V90 Radar Sensor Malfunction

I'm seeing a radar sensor malfunction on my 2016 Volvo V90 gasoline. At 102286 kilometers, I get an error message in the speedometer, an error stored in memory, failures across systems, and a warning light. I've tried some troubleshooting, but no luck. Any ideas?

A 2016 Volvo V90 owner experienced a radar sensor malfunction, indicated by an error message, system failures, and a warning light. The issue was resolved by cleaning the sensor, which was likely obstructed by dirt or grime, and clearing the error memory at a workshop. This solution effectively addressed the problem, restoring the vehicle's systems to normal function.

I had something similar on my V90. Adaptive cruise control went haywire, and the collision avoidance system threw a fit. Did you check if the sensor itself is physically obstructed or dirty? That was my problem.

Thanks. Where is the sensor located, and how do you recommend cleaning or inspecting it?

For me, it was just road grime caked on the front sensor after a long drive. I'd still recommend a workshop visit; they cleared the error memory after I cleaned it. Cost me 45€.

Thanks for the advice. Cleaning the sensor and clearing the error memory at the workshop resolved it, just like you said. Total cost was 45€.
