I'd agree with that. Either a broken spring or anti-roll bar drop link.

It is under warranty and it has been back to the dealer, who I do have infinite trust in, have dealt with them for years!! They can't find anything wrong, which is why I wondered if it is characteristic. All other replies (with thanks) wouldn't explain why this can happen on any of the four wheels, hitting a bump. I will just put up with it as it's not constant.

Thanks!!

A couple of years ago (2019 I think) an elderly relative of mine bought a new Golf. Within a couple of months there was a suspension knock coming from the front. It was quite loud. It went back to the dealer but they claimed 'no fault found'. I laid down and felt around various suspension components whilst my son pushed down on the front struts in turn. Pretty basic stuff. It was very easy to feel a lot of play at the bottom joint of the front NS drop link. How the dealer could miss this was unbelievable. I wrote a note for the owner and he took the car back to dealer, who replaced the drop link. No more knocking. I guess it was defective from manufacture..

It's amazing how much the sound of even the tiniest amount of play in an anti-roll bar drop link will amplify when you drive, so if you have any play at all you should replace them.
