My Focus is back from switzerland with blown turbo after 4 weeks ,now there is another problem with it I cant get it to go in gear when its cold ,got to start it up in gear then it works but its notchy until it warms up ,had a new clutch and fly wheel fitted about 25000 miles ago and only done motorway miles really since , Iam not a mechanic but read it might need bleeding does this sound like the problem ?

Possibly, as they have a hydraulic system and they're a bitch to bleed properly
