Hello this is my first post on this forum, I hope somebody will be able to help,

I have a friend that has a 2007 2.0D Volvo S40 and he is unable to start his car because of this c326 ecu communication error. The fix as far as I saw would be an ECU Reload. Can somebody point me in the right direction or provide me with the right file to rewrite the ECU? I have Flash CMD master tool and everything I need in order to rewrite it.

Thank you!
