Don't like the idling sound!!
I switched from a E90 328xi to F30 328i last last month and I find that while idling the sound feel so less of a luxury car. I also noticed the same when taking delivery but shrugged it off thinking it is just new car sound.
I metered 1600miles so far and the sound is still the same. I don't know if it's my car or just that it is common with everyone. Should I go to the dealer and have it checked?

It's the same with everyone, the 4 cylinder turbo sounds like a diesel when idling. But then again, I don't idle much, at most at the lights, and then I'm inside the car so I don't hear it lol.

That's just the way it sounds.
Just enjoy your increased horsepower, torque and fuel economy! FWIW I just put a BMW M Performance exhaust system on mine and I LOVE the way the car sounds now. It's not "boy racer" loud, it sounds just right. There are lots of video clips on line of different systems you can check out. Then you wont notice the unpleasant idling sound it makes. |

Direct injection engines have that loud clicking noise from the injectors, and of course a 4cyl is less smooth sounding than a 6cyl, all things being equal.

That is one of the largest factors in the sound of the N20, the DI.

I really hate this assumption.

My interest in the 328 vs. the 335 was primarily the motor--we needed a platform to develop parts, but it also was for fuel efficiency. I've been fascinated with the idea of a BMW that makes 300hp and gets 30mpg.
With the mild tune that we have on the car now, I am satisfied with the acceleration (although it holds no candle to the shop 135i big turbo FBO with 481 ft/lbs of torque), but I am disappointed with the sound of the four banger under acceleration. It doesn't have the sound of a premium car. I don't mind it at idle, since I can hardly hear it. |

Well... You want to save money and you end up negating the difference or most of it, by installing an aftermarket exhaust. You could have ended up with a 6 banger, a nice sound and great performance for just a little more if you had realized your mistake in the first place.
Only thing I can think of outside of the money factor for getting a 328 over a 335: - Better fuel economy (get a Prius if you're green or a Kia if you're broke) - Better weight distribution (very slim difference noticeable in racing only) |

Here in the US it's not even $5k... Which incidentally is the price of a high-end exhaust system inc. install. And it's not like that's going to fix the noise under the hood, just behind the car (artificially). |

What you're saying in other words: "It's stupid to spend 1.3k to upgrade the sound on your 328i, because for another 4k you could have gotten a 335i. And if that additional 4k actually matters to you, well then you're just a broke person who's reasoning I don't understand". A) I've heard a 328i with performance exhaust, and a 335 with stock. Personally prefer the 328 with perf exhaust at higher revs. So no, just upgrading to a 335 would not be the same as installing the performance exhaust on a 328. B) For a lot of us here that additional 4k is a size-able chunk of money. Does that mean we're broke or poorer than you or whatever? No, it just means we have different priorities. |
