Please see the above link to the video for my issue. I've read a couple of posts on here that may resemble the same issue as mine but without any evidence attached. Has anyone had the issue and have had it resolved?
I'd love to hear from you.
I've also noticed that the noise appears more prominent next to the rear driver's side wheel. Sounds like it may be coming from behind there.
Thanks
Dean

Forgot to ask, does the noise change when the tank levels change?

It doesnt happen all the time but know that you've mentioned it it does seem worse with a full tank.

Hi. Can you confirm that you hear that humming noise only when around 1/4 fuel left in your fuel tank ?

That's definitely the pump in the fuel tank. I had exactly the same issue on a 2010 23i. Like you describe, the noise was worse with a full tank of fuel. It's a well know problem and fortunately for me my car was under warranty. It's an expensive fix as the tank has to be removed by firstly removing the exhaust and dropping the rear suspension. The dealer had the car for a day and a half and said the cost of the repair was in excess of £1000.

Wow, thanks for this thread! I was about to post the same thing, and the description of the noise sounds exactly as you've described. For me, it's a whine, which is noticeable each time I refuel.
I first noticed it in May, after having the super from Sainsbury's for a couple of tanks, then went for Shell VPower to see if it had any difference.
The frustrating thing is the dealer can't seem to reproduce the noise!
Any suggestions from those who have had this dealt with? I'm about to book it into a different dealer to see if they can't find the problem.

Mine was a 2010 3.0l
75% full tank and warmed up - very noticeable on idle - it was a warranty fix.

Thanks Ronk! It's booked in for a week Monday. Back to the same dealer that found and fixed my injectors.
