You can try FF on all eprom and cut the immo line. I think is pin 25.

I have the same post with same mcu in Renault Laguna engine.......

I have tried all FFFFF and no worked for me, also have tried both options showed by sogaro, but dont luck.

I think problem is you upload files in .zip format,.......because all bin you have uploaded only contains inside in hexadecimal, the name of the file?????? They are not really all FFFFFFFF .......

Could you please upload it so I can confirm.....or really inside the .bin is the name of the file repeated????

Thanks
