740D f01 pierdere putere


Recommended Posts

Buna la toti

 

Sunt detinator de putin timp unui BMW 740D f01 , an 2010 , km 210.000

Problema mea este cam asa : are o pierdere de putere nu tot timpul la plecare se pe loc 0-2200 -2500 rpm se simte pleca plafonata greu pana in 2200 2500 rpm dupa trage zic eu destul de bine. Cand merge bine o simti se ridica de bot asta doar cateodata . Si mai se intampla la mers constant cate o data cand vreau sa accelerez ramane fara putere la orice turatie ca si cum as ramane fara turbo la ea si isi revine dupa un minut sa Zic asa singura . Propietarul de la care am luat o zice asa : ca a avut prob cu pierderi de putere la ea si i ar fi schimbat futunele de la vacuum cu niste furtune non originale bmw si cu diametru diferit fata de ce avea masina initial. Initial avea de 3,2 mm ceva de genu si ia pus de 3,8 , 4 din cate am inteles.

Acuma intrebarea poate sa dea simptomele astea de la punerea furtunelor cu diametrul diferit?

Sau de la ce ar putea fii?

V-a multumesc anticipat, si scuzati-ma daca nu m-am exprimat cum trebuie . Sunt nou pe forum
