Peugeot 108 transmission fault

Hi, I have a 2018 Peugeot 108, gasoline engine, with 257574 km. Recently, the transmission indicator and check engine light came on. The automatic transmission is in emergency mode and doesn't shift smoothly, sometimes slipping or shifting uncleanly. There are also occasional grinding noises. The error code points to a problem with the radiator oil pressure. Could a defective cable or plug connection be the cause?

It's possible. Check the wiring and connections to the oil pressure sensor on the radiator. Are you also experiencing any car overheating issues or noticing any loss of coolant?

I haven't noticed any overheating, and the coolant level seems fine. But where exactly is the oil pressure sensor located? Is it easy to access?

The oil pressure sensor is typically near the oil cooler or on the radiator itself. But if you're unsure and the error code specifically points to the radiator oil pressure, and you have grinding noises, best get it checked by someone with the correct tools.

Thanks for the advice. The workshop confirmed it was indeed a defective cable connection to the oil pressure sensor. Repair cost 95€.
