‘Clink’ noise when starting off

[Redstevo77]

Still really new to Z4 ownership but as the weather has now improved I’ve been getting out in the car.

I’ve noticed an intermittent ‘Clink’ noise when I take up the drive in first gear. The noise comes from the rear but unable to tell if it’s off side or near side. It’s recently passed its MOT and I have even been under the back spanner checking all the nuts and bolts and all seems good.

It might just be normal being a rear wheel drive but wondered if anyone had any thoughts or advise?

Thanks in advance

I wonder if it's a broken rear anti-rollbar link? Had similar on an E46 coupe. Just a thought.. could be anything.

Hi Redstevo77. If it makes the noise when taking up drive in 1st gear does it also do it when reversing ? If so it is likely to be worn/dry splines on the differential input flange. Mine does it if I'm a bit clumsy in 1st gear or reverse, although it is more of a 'clunk'. I'm waiting until I refurb the rear subframe next winter when I shall be applying some fresh grease to the splines in question as part of the job

Probably this. Mine does it too

Could also be a worn donut - its a rubber coupling on the propshaft. I replaced mine as well as regreasing the input flange. They do dry out and probably sound worse than they are but it is an annoying noise I recall.

Did this problem get resolved?? Mine makes that exact noise when I first start moving. It also happens if I've been driving forward, then stop and put it in reverse. My mechanic says it's the brakes slightly shifting and that it's not a problem. That doesn't seem like the right answer to me, though.

I recently had the differential bushings replaced and that fixed some other creaking noises, but the CLINK sound persists.
