Hi I was hoping someone could help me on this.

I just got my BMW E92 320d 2007 Manual serviced and noticed a week or so after this slight what I would describe as a deeper than usual humming sound that comes from the engine which sets in as the car is between 1000-1500 rpm.

Any ideas? Could it be signs that the gearbox is on the way out or perhaps something else? Someone who just sits in the car would not notice it but because I have been driving it daily I can definitely notice the difference - also the accelerator pedal seems as though it has a bit of feedback when between those rpm's (normally as the car is decelerating from 1500 to 1000 rpm. Just to add the car has just hit 80,000 miles (which i have been told is whereabouts the gearbox is on its way out). If if is gearbox how much does this normally cost and roughly how much is labour?

Any of your thoughts would be appreciated

Fingers crossed its nothing serious
