Vauxhall Insignia P2453 fixed…. This Vauxhall Insignia came into our HQ Energy Tuning with a DPF problem and fault code P2453 stored. We quickly diagnosed that the DPF pressure was too high and also that the DPF pressure sensor was reading incorrect data. We replaced the sensor and carried out our 3 stage DPF clean to have the car quickly back on the road.
