My GLB DISTRONIC stopped working after the front badge was replaced — why?

The front radar sits directly behind the Mercedes star badge on GLB models. Any badge replacement — even a cosmetic one — can displace the radar housing. A £349 radar calibration restores DISTRONIC function.

Does the GLB seven-seat configuration affect ADAS calibration?

No. The seven-seat variant shares the same ADAS sensor positions as the five-seat GLB. The additional row of seating does not affect any sensor placement or calibration requirements.

After a rear-end collision, my GLB Blind Spot Assist stopped working — what do I need?

Active Blind Spot Assist uses radar sensors in the rear bumper. A rear collision that damages or displaces the bumper will misalign these sensors. A rear sensor calibration (covered under Radar/Sensor Calibration at £349) restores the system.

GLB ADAS Calibration

Mercedes GLB ADAS Calibration

The Mercedes GLB seven-seat compact SUV shares its MFA2 platform with the GLA and uses the same DISTRONIC radar and multifunction windscreen camera combination. Active Brake Assist, DISTRONIC, Active Lane Keeping Assist, and Active Blind Spot Assist are all standard on UK models. As a family vehicle frequently repaired through insurance, windscreen and front bumper calibration is a regular requirement.

ADAS Systems on the Mercedes GLB

The GLB uses Mercedes' MFA2 platform ADAS architecture: a multifunction windscreen camera and front radar working together for DISTRONIC with Speed Limit Assist, Active Brake Assist, Active Lane Keeping Assist, and Active Blind Spot Assist (rear bumper radar). The MBUX infotainment system's camera inputs are separate from the ADAS sensors.

When Does the Mercedes GLB Need ADAS Calibration?

After windscreen replacement - multifunction camera recalibration required.
After front bumper or badge work - front radar realignment required after any removal.
After rear bumper work - Active Blind Spot Assist rear sensors require recalibration.
After a front or rear collision - full sensor check and recalibration on the affected end.
