Hello all,

My E220D 2016 is suffering from an extremely annoying and mind boggling noise coming from passenger side front wheel (i know this because it is louder with passenger window open)

I just need to understand what it could be, or if anyone has had this issue before as NO MECHANIC CAN TELL ME WHAT IT IS!! However I know that none of them have tried to take the caliper and brake assembly off, only looked at everything visually.

When im coasting or driving along the noise becomes apparent after a few minutes, it progressively gets louder with more heat, it also comes up when im turning the wheel right ever so slightly and goes when i turn back left, when i press the brakes i get another noise that’s different to the inital coasting noise which makes me believe it cant be due to braking!?!? I feel like even when theres some cornering pressure to the left of the car the noise becomes apparent as well

Ive recently had my back caliper changed due to sticking and all my discs and pads all mercedes.

Im officially about to go crazy as this is just too much now, i just want an answer so i can try and put this to an end :O

In video attached you can hear the noise im talking about FIRST and then a little later you will hear a change on the noise which is me applying brakes.

My discs and caliper where fittes by a friend so maybe theres something he did wrong?!

The noise literally just sounds like a really WEAK and BAD wheel rotating, and I'm pretty sure it isn't the wheel bearings.

I did today go to another mechanic who found a tiny bit of play in my wishbone (arm) on the left but he said this wouldn't make the rolling squealing noise I'm showing him.

Have you checked carefully between the stone guard and the disc to see if there is a small stone trapped in the gap.
Sounds to me like something rubbing against the disc as it rotates.

Yeah definitely nothing there
 
Does it go away if you apply a very light pressure to the brake whilst driving , and does the noise return if you let the brake pressure off ?

Yes when i apply any kind of pressure, and yes it comes back when pressure is off
 
Not knowing what type of calipers you have on the car but is the anti rattle shim for the pads located properly ?

Not sure what a rattle shim is to be honest, but ill have a search now, these are basically the calipers, not sure if that helps :x

Ok i see now, from what ive seen they look fine, but then again i wouldnt know unless its all taken apart? Im not exactly too clued up with the details of how parts should be, You think its worth paying someone to put it all back together? Or maybe i should just purchase some new ones?
 
Ask your friend if he put copper grease on shims and edge of pads, it could be that sticking

I would have a look yourself , easy to see if it is broken or if fitted wrongly - Google pics for reference or compare with the drivers side.

You may be able to see it , using a mirror , with the wheel still fitted depending on how much clearance you have.

I was there with him and i myself put silicon grease I believe (white paste) on back of pads and that was all we did?
 
That's definitely a metal on metal sound. What's the end float on the front bearing like on that side compared to the drivers side?- You might need both front calipers off again to test this with a gauge?

here's the same thing with a dial gauge on a W124. YOURS MAY BE DIFFERENT!
