Problems with my 2004 1.9 diesel parnet.

Hi, I'm desperate, repair my partner with change of strap, all well, but ......
now you want to want and the board works when you want.
When it starts, it starts to the touch, and the instruments do not work, that is, the Reboluciones account does not work and the check is on does not recognize the battery charge.
But the engine works.
I have disarmed and disconnected everything but remains the same.
Please help, my wife loves this truck.
And if I don't fix it, I stay without my 4x4 haha, I have to walk.
Thanks or help.

Hello; I think you should reset the calculator (black box) of the vehicle. Surely, previous values ​​have been loaded, which cause a failure in reading the instruments.
