Nissan Sunny DPF Chemical Cleaning in Hyderabad | GarageNation

GarageNation assesses off-vehicle DPF soaking with specialised chemical solution to remove ash and soot from blocked diesel particulate filter for compatible Nissan Sunny variants in Hyderabad. Typical estimate: ₹12,000 – ₹35,000; workshop time: 2–3 days; coverage: 6 months on cleaning.

Variant disclaimer: Nissan Sunny 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.

Nissan Sunny Variants We Check

• 1.5 HR15 petrol (99 bhp)
• 1.5 K9K diesel (86 bhp)

Symptoms That Merit a Check

• DPF above 85% soot load — forced regeneration not resolving the blockage
• DPF differential pressure above 150 mbar at idle — severe restriction
• Multiple forced regeneration cycles failing to reduce soot load
• DPF physically removed showing solid carbon plug blocking filter channels
• DPF ash accumulation beyond 80g — requires physical cleaning not thermal regeneration

Diagnostic Process

• DPF soot load and ash load reading via OEM tool — ash load above 80g requires physical cleaning
• DPF differential pressure test confirms severity of blockage
• DPF removal for visual inspection and weight measurement (soot increases DPF weight)
• Chemical soak in specialised DPF cleaning fluid for 12–24 hours, then compressed air purge and dry

Model Context and Repair Decision

The model data does not identify a recurring dpf chemical cleaning fault for every Nissan Sunny. 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.
