Does the rear bumper of a Volkswagen Golf IV Sport Edition rattle?

First of all, hello to this technically very knowledgeable forum!

What I've seen in the error database surpasses anything I've encountered before! It's also interesting to read about the notes regarding persistent customer complaints, etc.

Regarding my issue:
Since the beginning, I've had a rattling noise coming from the rear right side of my new Golf IV TDI Sport Edition 3-door (96 kW) manufactured in July 2002. The workshop supposedly already replaced the upper damper bearings, and they also adjusted the tailgate and the backrest latch buffers.

"It still rattles with smaller cross-joints etc., but not with larger bumps. It sounds like a loose, heavy metal plate in the spare tire well. A rental car with a 1.4L engine and standard suspension also had this issue, but it was very quiet."

The onboard tools and warning triangle had already been temporarily removed for testing purposes.

What else can I do? This is driving me crazy!

Hello Michael II,

The vehicle is only 3 months old; shouldn't it have the latest locking mechanisms installed?! The noise doesn't occur during changes in load, but only when driving over transverse joints in the road surface.
The door panel on the passenger side had been making noises before, but the workshop was able to fix that successfully. However, the rattling sound coming from the rear of the car remained unchanged.

Could the problem also be related to the fuel tank (e.g., the lift pump, float valve, etc.)?
Or the gas springs of the tailgate? Is there any known issue with those?

Thank you!
