Buenas tardes,

Tengo un Octavia II con motor BKD y 138.000 km. Hace dos días, al incorporarme a la autopista, sobre las 3500 rpm me entró en "limp Mode". Paré en la siguiente salida, apagué el motor y reaundé la marcha continuando sin problemas. Después de esto, he probado durante estos días subiéndolo de vueltas y no me ha vuelto a dar este fallo.

Tras hacer un AutoScan con VagCom arroja estos errores:

Tras navegar un poco por el foro he visto que se trata de una sobrepresión del turbo y que puede deberse a que esté el turbo sucio, la N75 falle o haya algún sensor defectuoso.

He hecho un LOG de los canales 003 y 011 entre las 1000 y las 4500 rpm. en 3ª:



Con estos datos, ¿se podría concretar el fallo o habría que probar varias cosas?

Muchas gracias por adelantado y disculpad si he metido la pata con algún término o al hacer algo ya que soy un neofito de la mecánica.

Un saludo
