3-Series (E46, E90)Chat relating to the BMW 3-Series from 1999 to Current. Models include: BMW 316i, BMW 318i, BMW 318Ci, BMW 320i, BMW 323i, BMW 325i, BMW 330i, BMW 328 Ci, BMW 328i, BMW 325i/xi, BMW 330Ci, BMW 320d, BMW 330d, BMW 335d.
Can you believe this. 7k miles on my 04 330ci and the engine is acting up! Engine runs rough at idle, to the point the car shakes. Check engine soon light comes on, and stays on. Problem persists even after the engine warms up. I have a service appointment with the dealership, but they're a pta, so I don't like going unless I have to. Any simple, or common problems that I can check? Already checked the gas cap, and it is firmly in place. No changes in my driving habits (conservative), gasoline used (premium), etc. No problems with weather, I live in a south florida. Thanks in advance for any ideas or advice.
