Seat Formentor transmission fault

My Seat Formentor (2023, diesel) is throwing up some weird symptoms at 97442 km. Transmission indicator and check engine light are on. The automatic gearbox is in emergency mode, shifts poorly, slips, and makes grinding noises. Error memory mentions radiator oil pressure. Suspect a defective cable or plug connection. Any ideas?

That does sound like a faulty sensor. I would start by checking the wiring and connections to the pressure sensor on the oil cooler. A leak detection test on the cooling system and a pressure gauge test might also help to pinpoint the issue. Is the coolant level stable? Keep an eye on it.

Where exactly is the pressure sensor located? Is it easy enough to get to?

The pressure sensor is usually located on the oil cooler itself or nearby, part of the cooling system. It should be accessible, but depending on the engine layout, some components might need to be moved for clear access. Considering the symptoms and error code, plus the fact that you mentioned grinding noises, it is safer to have a workshop take a look.

Cheers for the help. Ended up being a dodgy connection to the pressure sensor like you said. 95€ to fix it.
