Hola a todos y FELICES FIESTAS!!!!!

Solicito ayuda.

Tengo un A6 25tdi 150cv del 2000 (c5 creo). 300.000 km

Con fallo tipo en el arranque del coche, unas veces si o otras no, se ha juntado frío y batería al final de su vida.

El lunes pasado intento arrancar el coche y ... hace chequeo, intento arranque, se mueve el motor de arranque un poco pero no puede la batería.

Dos intentos o tres y desisto.

Compro batería, la pongo y ... chequeo completo pero cuando intento arrancar girando llave EL COCHE NO HACE NADA, la llave gira hasta el final pero no hay respuesta, como si no llegara corriente a ninguna parte. El cuadro continua con luz, no hay bajada de intensidad de luz, etc. Elúnico sintoma que noto es que la luz que alumbra el botón de emergencia y el mado de luces de debajo del bolante se quedan a oscuras, como si se cortara la luz pero el cuadro tiene luz continuamente y no da fallos, pitidos, etc.

Intento arranque con pinzas, lo mismo.

Cambio bateria, lo mismo.

No se que puede ser.

No colaboro mucho en el foro, el último año no ha sido bueno ni física, ni mental ni siquiera económicamente pero imagino que todos estamos igual.

Agradecería ayuda, opinones, etc.

GRACIAS
