Vectra radar sensor error

Whoa, sounds like a party of errors! Radar sensor, eh? Is it affecting your collision avoidance? Those sensors are usually pretty well shielded. Maybe a stone got in there somehow? Where exactly is the sensor located on your Vectra?

Yes, it seems to be affecting the collision avoidance system. I believe the sensor is near the front bumper, behind the grille. Could a simple cleaning solve it, or is it more likely a hardware malfunction?

Front bumper, behind the grill, yeah, that's the spot! A good clean could do the trick, but those sensors are sensitive. If it's throwing multiple errors, I reckon it's time to visit a workshop. They'll diagnose it properly.

I took your advice and had the sensor cleaned at a workshop. It was just dirt, as suspected. The repair cost was 45€. Everything is working normally now. I appreciate the help!
