Seat Mii Transmission Problems

My 2019 Seat Mii with a gasoline engine is throwing up some transmission issues at 168997 km. Engine warning light is on and it's stored an error. The gearbox is in emergency mode sometimes, gear shifting is unclean, and I'm hearing grinding noises. Suspect it could be the transmission oil temperature sensor or some oil sensor issue.

Sounds like the transmission issues I had with my Mii. Check the transmission oil temperature sensor. Are you getting any overheating problems?

Overheating problems, you say? How did you figure out it was the temperature sensor? Was it just the MIL?

Yeah, MIL came on, gearbox went into limp mode. Diagnosed as faulty temperature sensor. If the oil level is low, that can cause overheating and trigger the sensor. Get it checked ASAP.

Appreciate the insight. Turns out the gearbox oil level was indeed low. Cost me 365€ to get sorted.
