Vibration is mainly when I brake rather lightly.

It got worse and worse during a (2 day) trip of 1000km last week.

I'm thinking a disc that's bending more and more...?

I've got an appointment tomorrow (for dash rattle) and
will mention this too, but did anyone here experience similar?

First thing to check is wheel balance and alignment. If those are ok then worry about "warping". In my limited expirience MBs are not very prone to rotor issues. Hondas are the worst in that area.

Non AMG/Avantgarde brake discs (the smaller ones) are apparently prone to warping especially if you have and use drive pilot/adaptive cruise control; I've seen some reports here a seem to remember seeing a recall/service issue about it.

I've got drive pilot and the bigger front brakes and am getting slight vibration, especially with the lighter brake forces drive pilot use to maintain distances.

Egonvdv

thanks for the replies. I had to look up "warping" as had never hear of this term :-)
I too have drive pilot. wil pass on the info to the dealer tomorrow
To be continued!


EDIT:

found the issue in the Bulletin thread:

LI42.10-P-066910 AUG17 – 213 without AMG juddering/shuddering of the brakes at the front axle can be felt when braking, check the wheel assembly components – disc brake & brake pad condition, wheel imbalance, suspension & steering parts, and wheel hub contact surface. If none of the components are visibly or measurably damaged replace brake pads.

dealer could not find the file with am number, but did find similar cases which suggest to change discs.
will have to come back as they are not in stock. TBC...

See attachment.

Seems like a perfectly smart approach.

Egonvdv

Sorry, completely forgot to follow up: Front discs were changed and all is well again.
though seems to me, that the problem will return at some point...? or a the discs different/better quality...?

Hi, you've got the non AMG line brakes yes? And they replaced them for free? I'm being told I need to pay £280 to replace my AMG line front brakes as Mercedes will only offer a 50% "goodwill" discount. What country are you in, I'm trying to get evidence of this issue to fight back for a tree l free replacement as I, like you, suspect the issue will come back through no fault of my own.

Egonvdv

yes non amg
under warranty
France

konigstiger posted a bulletin here above so to me this means it SHOULD be free.

Proeliator2001

I agree it should be free for non AMG brakes. Another user had their AMG brakes replaced for free in Italy. Must just be the UK Mercedes office that is tight fisted!

Egonvdv

i think the problem is returning :-(

bellavance

Deleted. Sorry ...

Egonvdv

but i did read it :-)
funny, i do know it's "brake", no idea why i wrote "break" all over that post :-)

bellavance

Same thing could happen to me ... I'm French speaking.

;-)

Egonvdv

Does anyone know of a real solution for this? Changing the discs only solves it for a few months...

ABill

I will follow this.
My car is in for this problem and will have new discs shortly. Will be interesting to see if the issue re-occure...
And yes. Non AMG. Change for free...

Egonvdv

yesterday dealer changed front discs (again) but this did not solve the problem,
so they ordered rear discs which arrived & were mounted today.

He told me it's a very particular way to mount these discs and that they
made a point of following the instructions to the letter... (whatever that may mean...)

For now the problem is solved again.... but I have little faith that it will be solved permanently ..

Proeliator2001

Mercedes UK customer support are claiming there are no issues with brakes on my model and will not budge on the 50% 'goodwill' payment. They deny issues with drive pilot braking and wouldn't comment on standard brakes bring replaced for free either.

That's the last straw for me. Selling this tub of crap and will never touch Mercedes again.

Egonvdv

How can they claim this when there's a bulletin about it????? (see konigster's post above) - print it out and show it to them..?

ABill

I agree!
I had a check "GALA" and they changed the brakes without a word!
There is one thing and that is that the anomaly needs to be above some values... According to the service report at least...
Check with a diffrent MB service for a second opinion?

Proeliator2001

I wasn't checking with a dealer's service department. That was directly with MB UK customer support!

They claim there is no identifed brake problem on my model which I take to mean the AMG line brakes. I said the standard brakes are suffering and they were careful not to confirm that.

Total BS response after months of niggles and issues that they are acting like flat earthers and denying the obvious. I've seen in UK forums that no end of W205 c class owners , Inc those with AMG line brakes, are suffering issues. I just find it disgusting customer service and that's why I'll vote with my feet and take business elsewhere.

Just curious as this warped rotor issue has been around for many years in all brands. For many years we have resurfaced the rotors lightly taking off just enough material to obtain a true condition then put a non directional finish on the rotor surface and reinstall after washing the rotor. Lasts for quite a number of miles. I believe I understand why a non-AMG is more trouble prone if P-3 equipped and used on a high speed highway as the system as I understand it does use much light braking which builds up heat on the smaller non-AMG front rotors.

Egonvdv

This is my 4th new Mercedes and 1st time I have this problem. (had each car for 3 years)
But as this is my 1st MB with adaptive cruise, to me it seems logical that that's what's causing it...

robert c

Agreed
Just noticed and read your avatar I am a big fan of the Rolling Stones since 1962. I still remember seeing them in Greensboro NC in 1965 Worlds greatest rock and roll band period.
