DPF Temperature Sensor refers to DPF upstream and downstream temperature sensor replacement for accurate regeneration cycle control. GarageNation handles this specific repair daily — it is one of the most frequently misdiagnosed issues in Hyderabad workshops that lack OEM-level scan tool access and component-level expertise.
Based on GarageNation's Hyderabad workshop experience, DPF Temperature Sensor issues are most frequently seen on: BMW, Volkswagen, Maruti, Ford. However, we perform this repair on all car brands sold in India.
DPF Temperature Sensor repair at GarageNation: ₹4,000 – ₹12,000. Turnaround time: 1–3 hours. Warranty: 1 year on sensor. We provide a written repair estimate before any work begins — no surprise charges.
Why does my car have two DPF temperature sensors?
The two DPF temperature sensors measure exhaust gas temperature before the DPF (upstream) and after (downstream). The temperature rise across the DPF during active regeneration (DPF acts as a furnace) is used to calculate regeneration efficiency. BMW and VW diesel cars with DPF use both sensors for precise regeneration control.
Will a faulty DPF temperature sensor damage the engine?
A sensor that reads too low tricks the ECU into adding more fuel for regeneration, which can overheat the DPF and cause cracking. A sensor reading too high prevents the ECU from raising temperatures enough to complete regeneration, filling the DPF with soot. Both failure modes are harmful over time — GarageNation replaces DPF temperature sensors only after confirming the fault with a resistance test.
