I just bought a 2006 1.4 S a few days ago & i thought the revs were a little high, but always had diesels so not too sure. When doing around 50mph its at approx 3000 revs & when in 5th gear it sounds like it almosts needs another gear to go up into. Not sure if this is normal for this car?? Theres also a crackling noise from front driver side i can hear when window is down, again when doing around 50mph and usually turning right. I didnt think it was a cv joint as its not really a knocking sound but maybe this is how it starts?? Any ideas would be much appreciated!
