exact ca la mine...... tind sa cred varianta cu picatura de ulei pe disc care dupa plecare se sterge..... am mai gasit referitor la tremuratul la rece mai ales dimineata pe un forum strain asta : ``What you have is the hydraulic lifts that is sticking. This is a common problem with the 3 series. Basically once you are over the warm up period, you can shut it off and drive off without any shaking, this only happens when you let the car sit for 8 hours or overnight. I talked to the dealer and they said it cost roughly about 1000 dollars b/c they have to open up the head of the engine to replace the sticky valves.`` dar nu stiu la ce se refera.....si m-am uitat si pe realoem si am gasit ceva dar e in miezul motorului si manopera ar fi criminala cred....
