Skoda Fabia Transmission Issues

Sounds like a faulty radiator coolant pressure sensor. The transmission indicator light and check engine light coming on together, along with the emergency mode, are common symptoms. The grinding noises when shifting could be related to the transmission not receiving the correct data from the sensor, causing it to shift improperly. Have you checked the cable and plug connection to the sensor itself? A loose or corroded connection can cause these issues. Is there any sign of a coolant leak near the radiator or the sensor?

I visually inspected the cable and plug, but couldn't see anything obvious. Where exactly is the pressure sensor located? And what should I be looking for in terms of corrosion or damage?

Yeah, a dodgy connection is the most likely culprit, especially with those symptoms and error code. It's a common problem on older cars. Given the age, the sensor itself might be failing. It's probably best to get it checked by a workshop; they can properly diagnose the wiring and sensor. Ignoring it could cause more damage to the automatic transmission if it is in emergency mode.

Thanks for the input! Turns out it was a defective cable to the pressure sensor, just like you suspected. Cost me 95€ to get it sorted. All good now!
