Good morning to all members ..I am a new addition to the BMW world ..and have just brought a 2007 2.0d X3 6 speed manual ..it is in fairly good condition but does have a couple of issues that I would like some advise on ..car drives really well in normal conditions apart from lack of acceleration over and above 2500 rpm seems to hit a flat spot or limp mode as I move up through the gears all most like a rev limiter ..my other question is about headlights ...the nearside one has been damaged in the past and I wish to replace it .but it has a grey background as apposed to the normal black ??my car was registered in july 2007 .cant seem to find a compatible one any where ..could I fit a new pair of the earlier say 2006 model ..they look the same except for the colour ..I am based on the south coast of England any advice would be gratefully received ..
