My 2000 Volkswagen is knocking / rattling

Hello, noises like this are best observed by local technicians near you who can hear and give a really strong educated guess as to the source. This can isolate to an internal engine concern, or even an outside accessory concern. Too hard to guess from there. I hear you've had a bunch of work, but that doesn't exclude those items from possible concern, unfortunately.
