Strange rattle W12 ?
 
well the W12 has had a strange rattle for the last month or so you can only feel it as a driver not a passenger. seems to feed back through the wheel and sounds like something loose behind the dash. ive replaced all the driver side arms and track rod ends ect and it drives tight as a drum.

its really bugging me now and just wandered if any one else has had this rattle ... ive tried all sorts to find it but no joy :tuttut:

any ideas ?

Calipers knocking? Give them a wiggle.

Occasional knock from front calipers
 
Re the above mentioned caliper knock, mine does it occassionally when front brakes are hot only over road surfaces which are breaking up and slow speeds Re fitting the anti rattle spring seams to cure in for a week or two I think
Have the 2007 Sport 4.2tdi brakes are 385mm discs
Any best practice?
Is a new tensioning spring with the square plate, the one that face the wheel.the recommended route to cure?
Pads are in very good condition and wear level are minimal.

Thanks in advance.

2007 4.2TDI Sport should have 360mm brakes on the front shouldn't it? 385mm is for W12, armored and S8 I thought. :Confused:
