Hello everyone, I need help or suggestion, My Clubman S wont start, it crank but did not turn, have a code 2783, 277f, 277b. I put in new plug and ignition coil and still dont start, suggestion will be greatly appreciated. Battery is fairly new reads 12.5v, no sign of issue prior to this problem.

 

When's the last time you had a carbon blast done?

Have you done a compression check?

Those codes seem to be linear with the issues that accompany coked valves.
