Peugeot 5008 Transmission Oil Pressure Sensor Fault

I have a 2009 Peugeot 5008 with a gasoline engine and only 22878 km. Lately, the engine warning light comes on, and the error memory mentions a transmission oil pressure sensor fault. The gearbox goes into emergency mode, slips, shifts uncleanly, and makes grinding noises. Could the gearbox oil level be too low? Has anyone experienced similar issues?

Interesting. I have a 5008 too, and had similar symptoms a while back. Did you check the transmission fluid level? What happens if you reset the error?

I haven't checked the fluid level yet, but resetting the error only helps for a short while. The light comes back on pretty quickly. Was it definitely the oil level in your case?

Well, it was a very similar problem. Considering your symptoms, it might be safer to get it checked by a workshop. It could be other things, but low oil is a common one. Why risk making it worse?

Thanks for the insight! I had the oil level checked, and indeed it was too low. After topping it up and replacing the sensor, the issue is now resolved. The bill came to 365€.
