I just purchased by FIRST BMW, LOVE THE CAR!!! SO...all that aside, I realize from the posts on this and other sites that my 97 528i may be prone to "check engine" light probs. Any suggestions as far as what are the usual "quirks" to look out for, etc. All help appreciated. I will try to post a pic, it is stock, and a "sleeper" for a 6 cyl. Love the drive and power avail.
