problema s3

[ziosam]

allora ieri il meccanico mi ha cambiato la valvola canister, quando la macchina e calda il problema e sensibilmente diminuito , da uno a dieci e migliorata 8 , ma da fredda lo fa sempre come prima....settimana prox chiedo di farmi controllare quello che mi consigli , ma e possibile che la centralina non registri nulla di anomalo , pur essendoci un problema ?
la canister pero era stata segnalata

provato a cambiare le bobine...nulla il problema persiste....
uffaaaaaaa

Dovrebbe essere la valvola che apre per il recupero dei vapori della benzina/olio.
Al posto che essere dispersi all'esterno, vengono immessi in camera di scoppio.

E' comunque un possibile inizio, ma non penso possa essere quello il tuo problema.

Farei controllare iniettori e pompe varie (compresa quella del serbatoio come suggerito da max.85).

pompa benzine dice che e ok...domani mi fa prova conpressione...stiamo andando alla ceca

[max.85]

come fa a dire che è ok? a orecchio? fai controlli approfonditi perchè sennò non risolvi...

[Roby R.R.Racing]

finalmente oggi la centralina ha registrato un errore: errore valvola canister p0441....almeno adesso ho un inizio , il meccanico mi ha ordinato il pezzo, speriamo sia solo quello...avete mai avuto sto problema? a cosa serve sta valvola ?

oltre all'elettrovalvola canister ti consiglio di cambiare anche il serbatoio canister con relativo tubetto con valvola di non ritorno,
intorno a 100mila km iniziano ad intasarsi.

provo anche quella,,,grazie....ormai sono stufo, e da due mesi che ci giro intorno ma non ho risolto ancora nulla......il meccanico ha provato un po di tutto , ma adesso non so più che pensare

ogni buona proposta la prendo come oro colato, hai avuto un problema simile?

[max.85]

io la mia esperienza te l'ho detta...devi cercare di capire cosa può essere e arrangiarti...il meccanico non si prende a cuore queste questioni...io sulla mia ci avrò messo più di un anno a capire e a forza di cambiare pezzi (portata più volte in officina audi e da amico poi ho cambiato da me perchè stanco bicchierino pompa, pompa benzina di alta pressione, sensori sulla pompa benzina, e alla fine pompa benzina serbatoio ed era quella)

[ziosam]

@max.85

Che problemi hai avuto?

Comunque, concordo anche io che siamo di fronte molto probabilmente ad un problema di alimentazione. I log, se fatti bene, aiutano a capire cosa succede nelle varie condizioni di guida. Ti consiglio ti acquistare un cavo e fare da solo, a volte è meglio di un meccanico in quanto tu riesci bene a seguirti la macchina con il tempo necessario, non sempre in officina lo fanno, si limitano a guardare nella memoria errori se è presente qualcosa e basta. Ma in casi come questi, 9 volte su 10, non viene registrata nessuna anomalia.

cavo acquistato...appena mi arriva mi metto dietro a cercare .....per primo controllo i canali che mi hai consigliato...
anche perché adesso il problema si e accentuato, specialmente se la macchina sta fuori al freddo

[ziosam]

Sarebbe utile fare un log nelle stesse situazioni in cui si verifica il problema, se serve ti dico i canali da misurare.

Canale 3
Canale 20
Canale 115

ho fatto alcune scansioni, questo e quello che mi dava mentre mi faceva il problema, qualcuno che e capace di tradurre
per me e arabo

[RPCorse]

Allora, l'unica cosa che per ora appare molto evidente è che nell'ultima scansione, delle 18:55:48 hai un evidente calo di anticipo, tra l'altro in una condizione blanda con poca richiesta di carico motore, quindi eri con un filo di gas.

Il ritardo dell'anticipo lo vedi qua:

-3.8°KW Cylinder 1 Ignition Angle Delay
-4.5°KW Cylinder 2 Ignition Angle Delay
-6.0°KW Cylinder 3 Ignition Angle Delay
-5.3°KW Cylinder 4 Ignition Angle Delay

Ora, arrivare alla soluzione del problema, la strada è ancora lunga, quindi armati di pazienza.

Che valori hai di:

- short term fuel trim
- long term fuel trim

Per visualizzare tali valori, Measure Block e seleziona blocco 32 per il Long Term Fuel Trim, il blocco 1 o 33 per lo Short Term Fuel Trim.

[ziosam]

prova a vedere se e quella giusta, perché non la trovavo...
gia che cero ne ho fatte altre
