Nemo transmission oil sensor fault

I'm having trouble with my 2015 Citroen Nemo gasoline. It has 214946 km. The engine light is on, and I think it's the automatic transmission. The error log says it's the transmission oil temperature sensor. Also, the gearbox sometimes goes into emergency mode, and I feel slippage and rough shifts, with grinding when shifting. Any ideas? I checked for damage, but found nothing.

I had similar issues with my Nemo. Check your gearbox oil level. Low oil was the culprit for me.

Thanks. Can you give me more detail? Did you have the same warning lights and emergency mode? Was the oil level really low when you checked?

Yes, exactly the same symptoms. Warning light, limp mode, rough shifting. I didn't measure exactly how low the oil was, but it was definitely below the minimum mark. A mechanic confirmed the sensor issue was triggered by the low oil.

Thanks for sharing. I took the car to a workshop. The gearbox oil was indeed low, which made the transmission oil temperature sensor fail. After topping up the oil and replacing the sensor, it's fixed. The total repair was 365€. Your help was great.
