An oil cooler integrated with the radiator coolant system? I'm not sure, to be honest. Where would I check for that? And would a faulty sensor really cause all those problems?

Yeah, on the Volvo, the sensor was sending incorrect readings to the transmission control unit, putting it into limp mode. Check where the oil filter is located, the oil cooler might be nearby, connected to the radiator with hoses. But honestly, with those symptoms and that error code, I would get it checked by someone who knows what they're doing before you cause further damage.

Took it to the local garage, and you were spot on! Faulty connection to the pressure sensor on the oil cooler. They cleaned it up and replaced a dodgy connector. Cost me 95€. That's a lot better than a new gearbox! Thanks for the help!

Sounds familiar. I had similar symptoms on my old Volvo a while back. Turned out to be a faulty pressure sensor on the oil cooler, causing the gearbox to freak out. Does your Ateca have an oil cooler integrated with the radiator coolant system?
