No instrument lights / Starting problem - GOLF 1.9 TDI 2005

[VWGOLF4-MOTION]

Hello.
And first, thanks to those of you who can help me with this. Have tried searching the forum for clues, but now I need some more specific help.

The car will start and run for 1-2 seconds without problems before dying. But there is no instrument/warning lights in the instrument before or after it starts, only the milage and outside temperature showing in the display. Electrical windows, radio, locking system and such are working as normal. It's a 2005 VW Golf 1.9 TDI 4-Motion, engine; BKC/BKE

Things I tried:
1. New and fully charged battery
2. Spare keys and also a new key with new immobilizer programmed
3. Checked all the fuses and relays next to the battery and under the dashboard, even tried to change some of the relays.
4. ''Vag-com readout gives limited information as it can't fully connect with the ECU'' -what I were told by the workshop

Things I still have to try or hopefully first exclude with your help:
1. Diesel pump. It seems to work, and the one under the back seat deliver diesel to the pump. And if there were a problem with the pump, would the car start every time just fine, but cut out after 1-2 secounds? Also it does not explain the missing lights in the insturment panel, or would those be missing if there were a problem with the pump?
2. Ignition switch? I read in the forums this were mostly a problem on the older generations? Also this were a sudden problem accuring, with no warning or other faults. Also I tried to turn over the key very slowly, ''wiggle'' it, etc, no difference. Also it seems like most people having a problem with it don't get the car to start at all?

Open for new ideas and all the help I can get

Du har ikke fått vann rundt ecu sikring boks i motorrom.?

Her er det ecu/comfort modulen som ikke kommuniserer sammen med bilen tenker jeg, her trur jeg ville tatt en ny oppdatering på Comfort modulen og ecu.

Altså få det programmert dette på nytt...

[VWGOLF4-MOTION]

Hei.

Takk for svaret. Det var mye korrosjon/irring rundt ledningene/sikringene på front siden av sikring/rele panelet ved batteriet. Men har pusset bort dette og målt/sjekket alle ledninger/sikringer, ingen forskjell. 

Jeg kan ikke så mye om biler. Men kan du forklare litt rundt hvordan comfort modulen kan gjøre at bilen ikke går mer enn 1-2 sekunder og det er ingen instrumenter? All elektronikk jeg forbinder med med comfort modulen virker som det skal?

 

Takk igjen:)

[opel astra]

Comfort er den som styrer all elektronikken som er inni bilen.

Både til tening og alt du har i displayet på bilen.

Også om ecu har blitt utsatt for noe så kan den også gi feilmelding.

Nå har jeg litt mistanke på at du har kanskje at  problemet ditt er.  Immobilizer control module j362 som igjen gjær så at motoren blir stengt/slått av.

Regner med at det er denne du må se nærmere på..?

Enten ingen kontakt strømbrudd feil/defekt må byttes..

[Jesper1201]

Har du fått tatt en diagnose?

Kan være lesespolen på tenningslåsen som er defekt, da vil startsperren slå inn.

[opel astra]

Jeg mente da at det kom opp varsel på startsperren. Om det hva feil på den eller er jeg heil på jordet nå Jesper.

Men det kan vel kanskje være stor mulighet at det er den.

[Jesper1201]

Jo, egentlig burde den det, sammen med meldingen "immobilizer activ" i displayet. 

At den stopper etter 1-2 er typisk startsperre feil, men ikke garantert.

[opel astra]

Ja jeg mener at det er immobilizer Activ som kommer opp. og dette henger jo egentlig sammen.

Og skulle gå an å lese dette ut med vag com.

Mulig omprogrammeres. at det er en liten feil som kan rettes opp hos møller. Eller med vag com

[VWGOLF4-MOTION]

Det er typisk startsperre ja. Derfor jeg kjøpte ny nøkkel og fikk denne programert med startsperren, men var ingen forskjell. Men problemet er også at det ikke kommer opp noe annet i instrumentpanelet enn km-standen. Ville ikke alle lys kommet og gjerne en egen varsellampe for startsperren om det var kun den som var problemet? Virker som det er noe som hindrer tenningen å kommunisere med ECU som igjen trigger startsperren, som også kutter instrumentene?

[opel astra]

Nå er det Comfort modul som styre alle varsellampene.

Så dette henger nok sammen, og da får heller ikke bilen kommunisert med ecu.

Og om det er feil på Immobilizer control module så vil heller ikke bilen starte, så har du feilen som Jesper sa.

Dette kan du ha fått problemer med etter du fikk programmert nøkkelen.

Kan også  plutselig oppstå om det er noe strøm feil på bilen.

Det kan hende du trenger å få dette opprogramert .

 

Om du har vag com eller kjenner noen som har, så ville jeg prøvd å ta en test med den.

Eller se om noen her kan ta en diagnose i nærheten av der du bor.

[VWGOLF4-MOTION]

Okei, takk. Skal prøve på det i morgen. Bilen står på et verksted som har vag com, men har overatt feilsøkingen selv da jeg fant ut dette ville bli uendelig dyrt å betale en mekaniker til å gå over alle mulige feilkilder.

Men, et spørsmål. Trodde instrumentpanelet/varsellampene var en del av ECU/koblet direkte til ECU?

Skal også gå over jordingspunktene, spesielt til ECU. Har søkt etter en liste med jordingspunktene, men har ikke funnet dette enda. Vet du hvor jeg kan finne en slik liste?

[VWGOLF4-MOTION]

Dette er alt som vises i instrumentet før jeg setter i nøkkelen, etter den er på ''on'', mens den starter og går 2 sekunder og etter:

Tekte du på kablene ut fra ECU..?

Update about the ignition switch(2); There is no power coming from the ECU/engine bay to the ignition, still it starts for 2 seconds. Vag COM also had connection with the ignition or cluster? (repgrommed the new key with immobilizer). Wag COM seems to have no connection with ECU as it seems like the ignition is turned off since no power reaches the ignition?

[opel astra]

Mulig du har montert dette feil når du byttet dette her.

har du sjekket om det kommer strøm til ignition switch bryteren?

Har du prøvd dette?
