Only complain I have is that I feel an odd vibration on the floor at around 2300rpm in all gears. I don't know if it's normal but I am fairly sure I test drove 2 other m340i before buying this one and I don't recall feeling any of that. I have new tires now and still same thing.

Otherwise seems like a great car.

Did you get the car used?

The reason why I ask is (and this might be totally unrelated) because I got a new Remus exhaust fitted and it seems like the place I got it from didn't fit it properly because at around 1900-2200 rpm, I hear a rattle under the centre console. Similar to a vibration, it sounds like there is not enough clearance between the exhaust and the heat shield and this causes them to hit each other.

So maybe what happened is the previous owner had a difference exhaust on the car and got the original refitted and it wasn't fitting properly? So the exhaust is hitting the heat shield.

Like I said, might be completely wrong but just from my experience.
It was a new vehicle with essentially 22 miles on the odometer.
What you describe however could be similar because I feel as if the vibration is occurring at the peak of the exhaust "grunt" which is at around 2300rpm. I'll have the dealer check all that.

For me, they had to re-grease the sunroof seals. Worked like a charm.
