GarageNation assesses DPF differential pressure sensor replacement to restore accurate soot load monitoring for compatible Renault Lodgy variants in Hyderabad. Typical estimate: ₹4,000 – ₹14,000; workshop time: 2–4 hours; coverage: 1 year on sensor.
Variant disclaimer: Renault Lodgy has multiple engines and transmissions. This page is not a claim that every variant uses this component; we confirm VIN, engine/transmission data and diagnostic results before approving work.
The model data does not identify a recurring dpf differential pressure sensor fault for every Renault Lodgy. Diagnosis therefore starts with the reported symptoms, fault codes and measured values rather than an assumed model weakness.
Repair is considered where testing confirms a serviceable component and safe parts availability. Replacement is recommended only for confirmed wear, damage or a failed test. A written estimate follows diagnosis; no work starts without approval.
What does the DPF pressure sensor do?
The DPF differential pressure sensor measures exhaust gas pressure before and after the DPF filter. The higher the pressure difference, the more blocked the filter. The ECU uses this reading to decide when to initiate regeneration. A faulty sensor causes either premature regeneration (wasting fuel) or no regeneration despite a full DPF (causing limp mode and DPF damage).
Can blocked DPF pressure sensor pipes be cleaned?
Yes — if the sensor itself is healthy but the small diameter pressure pipes are blocked with soot, GarageNation blows them clear with compressed air. This costs ₹1,500 for the cleaning vs ₹4,000–₹14,000 for a new sensor. We always clear the pipes before condemning the sensor.
