Berlingo radar sensor fault

Radar issues on those older Berlingos are a pain! Is it completely dead, or intermittent? You'll get all sorts of system failures flagged if the radar's chucking a wobbly. Collision avoidance goes offline, traction control might complain... Have you checked the sensor itself for physical damage or if it's caked in muck?

The system seems completely non-functional. How do I check the sensor? I'm not very experienced. Where is it located, and what should I be looking for?

Right, so it's properly dead. The radar sensor is usually behind the front bumper, often near the lower grille. You're looking for a smallish unit, probably plastic. Check the connector is seated properly and isn't corroded. Give the sensor itself a good clean. If that doesn't fix it, it may need recalibration or replacement. Honestly, without proper diagnostic tools, you're better off taking it to a workshop.

I followed your suggestions and located the sensor, cleaned it, and secured the connector. The issue persisted, so I took it to a workshop. They confirmed a faulty sensor connection due to dirt, cleaned the connector, and charged me 45€. Everything is now working.
