Aygo Transmission Warning Light

Hi, I'm having trouble with my 2006 Toyota Aygo diesel. It's got 107k km on the clock. The transmission warning light keeps popping up, and the error memory shows a faulty transmission oil temperature sensor. When it happens, the gearbox goes into emergency mode, shifts are jerky, and sometimes I even hear a grinding noise. I checked the basics. Any ideas?

Summary of the thread

A 2006 Toyota Aygo diesel owner experienced a transmission warning light, jerky shifts, and grinding noises, with an error indicating a faulty transmission oil temperature sensor. The issue was traced to low transmission oil levels, which can cause sensor malfunctions and trigger emergency mode. The solution involved checking and refilling the transmission oil, which resolved the problem after a visit to a mechanic.

Hey, I had something similar with my Aygo, though I have the petrol engine. Is the gearbox oil level okay? Low oil can cause the sensor to give wacky readings and trigger limp mode. Not sure if it also applies to you but I hope so.

Interesting. I hadn't considered the oil level itself. The grinding noise makes me think it's something more serious. But where exactly do I check the transmission oil level on this thing? Is there a dipstick somewhere?

I don't think there's a dipstick, so it's not that easy to check. Given all the symptoms you describe, it might be better to go to a workshop before you ruin your gearbox. Better be safe than sorry!

Thanks. I appreciate the advice. I took it to a mechanic, and you were right about the oil level. It was very low, causing the sensor issue and everything else. Cost me 365€ to sort out, but at least it's fixed. Thanks again!
