DPF sensor – Volvo V50 2.0D 2006

Hello,

Recently, the engine light, emergency mode, codes P2452, P2453 (Pressure sensor particulate trap Faulty signal). I had the sensor replaced, reset on the diagnostics (Vida in Volvo). The car drove normally and after a week the problem returned. The sensor was replaced again, again in a week and the same problem. Why does this sensor always die? Almost no soot inside.

CAR: VOLVO V50 2.0D 100kw

If anyone can advise me, I will be grateful.

Thank you.

Brand: Volvo
Model: V50
Year: 2006
