The noise sounds like a dry oil pump whine. It used only happen rarely when stuck in traffic for a while and if I put it in neutral it would go away. It's now happening more frequently and also sometimes when I'm driving. I was thinking about changing the oil pump but I'm not 100% sure it's that. I've trawled Google and can't find a definitive answer to whether the oil pump is only driven when in drive not neutral. There's no oil leak so I'm sure the oil level is right as I serviced it myself about 6 months ago. Has anyone else had anything similar to this happen to theirs.
