I have a Renault Megane RS III, version euro 6 ECU EMS3125.
unfortunately, I can't find the wiring diagram + pinout for this version anywhere.


VIN: VF1DZ1X0H53820393


in any program (alldata, autodata, haynes pro, renault visu, renault dialogys, asot, etc etc) only the EMS3110 scheme / Euro 5 ECU version is displayed. I directly compared several sensors, MAP for example and the wiring does not match.


.... as this version (euro 6) was produced for a relatively short time, is it possible that Renault has not entered the relative data in the program for several months? at the local Renault dealer, on the Renault online server it seems that only the old EMS3110 is present....)


as a direct comparison, MAP sensor:


EMS3110 / CONNECTOR A


1. D2
2. D3
3. B3






EMS3125 / CONNECTOR A


1. D1
2. J1
3. E4


EMS3125 comes with native (5 wire) wideband, which also distinguishes "fast" EMS3110 from 3125, etc.


Does anyone know where I can find this diagram please?
