Sunet de la motor la rece

Salutare.

Problema la un bmw 120i automat:

Cand e rece afara si stau pe loc in D, se aude o tacaneala (ca de tabla - metalica) de la motor. Se simte vibratie si in pedala de frana sincronizata cu tacaneala. Daca nu e foarte frig, odata cu incalzirea motorului, dispare complet. Daca e foarte frig, tacane non stop. Tacaneala se aude considerabil mai tare cu geamurile inchise; daca deschid geamul sau portiera, se aude mai putin sau deloc. Am fost la un prieten si am urcat’o pe elevator dar nu am reusit sa vedem sau sa ne dam seama de unde se aude.

Daca o scot in N sau P se opreste. Daca dau drumul la frana si incepe sa mearga, se opreste.

Turometru nu are fluctuatii, nu are pierderi de putere. Cutia nu smunceste deloc.

Masina are 170.000 km. Am facut schimbul complet de ulei in cutie (cu spalarea cutiei si apoi ulei si filtru nou). Tacaneala era dinainte de a face revizia cutiei.

Toti cei pe care i’am intrebat au zis ca daca avea probleme cutia “mi’as fi dat seama”.

 

Va rog, ajutor!!! Ma scoate din minti zgomotul asta.

Multumesc anticipat 🤘
