Boxster Roof - Scratchy Staticky noise??

Hey all,

I brought my wife to the train this morning in the Boxster as it was above freezing and I'm working from home. On the way home though, I noticed something that I don't recall hearing before so I'm pretty sure it's new.

It sounded at first like a bit of static on the radio but then I muted it and realized it's coming from the rear section of the interior roof fabric. The sound is almost like fabric tearing or scratching or something. When I got home and parked, I noticed that if I press on that rear section, it makes a sort of crunchy noise so I'm fairly certain that it's just that noise as I'm going over bumps in the road and what not.

The inner lining is stretched taut and feels very elastic. The noise is as though there were a bit of very old foam between the two layers and when I press lightly on the inner layer, it's crunching that foam just a little. I think that's my best description of what it sounds like. The front section right over my head makes no such sound. It's just the rear section over the roll bars.

Again... the weird thing is that I've never noticed this before. I'm sure it has to be a new occurrence. It's not horrible or anything, but definitely something you wouldn't miss as it was fairly constant.

Has anyone had a similar issue and know of a resolution?

I have noticed the exact same staticky noise from just behind my head in the roof from the inside. It's a 2014 and I've owned it a year but first time hearing it in the last couple weeks
It seems there’s no definitive answer on this one. A couple of observations having had this issue on 2 Boxsters now:
  • Sound travels in the cabin so pinpointing the location is difficult. Rollover hoops being in contact with the soft top headliner is what may be causing it.
  • Rollover hoops trim is prone to be the source of creaks and rattles which are easily cured by spraying a silicone lubricant between the front and rear pieces (some folk choose to remove the front piece for this). This is what did it for me, I think.
  • Failing the above, you could try getting your hand inside the soft top when it’s in half-open position to see what creaks and adding a bit of lubricant to that spot.
  • It doesn’t help that this noise seems to come and go with the change of temperature and humidity so not easy to diagnose
Good luck fixing it! Let us know how you get on with it.
