I was measuring my backpressure with my OBD and found it sits consistently at 430 hPa. This is an extremely high value to my knowledge, especially since the car feels fine to drive. So I also measured it with the engine completely off. Still 430 hPa, which tells me it's the DPF pressure sensor.

I'm looking to replace it but I'm a bit unsure since there are two sensors for the EU model (N47D20C), the one before and after the DPF with OEM

Which one should I be looking at?

Thanks!
