Noise from rear after going over speed bumps.
« on: March 13, 2020, 01:51:13 PM »
Just done a trawl through previous posts and can't find anything on this issue but it affected my previous Mk3 and this new one.

It's triggered when you go over a hump styled speed bump. It's not triggered by anything else and I mean that quite literally. It's not possible to reproduce it by bouncing the suspension and it doesn't occur if you drive over cattle grids or those much narrower speed bumps - the ones that appear to be made of rubber.

It's a creaky sound, it also has elements of a squeaky old sofa. My theory is that the bouncing movement engendered by these hump style speed bumps sets up a sort of resonance in the trim.

Does anybody else get this?
