I own as second hand 2023 Mk4 Jazz I love it, but it has an annoying rattle which appears to be coming from the rear of the car around the offside boot area. It's only audible if driving at less than 15mph on uneven ground. Above that speed, and on smooth roads, it can't be heard; I assume that road noise drowns it out. I've tried all the usual tricks to try and locate it: emptying the boot; removing the tyre kit from its cubby hole; attaching all the seat belts; driving with rear seats raised; driving with rear seat backs lowered. All to no avail.
The car handles perfectly, and it sailed through its MOT. My local (independent) garage checked the underside of the car for any suspension/drive shaft/exhaust/heat shield issues but couldn't find any problems. They could hear the rattle so I knew I wasn't going mad, but said that they didn't think that there were any safety issues. They said that the only thing they could think of doing next would be to completely remove the lining of the boot to see if there was anything rattling around under the boot.
Has anyone else come across this problem? I don't even know what's under the boot area or how to remove the lining.
Any suggestions would be gratefully received.
