I'm clearly dealing with a different, mostly minor noise compared to what's been posted by others above.
Some of these more serious issues seem to be steering geometry related; so I would be questioning my track-rod ends, steering knuckle, ball joint, bushings etc. i.e. The sort of things that - if defective - will make a single loud clunk when any sideload is applied. I'm not trying to guess the faulty component! But the point is to discover
how to recreate the issue as reliably as possible, then document that on paper for the mechanic to diagnose. Also say if it's intermittent.
Other noises like rattling under particular circumstances (e.g. acceleration) could be anything to do with torque strain; so maybe it's internal to the gearbox, but it could also be rear suspension compression / mounting, engine mounts, inside the differential, drive shaft bearings on AWD models... way more components than I know tbh, always learning!
For noises over road bumps, it's good if you can localize the noise from a vehicle corner with this symptom. If happens in the same area every time, it's easier to ascertain it's something to do with suspension struts / coils / mounts with anything like that.
My own rhythmic noise issue will occur in the absence of bumps, acceleration. Only in deceleration with no steering input - so I've been hoping for the mechanic to use a stethoscope on my bearings, flywheel casing, etc. while the car is lifted and in-gear, some DQ381 DSG troubleshooting perhaps, but really - it's so minor I'm not sure I can even get it recorded at this point. It's intermittent and not getting worse at least.
