Immo off Bosch EDC17C42: Renault models
The Bosch EDC17C42 ECU is widely deployed across Renault’s modern diesel vehicles, particularly those using the 1.5, 1.6, 2.0, and 2.3 dCi engines. Common in the Master, Trafic and Clio, this control unit often presents immobilizer-related faults when keys are lost, ECUs are swapped, or the BCM/UCH becomes unsynchronized.
Ourimmo off solution targets the EDC17C42 architecture at firmware level—permanently disabling the immobilizer function in the ECU without affecting vehicle diagnostics or engine mapping. This is not a patch or bypass; it’s a calibrated binary modification compatible with all known Renault implementations of this ECU.
Whether you’re restoring a van to service or building a test bench setup, this file-based service provides a reliable fix without needing emulator hardware or additional coding.
