Hello there! I'll try and explain this as best I can so here goes. My S3 has a high pitched whine that seems to be coming from the rear centre. It only appears on the overrun and dissipates as soon as I put any gas on, it also stays if i dip the clutch. As well as this the gearbox is feeling a tad weird, doesn't feel as positive as it was and if I move the lever left and right in neutral it doesn't spring back to centre quickly it kind of just slowly slides back. I'm thinking it may be time for an oil change on the box and rear diff. Anyone else any ideas? It's done 115k miles if that makes a difference. Thanks in advance for any help. *edit* it's a 2002 plate BAM engine too.
