I think I have solved the infamous 9N3 Polo rattle this weekend..

on mine at least, please investigate on yours and let us know!

it is NOT: LCA rubbers> done (money wasted)
Shock Mountings & Swivel bearing>done (money wasted)
CV's and ball joints> was on my way to buy on saterday before i decided to have a propper look again.

IT IS THE BLOODY BRAKES! THE CALLIPER IS MOVING AND HITTING THE LOWER EAR OF THE HUB WHERE PADS SLIDE. (FS-III type callipers)

The three spring tabs on the pads to be more precise. On my car the I bent the big one (the one that is facing forward) on both inner & outer pads to get them into the calliper, resulting in not enough tension exerted on calliper alowing it to move . I Could move the callipper with my fingers. If you hit it with a rubber mallet, clang, clang clang!

Then at the lower ear of the hub where the pads slide and bottom of the calliper hooks onto, is loose and vibrates , resulting in the flippen rattle!
(I DID NOTICE WHEN I BRAKE NOISE WENT AWAY A LITTLE..)

I rebent the tabs for a much tighter fit, drove over every piece of brick paving
i could find on sunday, NOISE GONE!!!!!!!!

I also noticed that the Slider Pins And their rubber guides in calliper are on their way out too. Will do that this weekend.

I hope this helps a few guys from redoing their entire front suspension for nothing.

Great going. Very happy to hear you found that dreaded knock. I suppose I will also give it a shot and hope I land up with the same results as you.

Lol will check if this is my issue too, After replacing everything and giving up.. I've gone deaf to the knocking noises.

What pads are those? needs to be a nice tight fit into the caliper.

mine are ATE, but all for 256mm polo 9n3 look like these, BUT NOT GTI & TDI

Notice the three shiny spring tabs. Unfortunately rim is in way of the spot that calliper moves and hits.
