manufacturer's documented procedure is followed correctly. Calibration runs to full manufacturer specification at our service centres, so the final aim step can be picked up where the fitting technician left off.
The handover case is common: a camera or radar gets fitted, sometimes by a dealer technician, and the calibration is the one step still outstanding. Tell us what was fitted and who fitted it when you enquire, and the centre confirms the procedure for your car. Calibration after a camera replacement is £229.20 inc VAT (£191 +VAT) at a centre. The certificate records the post-job readings against Mercedes' tolerances, the same standard a dealer issues, and sits on the car's service history alongside the record of the camera fit.
A single Distronic fault is usually one system: the front radar loses its aim after a bumper repair or a parking knock, and one calibration puts it right. Collision repair is wider. When a body shop returns a car with several panels replaced, Distronic, Active Brake Assist, Blind Spot Assist and the multifunction camera can all need calibrating in the same visit, because each disturbed sensor holds its own aim reference. PRE-SAFE comes back once the radars it leans on read straight.
The pricing follows the systems, not a package name. A single Distronic fault is one line, front radar calibration at £162 inc VAT (£135 +VAT), and a collision case adds a line for each disturbed sensor, so the quote reflects what the repair actually touched. Two or more systems in one visit: the highest-priced system is full price and each additional system is 35% off at a centre.
The radars that feed Blind Spot Assist sit in the rear bumper corners, on brackets that flex during any rear-end work. Bumper off for a repair, a parking knock on a rear quarter, a light shunt that never cracked the paint: any of them can push a radar past its tolerance, and the dash shows 'Blind Spot Assist inoperative'. Active Lane Change Assist often drops at the same time because it reads the same radars.
The job is a blind spot radar calibration at £162 inc VAT (£135 +VAT) at a centre. On the GLE, towbar wiring routes through the same rear-quarter area, which is why our coverage table lists it as a trigger; if the fault arrived with a towbar fit, say so when you enquire so the centre knows what it's walking into.
Dealer quotes customers have shown us for ADAS work run £300 to £900, usually put together after an inspection with the car already on site. A franchise workshop reaches its figure through an hourly labour rate, and a Mercedes badge sets that rate high. The calibration itself is the same documented procedure wherever it runs.
Front camera calibration is £162 inc VAT (£135 +VAT), front radar is the same, with the full rate card on this page. Two or more systems in one visit: the highest-priced system is full price and each additional system is 35% off at a centre. Certificate to manufacturer tolerances, the same standard dealers issue.
