We are on board our Mercedes C-Class W203 version: we can't get it started in any way, the temperature doesn't rise and we can't move any components. But we don't lose heart.

We have a solution that will temporarily solve the situation, allowing us to at least reach the nearest mechanic; we open the fuse box, and we restart the starter relay contact. Of course, this is only a temporary solution, the solution is to replace the ECU, but at least we have started and we can reach our mechanic and talk to him about the problem.
