+CONSUMO DESPUES LIMPIEZA CAJA MARIPOSA y ADMISION

[Mahou]

Hola!

El mío, un 3.0 TDI Q T (225), le saco medias reales de 8,5 l - 9,5 l en carretera a 140 Km/h con muy poca ciudad. En ciudad salen medias de unos 11 l. Llevo llanta 19". El ordenador marca entre 0.3 y 0.5 l de menos. Lo del consumo a partir de la limpieza de la mariposa puede ser que necesite una adaptación con el VAG. Dicen que siempre que se quede sin tension debe de adaptarse.

 

Pues si alguien me dice como se hace una adaptación con el vag-com, la hago. A lo mejor si que es necesaria, pero en audi no me dijeron nada de que se la hubiesen hecho tras cambiarle los dos bancos de la admisión. La mariposa principal se la cambié yo por mi cuenta y no le hice nada, aunque desconecté la bateria.....

[rmorenoh]

pues mira

 

que es raro, porque al tener mas aire quema mejor el combustible y necesita menos, no te abra salido otro fallo por otro lado,¿ le metiste vag-com ahora?

 

 

 

hola Ximo:

 

 

Le he metido el vag y no me da ningun fallo.

Hola Vanquishrav:

 

Cómo adaptas la mariposa con el vag?

[Popen]

Bueno pues como novato os cuento las medias con el avant 3.0 tdi Q Tiptronic que tengo desde la semana pasada. En los aproximadamente 1700 km que le he hecho, mixto autopista (140-150) con el tempomat y atascos M40 incluidos la media me sale entorno a 8,4- 8,5 litros/100 km (como bien indicáis el ordenador me devuelve una de alrededor de 7,9 es decir aproximadamente 0,5/0,6 litros menor). La autonomía en estas circunstancias y al precio "fabuloso" que tenemos ahora 800 km.

Bienvenido Popen:

 

Ese consumo me daba a mí antes de la limpieza de admision y caja mariposa. En atascos de M-40 unos 8l/100 ahora 9-9.5 l/100

Hola! Yo no he hecho la adaptación pero, tengo algo de información de internet:

No se si servirá, pero viene bien explicado. Ya nos contarás si sirve.

 

El ajuste básico es el procedimiento por el cual se adapta la unidad de mariposa a la unidad de control del

motor, se memorizan las distintas posiciones de la mariposa, así como su curva característica de aceleración,

se adapta también el actuador de la mariposa.

El ajuste básico se debe efectuar en los siguientes casos:

Después de la interrupción de tensión, cambio de la batería o agotamiento de la misma.

Después de haber desmontado y montado la unidad de mariposa.

Después de haber sustituido la unidad de control del motor.

Después de haber limpiado la mariposa.

Cuando se observa ralentí inestable o caídas de rpm e incluso paradas de motor.

Antes de realizar el ajuste básico, se debe comprobar:

1. Se deben revisar todos los fusibles, según el vehículo, podremos localizar los fusibles en cuestión.

2. La tensión de la batería debe ser superior a 11.5 Voltios.

3. La mariposa debe estar en posición de ralentí, si posee cable de acelerador, este debe estar bien regulado y

libre.

4. Se debe consultar y borrar la memoria de averías.

5. Todos los consumidores eléctricos deben estar apagados, luces, luneta térmica, radio, etc...

6. Normalmente los valores de líquido refrigerante deben estar entre 0º y 50º C.

Acoplar el conector de diagnostico del Vag-Com ( ver lugares de conexión ) a la toma de diagnosis.

Conectar el encendido e introducir la dirección 01- Unidad de control de motor.

 

Verificar en la memoria de averías - 02 que no hayan averías detectadas, en caso afirmativo, borrar la memoría

de avería - 05.

Pinchar en ajuste básico - 04 e introducir el grupo 098 si el vehículo tiene cable de acelerador y 060 si tiene

acelerador electrónico EPC. Se escuchará el actuador de mariposa desde su posición mínima a la máxima y

en posiciones intermedias, el ajuste básico tardará como máximo 10 segundos. No tocar en ningún momento

el pedal del acelerador, esto provocaría el fallo en el ajuste básico.

 

Una vez realizado el ajuste básico pincharemos en finalizar emisión terminar - 06 y desconectamos el encendido

durante 15 segundos.

Nota: el ajuste básico puede verse interrumpido por varias razones:

La unidad de mariposa no alcanza el tope mecánico debido a la acumulación de depósitos carbonosos.

El calado del cable de acelerador, no está bien o no se desplaza con suavidad.

Tensión insuficiente de la batería.

El cableado, la unidad de control de motor o la unidad de mariposa están defectuosos. ( Ver comprobación )

Después de la interrupción se memoriza la avería, ! ajuste básico no realizado !

Buenas.

No he podido hacer el ajuste básico porque no me deja el vag-com. Tengo la versión 10.6.4. Mi coche un A6 3.0 Q Tdi Aut del 2006 (225cv) y en el vag, tras borrar todos los códigos de error, me meto en engine1, opción 4, aparecen 3 filas independientes donde meter grupos (001,002,003), meto en la primera 060 y pincho read y aparecen 4 valores RPM 0 TORQUE 0 TORQUE 46,2 y no se qué más 0, pero no se activa la pestaña de abajo [switch to basic settings], con lo que no puedo iniciar el procedimiento. eso sí, arriba a la izq. hay un"oscilador" numérico que oscila entre 57,3 y 63,0 todo el rato hasta que salgo de la pantalla por aburrimiento.

También lo he intentado en la opción 8 (basic setings) y al meter el grupo 060 o el 098 me dice error not acess.

Necesito ayuda.

¿Alguién que lo halla hecho o sepa, puede echar una mano?

Bueno, ¿No hay nadie que le halla hecho un ajuste básico a la mariposa principal?.....

[Mahou]

Vale, pues ya me respondo yo......

 

Los motores diesel tambien llevan una mariposa en la admision, pero su función no tiene nada que ver con la que realiza la de un motor de gasolina. En estos motores solo sirve para que el apagado del motor no sea brusco, sino que lo haga de manera suave. Esa mariposa está siempre abierta para permitir el paso del aire, y en el momento que apagamos el motor se cierra durante unos segundos y a continuación se vuelve a abrir.

Aunque haya que cambiar esta mariposa en caso de que se averie, no hay que realizar ningún ajuste básico.

Hala, por si a alguien le sirve.

Hola a todos, creo que no habláis de las mismas mariposas, el motor 3,0 TDI tiene una 1ª válvula de mariposa que es la que da entrada de aire a los dos colectores de admisión y una válvula de mariposa por cada cilindro llamada mariposa de turbulencia espiroidal (6 válvulas). Cada bancada de cilindros lleva tres de estas mariposas y las tres son comandadas a la vez por un servomotor que es el que hay que adaptar con el ajuste básico. Podéis ver de lo que hablo en este enlace:

 

http://www.audisport-iberica.com/ftp_asi/Descargas/A64F/Manual_A64F_Grupos_mecanicos.pdf

 

Yo presencié el ajuste básico de mi coche en Audi, ya que después de una reparación notaba lo que comentáis en cuanto a consumos y potencia del motor. El ajuste básico lo hicieron a estos servos, a la válvula de by-pass del turbo y a la EGR. La máquina VAS de Audi le decía al técnico que tenía que hacer y me llamó la atención que a veces pedía pisar el freno.

 

Llevo bastante tiempo buscando como hacer todo el ajuste básico y no he encontrado nada salvo esto que pongo de en un foro ruso y que no estoy seguro si es para este coche. Espero que a partir de esto alguien pueda aportar algo más.

 

Por otra parte lo que si que ocurre es que a pesar de no hacer el ajuste básico, el coche va adaptando parámetros sólo y con el tiempo las prestaciones y el consumo mejoran.

 

Ahí va el foro ruso:

 

Прежде всего огомное спасибо GOL_AUTO Маленькая посказка про педаль тормаза и полный газ и все заработало единственное в моем источнике нет ничего про упомянутый тобой 28 канал

Вообщем сейчас у меня все 00000000

 

Я думаю будет полезно для всех кому это интересно указать еще на одну мелочь что все адаптации достатчно длительные по времени от минуты до 3 или даже 4 и в заключении темы было бы полезно выложить в помощь остальным порядок настройки , что я и сделаю она есть в интернете но долго искать, кстати на этом форуме я не нашел так, что пусть бует.

Еще раз спасибо
