Im driving a Golf5 2.0 FSI tiptronic,Japan.i have been using it for a year now,bt for the past for months it has been giving me a problem which the mechanics I have consulted couldnt deal away with.The car's performance is not satisfactory ever since the problem started,it****** the gears during change up and change down and sometimes it even produces some sound as if the gearbox is under stress,more especially when changing from gears 1-3.It also shakes at the front when travelling between 60 and 90km/h.What could be the problem and how much could this cost me?
