Cdruse- What was the end result? Has the problem been resolved or did you ditch the car?
I have a 2011 335 x-drive coupe and I began have the SES light problem a couple weeks ago. I've brought it in once and they replaced a "fuel tank valve." The light then came on a few days later. Now I am supposed to be waiting for a new hose that is coming from Germany. The car drives fine but the SES light is on.
