...and before anyone says it - no, it's not the wife!
Did a long(ish) run today and when I arrived at my destination I noticed a background whine/drone, which seemed to be coming from the rear although it's hard to tell. It was present at idle and while doing low speeds but seemed to disappear as I accelerated. Having said that it might have just been drowned out by engine/road noise. The whine was fairly constant but occasionally dropped in and out while at idle; revving the engine made no difference. All went silent as soon as the engine was switched off.
I've had a look on the net and noticed a couple of posts from E89 owners with 35i models who had a similar experience and it turned out to be a faulty/failing rear fuel pump. Not sure if my 3.0i has a rear fuel pump...
I'd love to say exactly where it's coming from and perhaps post a sound clip but right on cue, the heavens have opened and I just know when I start it up in the morning, it's gonna be quiet.
Still, anyone experienced anything similar?
