I am about to drive this Megane and i still have those pesky "Engine warning" messages together with "Battery charging" message.
I fiddled with some connectors inside the protection - relay module under the bonnet and i see if i disconnect CAN connector the car actually reacts to CAN connector removal.

Does anyone have or know about where to get some CAN logs for communication from ECU to Dash control unit?

Tnx

I found another Megane III 1.6 16V year 2010 owner who was kind enough to allow me to record some logs from OBDII port. I recorded from engine still with door open to engine starting and stabilizing at idle and after some seconds i applĨied throttle to spool the engine up. Then i stopped and recorded second file again, engine at idle. Resulting files are here...
For the CSV files i used Savyycan and M2 Macchina device. I didnt have time for more in-depth testing for various inputs, such as throttle or brake inputs.

The other is txt file i made using my own CAN logger.

Feel free to use them, just provide feedback if you find some DBCs
