Falta de Potencia S3 1.8T 225cv

[VagS3]

Hola a todos,

Desde hace un tiempo, mi coche ya no es el mismo...le noto mucho mas perezoso que antes y no tira igual...
Pensaba que igual eran imaginaciones mias, pero hace un par de semanas lo llevé al banco de TLR y me dijeron que estaba dando 196 cv!!!
En cuanto salí lo lleve a la Audi y me dijeron que ellos veían todo OK...
EL Vagcom no me da errores, he sacado un log del grupo 115 y del 003 del Vag por si alguien sabe interpretar los datos y me puede hechar una mano pq ya no se que hacer...

Muchas gracias y perdón por el tocho

PD: si este POS no debería ir aqui, indicarmelo y lo pondré donde corresponda.

La verdad es que no veo nada claro estos números... no puedo interpretar nada.

De cualquier modo si el VAG-COM no da ningún error, entonces hay muy pocas cosas a revisar ya: Pequeña fuga (raro que no la oigas), el caudalímetro y el sensor de temperatura.

Si el cauda lee por defecto o el sensor de temp. da falsas lecturas por exceso, hacen que la ECU haga bajar el rendimiento del coche y nunca (repito si no están rotos, solo están ligeramente "tocados") dejan avería registrada.

Intenta probar con otro cauda o pilla uno de canje o desenchúfalo directamente y cambia sin pensarlo el sensor de temperatura de líquido refrigerante... y nos comentas.

Un saludo.

Si la perdida es principalmente en "altas" 5000 pa'rriba, tienes muchas papeletas de que sea el cauda.

Si lo llevaste al banco de TLR, podrias pegar aqui la gráfica, que ayuda casi mas que los logs de vag-com.

PD: la próxima vez que saques log, intenta hacerlo de un o dos canales a la vez como mucho, ya que cuantos mas canales, menor muestreo, menos información y menos veráz, el cablecito tiene sus limites.
