We have a 2009 335i Sedan with Sports Package. Tonight when I started our car the Service Engine Soon light came on on the dashboard. We have had our 335i since mid March, and have only 6300 miles on the odometer. I was quite surprised to see this message come up. As you all know, the normal BMW service is one year or 15,000 miles whichever comes first. Has anyone had this light come on so early in the Mileage or months that they have had a new 335i ? The car runs great , and we love every mile we drive in it. We previously had a 2006 330i which we turned in to BMW of San Diego in March. I look forward to hearing from all you 'Festers. You are always great with advice and suggestions. I plan on calling my SA on Monday am, but I would appreciate any insight from my fellow 3ers. Enjoy the rest of all your weekend.:thumbup: Thanks in advance for your input.
