Just thought I would follow up here on the noise i had with mine.
Took it in and they replaced the anti-roll thing on the left side, but the noise was from the rear driver side brake.
For some reason the pad wasnt sat right, they had to do a bit of welding to the caliper that holds the pad so it would hold it correctly. They said the one side of the pad was down to the metal and the other was virtually new!
The fixed the caliper and replaced both rear pads and discs.
Noise gone, brakes awesome!
£340 all in.
They also said they could get new calipers in for £130, but were saying the fix above was just as good, while saving me the cash!
