    About a month ago I bought what I thought was a 2003 330xi in good condition. It was only after getting it home that I noticed the title and the VIN plate said it was actually a 325xi. I know I should have seen this before buying, but for whatever reason I didn't notice it. After contacting the...

    The other day I decided to clean out the MAF sensor on my '05 325i, and used the Video in the link as my guide. It did improve the performance, and drove it around the area I live that whole day plus to, and from work for the next day. (about 14 miles each way at about 55-60 mpH) The third day I...

    Hey guys, I've had my 2001 330xi (85K miles) for a couple months now and recently noticed poor performance including rough idle and a few stalls when I came to a full stop.
