Knocking Noise From Rear

[Hazzard]

Hi can anyone help, my car has a knocking noise from the rear now and again mainly when I turn right ( roundabout ) I've check the spring and they look fine and pushed up and down on the rear suspension and nothing :(

The only noises I've heard in back of my IQ are when I haven't secured the rear seatbelt buckles on their hooks.

3 things come in mind ...

Broken spring...

Rear-Seat-belts...

Plastic venting thing (=plastic flap that closes the opening in the rear to let the air go only outwards)...

Thanks for the help seat belts are plug in. So I'll see if its the plastic flap

Does the little plastic tray behind the seats have the turn clips either side of it to hold it in place? Mine has them but they were not fitted when I got the car and the box rattled until I put them in place properly.

Loose things in that box can also rattle and knock about.

Check the bushes on the dampers too as they could be worn but that would probably knock all the time over bumps.

I seem to remember a few posts on this forum some months ago that "eluded" to a rear nearside suspension knock from the IQ.

When I was looking to buy an IQ nearly two years ago I test drove 2 IQ's that had it and chose not to buy them because of it, this may be a different problem to yours I'm not sure.

Craig, you wrote: "Does the little plastic tray behind the seats have the turn clips either side of it to hold it in place?"

Sorry if I missed the obvious, but are you referring to the plastic grill panel attached the rear bumper area, or the removable boot box with the flappy lid?

The removable boot box with the flappy lid. :)

If you open the lid and look at the sides there are holes which allow plastic turn plugs to be fitted and locates the box against the side trim. If these are missing it can rattle and bump around.

Hi,

You might want to put someone in the back who can see if they can identify where its coming from. I also had one seat that wasn't clipped into place and would knock/tap on corners

Recently my exhaust heat shield came loose, and it made this terrible knocking noise. Had that fixed and the noise never came back. :)
