Had a towbar fitted, there is now a rattle from back lhs area. Anything wiggling about has been tied wrapped. Boot checked, wheel nuts all tight. It's definitely an outside noise. Can't find anything loose underneath, all heatshields are solid even though bent in a few places.
Found two loose cables and rusted exhaust supports up at the front, tie wrapped these till I can get them fixed.

I can only describe it as a light rattle and definitely sounds metallic.

Would appreciate any suggestions as Mrs Moby is not as patient as I am!

Have tbey done up the fixing bolts on the towbar properly? They take some torque to get them home
I'd get your fitter to check the installation it shouldn't rattle No Longer the owner of a 2013MY Fuji White GS

"Fiat Lux" a philosophy not a car

Inside or outside the car ?

There's a lot of wiring going on behind the lhs boot trim which, is a PIA to remove if you go for Fomoco genuine wiring kit.
I'm awaiting a 2nd kit for my current FL2.

Definitely outside. Can't hear it with windows up.

Starting to think if shock absorber is on its way out...

It's being serviced tomorrow as we're off campus, ping on Sunday. Will mention it to my chap.
Thanks for replying.

Any progress report on the rattle, just so I dont do the same.[/i]

It's not the towbar. I had a grating noise on rear brakes before towbar was fitted. Stripped cleaned , regreased caliper etc. Only found the noise after.
Turns out caliper is rattling.
