Rear deck lid rattle

[ROBD314]

Anyone experience a rattle from the rear deck lid ? I have the sun shade and was wondering if that could be making the noise. It's the same wether the sun shade is up or down. It sounds like something is loose or hanging. I've checked all rear speaker screws, car seat latches, seats, and trunk. Pretty frustrating for just having a new '16 F80 that's only 2 weeks old !!

heard something like this recently. it was extremely subtle, but I think I have this same issue. can only hear it when the music and A/C are off and you go over bumps. subscribed for any updates.

could it be the first one in this thread? my car is on its way back from Europe, so I can't test it out. hope this helps - post up what you find if you do try anything here.

Yeah, Its pretty subtle, only when AC and radio are off. Pretty annoying when I'm on a phone call though. I tried driving with all the latches open and thats not the issue. I went through the whole rear of the car last night and pin pointed to the whole deck-lid itself ! when I press down on it it feels like is hitting something and making the noise. I take my car in for its 1200 mile service next week so I'll see what they say.

I heard a rattle whenever I closed (slammed) the trunk closed. Turned out the lower diffuser above the exhaust was loose. I believe the bottom is snapped on and can come loose. Something to check anyway.

Update....So I took the car into the dealer and had them check it out while doing my break in service. Turns out after taking the whole rear deck off, they found that the plastic brace that locks it into place was cracked !! Now they said that it is possible It could of happened in transport but most likely It was the window tinters putting too much weight on the back deck and cracked it. Good thing is that they warrantied it and it is all fixed !! So beware of who is tinting your car and tell them that the rear deck on the M3's are pretty fragile.
