Hyundai/Kia DPF Delete - EDC17C57, EDC17CP62 - Tucson, Sportage, i30

Hyundai/Kia Diesel DPF Overview

Hyundai and Kia share diesel engine platforms across their vehicle ranges. The popular 1.6 CRDi and 2.0 CRDi engines use Bosch EDC17 ECU variants and are equipped with DPF systems that experience many of the same issues seen in European competitors.

ECU and Vehicle Coverage

• EDC17C57 - Hyundai Tucson 1.6/2.0 CRDi (TL, 2015+), Hyundai i30 1.6 CRDi (GD/PD), Kia Sportage 1.6/2.0 CRDi (QL, 2016+), Kia Ceed 1.6 CRDi (JD/CD)
• EDC17CP62 - Hyundai Santa Fe 2.2 CRDi (TM, 2018+), Kia Sorento 2.2 CRDi (UM, 2015+), Hyundai Tucson 2.0 CRDi (NX4, 2021+)

DPF Issues on Hyundai/Kia Vehicles

The 1.6 CRDi engine is particularly affected by DPF problems due to its relatively low exhaust temperatures and high soot output. Many Tucson and Sportage owners report DPF warnings as early as 40,000 km, especially in urban driving conditions. The 2.2 CRDi in the Santa Fe and Sorento fares better but still develops issues in heavy-use scenarios.

DPF Delete Process

• ECU read via OBD protocol (both variants support OBD read/write)
• DPF regeneration and monitoring strategy disabled
• Pressure differential sensor logic removed
• Temperature monitoring adjusted
• All DPF-related fault codes cleared

Benefits

Hyundai and Kia owners experience improved fuel economy (8-15%), smoother driving without regeneration interruptions, elimination of the DPF warning that can trigger limp mode, and significant savings versus DPF replacement (which can cost 1,200+ EUR on these models).
