Nissan Qashqai 1.5 dCi (EDC17C42) — Reliable DPF & EGR Delete for Cleaner, Stronger Drive

Nissan Qashqai 1.5 dCi DPF & EGR Delete EDC17C42 Tuned File for Pro Workshops

Learn how a precision-calibrated DPF + EGR off tune on the Bosch EDC17C42 ECU unlocks smoother torque, fewer limp-mode surprises, and zero soot-clog headaches on the popular 1.5 dCi Qashqai. Perfect reference for workshop pros looking to deliver warranty-grade results.

Why This Service Matters to Your Workshop

1. Common pain-points solved – The 1.5 dCi’s diesel particulate filter clogs fast on short-trip cars; the EGR valve sticks and triggers fault codes P0401/P0402. A correct software delete ends the cycle of forced regens, DPF swaps, and repeat MIL visits.
2. ECU inside scoop – Bosch EDC17C42 uses Tricore TC1767 with OTP region and RSA signatures. Our file keeps checksum zones intact and recalculates CRC16, so no boot-loop or start refusal after flash.
3. Mapped with purpose – We disable the relevant Soot Mass, Differential Pressure, Post-Injection, and EGR flow tables, set DTC switch-offs (P2402, P2452, P0401, P0402, P042F), and zero out DPF regeneration scheduling while preserving fuel-economy maps.
4. Dyno-verified gains – On stock hardware: +18 Nm mid-range torque, throttle lag cut by ~8 %, exhaust temps drop ≈90 °C under load, safeguarding turbo longevity.
5. Flash-safe workflow – Compatible with K-TAG, Flex, Autotuner, CMDFlash. Read in boot, write in bench or OBD if tool supports RSA unlock. Average write time: 3 min; recovery file supplied.
