My dpf backpressure sensor (oem number13627805152) always show pressure 5-25hpa when engine off. I change few sensors (new Hella,two used oem, new oem) and always have same problem. On cold engine measures lower (5-9hpa) and when engine is warm measures always higher (15-25hpa). What I do wrong? Maybe problem is not in sensor?
