Two problems related to service engine light on have been reported for the 2007 BMW 335. The most recently reported issues are listed below.
Service engine light has illuminated on 3 occasions causing me to fail smog inspection the first time it happened.
While sitting still at the first incident the car stalled for no reason. Over the next two weeks the car started to run very rough and the service engine light would come on. You could turn it off and restart and it would be fine for a little while, now my engine light stays on all the time and my #3 injector needs replaced. BMW did recall the injectors for the 2008 models, but not my 2007, the cost is my responsibility and many other 2007 owners have had the same problem. I do. Have a BMW extended warranty for my fuel pressure regulator, not a recall, but they go bad several times a year. A recall should be extended for the 2007 injectors.
