Arkana transmission oil temperature sensor error

My 2023 Renault Arkana hybrid is throwing up some odd errors. I'm getting the MIL illuminated, and the error memory points to a faulty transmission oil temperature sensor. Symptoms include the gearbox occasionally going into emergency mode, some slippage, unclean shifts, and even grinding noises at times. Mileage is currently at 102534 km. I've checked for obvious leaks, but nothing jumps out. Has anyone else encountered similar issues with their Arkanas? I'm suspecting a low gearbox oil level, but I'm not certain.

I've had similar issues with my Arkana. The symptoms you described sound eerily familiar to what I experienced a few months back. Did you notice if the problems are more pronounced during longer drives or when the ambient temperature is higher? I am asking because that might point to overheating problems.

Interesting. Yes, the problems do seem worse during longer drives and in warmer weather. Did your error codes also point to the transmission oil temperature sensor? And what was the eventual diagnosis?

Yes, the error codes indicated a faulty transmission oil temperature sensor as well. The workshop confirmed that the gearbox oil level was indeed too low, which likely caused the sensor to malfunction due to overheating, and caused the transmission to enter emergency mode to protect it. I suggest you take it to a workshop to get it checked.

Thanks for the info. Sounds like I'm heading for a similar resolution. I'll book it in at the workshop. For the record, the repair cost was 365€, including the sensor replacement and oil top-up. Hopefully, this will help other Arkana owners in the future.
