Hi,
I know MES is primarily for Citroen/Fiat X250, 290 vans, but as they are almost identical vehicles, does anyone know if the Engine ECU can be read by the latest version of MES? I have V3.9, which was released shortly after the van was registered, and I have not been successful in connecting to the ECU. I have been able to connect to the body computer with the yellow adapter with no issues.
A friend had a 2014 2.0 Citroen Relay, and I had the same trouble connecing to that too. I will update the post with the exact error when I next get a chance to try it.
Thanks.
