V 50 D2 motor clutch and tightening problems

Hello together, drive for about three months a Volvo V50 D2 and have the feeling that the first gear is really only usable for starting up and not for accelerating out. Also I have had problems with the clutch from the beginning (running), and after longer city traffic it has come off the engine room so funny. Furthermore, the engine makes funny noises at speeding up in the second and third gear. The workshop told me that it is the normal starting noises, whereby I drive already 6 years Volvo V 50 “,0 D and have not noticed these noises so strongly in any Volvo yet
