Renault Fluence Transmission Oil Pressure Sensor Fault

Transmission warning light on my 2011 Renault Fluence gasoline keeps appearing. Error memory says it's a transmission oil pressure sensor fault. Gearbox sometimes goes into emergency mode, slips, shifts roughly, and makes grinding noises. Could the gearbox oil level be too low, or is it likely the sensor itself?

I experienced similar issues with my Opel Insignia last year. The slipping and rough shifting do sound suspiciously like a transmission issue. Did you check the oil level? Is it okay?

Thanks for the quick reply! No, I haven't checked the oil level yet, as I'm not entirely sure where to find the dipstick or filler plug on this model. Is it easily accessible, or am I going to need to take off half the engine bay to get to it?

On my Insignia it was not easy to access. Given the symptoms and the potential difficulty in checking the oil level, I'd recommend taking it to a workshop for a proper diagnosis. A faulty sensor could also cause these problems, but it's better to be sure.

Thanks, I appreciate the advice! It turned out the oil level was indeed low, and after a top-up and sensor replacement, all is running smoothly now. Cost me about 365€, but worth it for the peace of mind.
