@ jean019: I own a pre-lci 2007 n46b20 and didn't have any issues at all till now. bare in mind that I don't drive a lot, only 45k mlies till now. during end of January I started to hear a rattling noise from engine bay when accelerating in normal conditions with 1st gear and a bmw specialist said that its the alternator pulley. I haven't replaced it yet since I travel a lot but will do this week.
@ luke88: have you seen/ feel any lack in performance too? also, when was the last time you serviced the car?
