XC70 Oil Level Sensor Faulty

I'm getting an "Oil level sensor faulty" error on my 2016 Volvo XC70 gasoline. It's stored in the system memory, the warning light is on, and the oil pressure lamp flickers sometimes. I'm thinking it's a bad cable or plug. Any advice?

I had something similar with my XC70. The oil level sensor acted up now and then. Have you checked the sensor for damage or corrosion? Did you recently change the oil or do any maintenance that might have messed with the wiring?

Thanks. I don't see any damage to the sensor or corrosion around the plug. I changed the oil about 5000 km ago. Is there a specific wiring area I should check?

I couldn't find the exact wiring spot, but the symptoms sound the same. Because the warning kept coming back, I took it to a shop. They found a bad connection, cleaned it, and the error went away. Given the risk of engine damage, I'd suggest doing the same.

Okay, thanks. I'll book an appointment with a workshop. They quoted around 95€ to diagnose and fix or replace the connection. Hopefully, that fixes it.
