BMW X3 E83 2.0D
 

Hi guys, new here, popped in for some advice(hopefully).

Bought the wife an X3 back in April when our son was born and having an issue with it, this is the best description I could come up with......

Intermittent wub-ing noise, no play in wheel, new bearing fitted, swapped rear discs round with each other, started doing it at over 50mph, and once it's started it does it right through the speed range, getting worse at higher speed, Can feel it through the brake pedal but not through the steering(which leads me to think it's the rear)Just took it into town to check tyre pressures an give it a run, still making the noise an n/s/r alloy is so hot u can bearly touch it, Caliper seems free and so do sliders, feels like the caliper is pulsating, is there an issue with the abs modules on these?

Sorry for the long post and thanks in advance!!

Thats a hard one to figure out. posibly change that caliper and have the brake fluid flushed.

Had it in at a garage as I haven't the time to get too indepth, £170 and 3 n half hours later of test drives and playing with the caliper we are none the wiser, although it's not done it since
