BMW e92 330d Diff issues
Discussion
Looking for some advice on what to do with my 2007 e92 330d manual. Its on 131k miles, but has been a solid runner without too many issues.
I have got an issue with the diff, there is a whine/howl when drive is engaged, significantly worse when coasting down from high speeds. Its not wheel bearings, I've had it on a ramp and there is no noise in spinning the rear wheel, but if you put your hand on the diff casing when you spin the wheel you can feel a slight vibration. Also, noise disappears when you drop the clutch.
As far as I understand, the diff is meant to be sealed for life, but you can get into it with the help of a specialist. I have been quoted £600+VAT to get the diff opened up, it could just be some bearings etc.
Or is it worth it to try to find a used diff and replace the whole unit, but I am remiss to do that if I end up with one that will go the same way in a few thousand miles. Or do I try to get a new diff with some peace of mind, but in the expecatation that that's a £1000+ job.
For some context, the car is probably worth about £6-7k as its a high spec M-Sport with full service history and recent tyres, service, discs and pads etc.
Any help or any links/contacts to diffs would be much appreciated!

Question is - are you going to keep the car for the forseeable future?
If no, then there's no point spending money. If yes, then have think about Birds & a Quaife diff?

for around the £1400 mark, you'll have something that made the car feel much nicer to drive (IMO), but be warned, it might just be the start....

I would like to think I will keep the car for the foreseeable future, I do about 30k miles per years so its all whether or not its worth it to keep it going. My motoring is expensive whichever way you cut it really.If no, then there's no point spending money. If yes, then have think about Birds & a Quaife diff?

As nice as that is, its probably out of budget at the moment, I have trawled ebay and found this...

Any estimates on costs for installing it?
