Rear Rattle

Post by adann » Thu Jun 23, 2016 3:52 pm

I have noticed over the last few weeks a rather annoying rattle coming from the boot area on the drivers side. More noticeable going over uneven road surfaces and stopping. Took into BMW today who want £140 for an hours investigating to try and find the problem, and obviously further money for the fix. Have looked online and the common feeling is either the roof mechanism or a suspension issue. Has anyone had this issue and been able to fix it? If so, how much did it cost you? The noise only happens when the roof is up.

Can you record the noise or narrow where it's from by having someone drive while you listen?

It seems to be coming from the back of the car (possibly the boot) on the drivers side. I can have a go at recording it and see if it comes out.

Some sounds, especially when you are driving, are not coming from where you think they are.

Having someone else drive is a good start to allow you to listen at different angles and places without wrapping the car around a tree.

Most professions give a free quote for work they will carry out, I wonder why garages get away with charging.

Video of the rattle, it's the knocking noise you can hear. Apologies sound isn't great, best I was able to get.

Does it make the same sound with the boot roof tray up or down? Have you emptied the boot of every single thing that can be emptied?

Remove everything and road test again. Including the boot floor cover, tools, anything in the lockable box under the left of the boot floor.

I'd be surprised if it's the roof, I know the mech quite well after doing my own rattle hunting and its tight/very few components that can rattle.

The 'latched' cubby on the floor of the left side of the boot. Good for holding cleaning kit.
Why is it that people who can't take advice always insist on giving it?

Both my E89s have had it. Sure yours must.

Happens with the tray up or down. Wil have a go at what you said today and report back later.

Thanks for your help.

Happy to try and help. If go as far as to say remove absolutely everything from the car before another road test. Noises get drowned out when the roof is down by ambient noise and it can lead you to think it's the roof.

Not been out yet but one thing I've noticed is the plastic bracket on the left hand side of the boot tray is loose. Not sure if that could be the problem?
