BMW 525d E60 2006 low turbo boost - turbina?


Recommended Posts

Dupa cum spuneam si in titlu, am o problema legat de turbina - presiune prea mica. In urma testului cu DIS, presiunea nu a urcat mai mult de 1,33 bar, in conditile in care testul a fost facut la 3900 rpm. Legat de simtome, masina are lipsa cuplu/putere.

Pana acum s-au verificat schimbat urmatoarele:

 

-presiune inainte DPF- era sub valoarea impusa- nu o mai retin exact acum

-verificare actuator tubina - ok- atat fizic cat si in soft

-verificat EGR - Ok

-verifcat tubulatura/inercooler/admisie - singura problema find la furtunul de la turbina- garnitura rupta- urmeaza sa fie schimbata

-DPF-ul se v-a schimba oricum- unul nou a fost achizitionat- masina are un nr. relative mare de km si nu mai are rost lungita agonia

-Catalizatorul urmaza a fi inlocuit- un "inteligent" a vrut sa sparga DPF-ul, nestiind ca el a distrus catalizatorul

 

Dupa inlocuire catalizator/DPF/garnitura tubulatura tubina se va repeat testul la turbina. Totodata s-a verificat si fizic turbina, ea nu prezinta joc exagerat al axului, lipsa palate...etc/

 

Totusi cred ca aceste probleme vor perista si dupa inlocuirea celor de mai sus.

 

Am catuta pe forum ,dar nu am gasit un topic asemanator.

 

A mai avut cinea aceleasi simtome, sau asemenator?

 

multumesc anticipat
