Rear seat rattle, usual fixes not working

[AceRimmer]

<sigh> Another fun problem has arisen w/ this car. Again. So my rear seat began to rattle a year ago. I did what I did w/ my GTIs, put some electrical tape on the latch and it went away. Now it's come back w/ a vengeance. Since electrical tape wasn't working I tried tesa tape. Nope! So I tried greasing the latch and lock. Nope! So I stuck thick foam next to the latch so it placed increased force on the lock when the seatback was up, which would increase tension and minimize jiggle (make sense?). Nope!

Those are all the ideas I can think of or found. The only thing that works is just keeping the seat folded. It's ridiculous. So, aside from tearing apart the seat (found a youtube vid showing how), WTF could I possibly do? It's incredibly obnoxious on the freeway. Keeping the seatback permanently down isn't a viable solution. I don't want to get rid of the car but it's doing its best to drive me to that point.

Check the seat hinges. Sometimes the plastic covers over the pivot points get loose and rattle. A zip tie or a bit of foam shoved in there can shut them up.

Also, press down on different parts of the seat back while driving to isolate the exact spot. The noise can travel, making the latch seem like the culprit when it's actually something else, like the headrest posts or the seat belt buckle.

Same issue here, i belive its from the inside of the left seat with arm wrist , i was happy that i fixed my clicking noise and now this
Did you fix it? I don't want to open my new car seat
As much i have seen positive reviews about it praising it as german competitor and none has mentioned the downsides

No fix. Just learning to live w/ it now as it's become so intermittent.

kenobi117, it shows you have a 2025. I'd take it to the dealer under warranty. My 2019 has expired but my dealer did A LOT of rattle fixes when it was under.

My last four cars before my two G70s were a 2017 BMW 540, 2016 Audi A7, 2015 A7 and 2012 BMW 550. The 540 had a rattle in the back seat area that they spent several thousand in warranty fixes but never did fix it. Ditto a rattle on the passenger door one one of the A7s. The 550 needed injectors on one bank replaced at 23,000 miles, front grill that opens and closes had to be replaced on the 540 - don’t recall the miles but it was under 20,000.

I have also had three BMW motorcycles. Two of them had problems at low miles, I won’t go into the details.
