Would it be worth trying to find a garage with these? And try to provoke the rattle while stationary.
Did you mean to add pic there? :-) I know what you're talking about though, jiggle plates on overhead ramps, been to 2 garages with these, including Kwik fit last night. The fact there isn't a rattle on these ramps, and when they pulled, hit, rattled everything by hand too should maybe be a major clue to someone?
By that i mean car has to be going up and down, not being shaken? I don't know, i'm at the end of my tether with this.
I'll try the suggestion about pressing the brake tonight and report back, thanks again!

Drive over a particular stretch of road that it is bad on & try it again with your left foot gently on the brakes.
What happens?
Had a bit of a brain fart there, why the 'left' foot? Lol, but obviously keeping up the speed enough and braking checking to see if anything in calipers is loose! :-) What happens?
It did stop/cut down the noise. Was never sure though if i was hitting rough enough bit roads while i was braking? I think i was though and i'm sure it might have stopped the rattling.
So it will be maybe retaining clips/loose pads then?

Ok, been in about it, it's the rear caliper slide guide pins are worn, in it's relaxed position pads rattle around, straighten floating part of caliper, no rattle! What happens?
Thanks E-Bmw! and others for their time replying!
As I have what appears to be a near identical problem on wifes Megane.
I noticed that the P/Owner had only fitted one LWR wishbone but had bought 2 & sent one back? So I bought another & fitted it (real pain), I guessed that he probably just jacked the car up & worked off axle stands.
When you loosen the sub-frame it must be with all the cars weight on the ground & torqued correctly or else you get can these noises.
I Put the car up on a ramp, undid all the sub frame bolts & dipped each bolt into a grease pot.
Torqued each one sequentially to 105NM, I loosened all of them, but only took out one at a time. Make sure you really grease them up as you are putting a fair amount of torque on them, I guess the best thing would be to buy new bolts really as they might be stretched if over tightened in the past ?...It has improved somewhat,
Also a ARB droplink is a bit sloppy, so this might be another contributing factor to the noises, will fit it this coming weekend.
Give it a go & let us know if it worked ?

Well, it's fixed, well against every grain in my body,i bodged it! Now the irony of this that my fix cost 'nothing' isn't lost on me.
So, pads that were on my car at the rear confused me to start with, one had an anti rattle spring at the rear end of it, the other didn't (i changed sprung pad to outboard position to rule that out, but couldn't get caliper back on) ?
My first thought was, well if they 'both' had an anti rattle spring i wouldn't have had this sodding problem, but they are strangely the correct pads!
So the new caliper guide pins done nowt, my thought then, and i think its my problem is wear on the pad carrier! Can only be that.
So my bodge was to sneakily wrap a quite thick piece of insulated electrical wire around the carrier where the pad was rattling off it, at the top and bottom, complete silence!! Oh joy! Not a permanent, dangerous bodge but it's working and it's not fouling anything!
Incidentally this model of car had a phase 1 and phase 2 version, mine has Renault ATE calipers on, phase two has TRW calipers, which have two different style sprung pads, and more conventional looking caliper sliders.
So, i now have a lovely quite car and it should have cost me sod all to fix! :-)

At least it should fly through the MOT So, pads that were on my car at the rear confused me to start with, one had an anti rattle spring at the rear end of it, the other didn't (i changed sprung pad to outboard position to rule that out, but couldn't get caliper back on) ?
