Peugeot 308 oil level sensor fault

I had a similar issue on my 308, although it wasn't a hybrid. Those error messages and the oil pressure light are super annoying, I know. I'd suggest checking the wiring and the plug to the oil level sensor itself. It’s often a simple connection issue. Where did you find the error stored?

Thanks for the tip! Where exactly is the oil level sensor located? And how can I check the error myself?

The oil level sensor is typically located on the oil pan. As for the error, I recommend you go to a workshop. If indeed the cable or the connection is defective, the repair cost shouldn't exceed 95€.

Great, thanks so much for your help! I took it to the shop as you suggested. Turns out it was a dodgy connection to the oil level sensor. They cleaned it up and now it's all good! The bill was pretty much what you predicted. Cheers!
