Disappointed
 This was my 3rd BMW.  I am truly in love with this car, I have taken excellent care of it.  Maintenance wise, I have done everything I am supposed to do and more.  It only has 75,000 miles on it.  I purchased it in 2009 and repairs have been minimal until now.  The computer has been in and out (works most of the time) have been to 2 different dealerships and they don't have a clue what's wrong with it.  I can live with that, however, my emission system has caused the "check engine" light to be on because of "increased emissions" and was told by the dealer that the cost of repairing this would be more than the car is worth.  What the heck!  I live in Cobb County and am forced to get an emission sticker each year when I renew my tag.  What am I supposed to do now????  I am basically driving a car that is "totaled" because of the repair.  What is BMW thinking when they put such a system on a car?.  Would like to hear from anyone else about this to see if this is a defect on this car and if there is anything that can be done by BMW to remedy this.
