Hi all,

We have a C Max 2005 diesel.

On a trip to Wales the car just cut off while driving and would not restart. When you turn the key nothing happens, no lights on the dash or anything else.

Towed the car home and here are my findings:
  • Central locking works off the remote, it still unlocks and locks the car.
  • Radio gets power to it (although asking for code due to being disconnected)
  • Interior lights seem to be working

When you turn the key there is no reaction, no lights on dash and no power to windows or stuff like that. Only one red flashing dot (immobiliser?) Which I believe normally flashes anyway untill you start the car.

What we tried so far:
  • Connected jump leads to battery, still same thing.
  • Bought used ECU which was coded and still same thing.
  • Replaced ignition switch, still same thing.

So far no luck, maybe some will have an idea what to do next?

Weird thing is, accidentally held unlock button on key and it opened the windows but would not close them now. Even from key.
Once it did show up light on dash after sitting for a day but as soon as you tried to start it all went away.

Thanks in advance.

I think it sounds like your instrument cluster has bad solder joints, try a good bang on top this some times gets it working again but not a fix it will need re soldering.
