Three problems related to alternator/generator/regulator have been reported for the 2007 BMW 335. The most recently reported issues are listed below.
Driving normally, about to make a turn onto a street my power steering fails and I get a light on the dashboard about battery charging malfunction. Upon further investigation it turns out my accessory belt that drives the ac compressor, power steering pump and alternator was completely shredded and not on the pulleys. I have damage to multiple pulleys in my car. My power steering pulley is missing big chunks because of impact with the sub-frame. This is a known service bulletin ( sib 11 09 08 ) the power steering pulley impacts the sub-frame because of motor movement when hitting bumps etc. . This caused my belt to be ripped into shreds and break off big chunks of my power steering pulley.
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.
