V70 Oil Level Sensor Issue

That sounds like a pretty common issue with those older Volvos. The oil level sensor is a known culprit. First thing I'd check are the connections to the sensor itself. Look for any corrosion or loose wires. The sensor basically sends a signal to the car's computer (ECU) to tell you the oil level, so if the connection is bad, it'll throw an error. Where is the sensor located on your engine?

Thanks for the quick reply! Where can I find the oil level sensor? I've tried to search for it, but it's unclear where it is exactly. Also, if it is a cable issue, is it easy to check for continuity?

The oil level sensor is usually located on the bottom of the oil pan. As for checking the cable, yes, you can use a multimeter to check continuity. However, if you are not comfortable doing that, I suggest you visit a workshop. It will probably be something like defective cable or plug for this component. The cost should be around 95€. Good luck!

Thanks for the information and location tip! I think I'll bring it to a workshop. I'm not really comfortable with electrical testing, and I don't want to mess anything up. Ended up paying 95€, and it was indeed only a defective cable to the oil sensor.
