Renolink — Renault ECU Reset & Programming Tool

ecufiles.io file service — compatible with all major tuning tools

Renolink is a Renault/Dacia-specific OBD programming tool primarily used for UCH (central multiplex unit) pairing, airbag reset, and immobiliser programming. It also supports ECU flashing on select Renault platforms, making it useful for workshops that specialize in Renault and Dacia vehicles.

Renolink connects via OBD and uses Renault's proprietary diagnostic protocols. While its primary function is body electronics rather than performance tuning, it can be used to write calibration files on supported ECUs — particularly older Siemens and Delphi diesel units — after they have been read by a dedicated tuning tool.

Protocols Supported
  • Renault OBD proprietary (CAN and K-Line)
  • UCH/BSI pairing protocol
  • Renault immobiliser (IMMO) protocol
Compatible ECUs
  • Siemens SID301 / SID305 (older Renault diesel)
  • Delphi DCM1.2 / DCM3.2 (Renault 1.5 dCi pre-2007)
  • Renault Bosch ME7.4.6 (petrol Clio/Megane)
⚠ Renolink is not a general-purpose ECU tuning tool. For SID807/DCM6.2 work, use KESS3 or PCMFlash instead.
