I had a similar thing once when i took a diesel car to the dealers and it came back worse, lost its torque band. But i will say it is normal for a diesel to vibrate when its very cold. Well it is with diesels i have owned
I am not sure what to suggest. I know this may sound silly but was the weather warmer before you had it serviced?
Yeah sounds like the same problem, yeah thats what i thought, like the cold weather takes its toll on all cars across the board but i dunno, just makes me feel s@£t about the car ya know :/ yeah it was serviced in july/august and by my dads friend who owns a local mechanics, big service, new pads, discs oil filters fuel filters pollen and so on :s
as for the squeaking problem, i thought it was the fan belt, and when i spray wd40 on it it solves the problem for 30 sec's tops then its back to normal, not really noticable unless your listening for it but none the less i dont like the car running anything than 100% :s but i asked a friend last night and he seems to think it could be the bearing away on the fan belt tensioner? would this sound right? \
