Seat belt knocking - Front passenger side

I have to do this too. Kind of wish there was some cushion along that side to refrain from the constant banging.

 

I have the same rattle and also a creak where, I think, the foremost part of the drivers door touches the side of the dash.
Felt tape is going on in the next few days. Door creak is not easy to locate so may be difficult to resolve...

 

Clip the belt into it's lock? Or a seat belt sleeve https://www.amazon.co.uk/Safety-Comfortable-Shoulder-Sleeve-Protector/dp/B00ESXT6UA

The problem on my S is different- unless you learn to be careful (eventually) letting go of the undone seatbelt it marks the B pillar

 

Or just keep it clipped closed?

 

Likewise a bit of felt tape on the seat plastic.

 

Withourt wishing to hijack this thread, the creak I get at the drivers door, which is not significant, and only when cold, appears to be coming from this triangle, where there is movement against the door:



The triangular piece of trim securely fitted on the passenger side. The drivers side has some play in it, where the bottom moves in and about anbout 3 or 4 mm. Is that normal, does anyone else get some play in this piece of trim?

 

Some good ideas in this thread. That knocking has been driving me MAD!
