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

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 any disturbance to the badge area shifts the radar aim. We've taken multiple A-Class owners with this exact dashboard text. One owner had fault code C10C700 (front radar sensor maladjusted) with a B220600 VIN coding fault, and the front grille badge was suspected to be aftermarket.

The radar is unforgiving about badge geometry. A genuine Mercedes badge sits flush with the radar's expected aim point. An aftermarket badge or a slightly misseated repair badge shifts the radar by a fraction of a degree, which the system reads as a maladjustment fault. Our Distronic fault coverage walks through this in detail. The fix is the XENTRY-compatible calibration with VIN coding where required, and our accredited workshops carry both.

No, the calibration on its own won't affect your warranty. We had an exact A-Class W177 case recently where a Mercedes master technician fitted the front camera and communicated with it via XENTRY, and the car only needed the final calibration step run.

Under the Block Exemption Regulation, an independent workshop can run the XENTRY-compatible calibration without affecting your Mercedes warranty, provided the procedure is followed correctly and the equipment is compatible. Our accredited workshops carry XENTRY-compatible tooling and will pick up the procedure from wherever the previous technician left it. The certificate we issue documents what was done, which sits on the car's service history alongside the master technician's record of the camera fit.

A single Distronic fault is usually a forward-radar realignment after a bumper repair or parking knock. One sensor, one procedure, one visit. The full collision repair recalibration is different: after a body shop returns the car with multiple panels replaced, DISTRONIC, Active Brake Assist, Blind Spot Assist, Pre-Safe and the multifunction camera typically all need clearing together.

Our collision-repair recalibration is £499 fixed for the multi-module job. The single-radar Distronic case runs at £349 fixed. The way to tell which one applies: if your Mercedes has come back from a body shop with multiple ADAS warnings on the dash at once, it's the collision repair procedure. If only Distronic and Active Brake Assist are flagging, it's the single-radar calibration.

Because the rear-quarter radars that feed Blind Spot Assist on the GLC sit either side of the rear bumper, on brackets that flex during any rear-end work. After bumper removal or a side-impact repair, both radars typically lose alignment together, which is why Active Lane Change Assist usually drops out at the same time.

Our Blind Spot Assist coverage walks through this in detail. The job is the rear-quarter calibration procedure run with XENTRY-compatible equipment, fixed at £349 for the standard A-Class, C-Class, GLC and E-Class scope. On the GLE V167, the towbar wiring trigger we list often appears alongside Blind Spot Assist faults because tow loom installation routes through the same rear-quarter area. Our accredited workshops handle both in the same visit when they appear together.
