Hi, I recently purchased a 2004 BMW 330 ci and after one week of driving a few issues have come up.

First, after getting ON IT in a quarter mile, I noticed a nasty odor and smoke coming from the engine bay.

Second, now every time I drive it I smell the odor, though I have stopped driving @ high rpms.

Third, one time I started it and it idled very rough.

Finally, the Service Engine Soon light came on tonight.

What could these symptoms indicate?
