507AX

I had this issue! Took it to the dealer, and the retorqued some things and it went away. Mine was on front though. Sounded identical.

And my 507 just started doing this as well...........same thing. 3000 miles.

They tried that with mine and it lasted for an hour or so.

Everything still good?

Mine is scheduled for rotors, which is nice to get new ones, but not if it means still having the noise. It is so loud right now that I avoid crowds and right turns if possible. I will go left in a parking lot until I find a spot to park.

Last night I went to a charity function and thank God as I pulled up to the masses outside in my glistening 507 that I had to veer left. If I had to go right I may have just kept going!

WESLEY KAY

Wow....that's loud! Yeah something is going on with these 507s from the factory. Something isn't torqued down correctly, or something. There are not that many 507s out there, and now all of a sudden you have a post full of the same problem from multiple buyers. Thank God for the warranty!

Still no noises on right turns, after bringing it to MB. Knock on wood...

Now I am just waiting for my Mode Carbon pieces

coladin

Just got mine back. they swapped rotors from right to left, I think serviced the pads and the noise is gone although I am not sure why keeping a possibly defective rotor that they move it to the other side. They did order new rotors but wanted to try this first.

Hopefully it lasts...

Xstatic

Good to hear, mine is still click free.

JRHolt

Glad to hear you got the noise fixed

Sorry to get off topic here for a minute but which Mode Carbon pieces did you order? Just curious because I just purchased a used 2014 C63 AMG Coupe Edition 507 with the Mode Carbon Diffuser and had serious fitment problems concerning the tabs used to secure the diffuser to the lower center brackets.

Spent a couple of hours tonight creating brackets to secure the diffuser because of the poor design of the mounting tabs

Xstatic

I purchased the following:

. OEM Front Lip Replacement
. P31 Rear Diffuser
. Sedan Bootlid Spoiler

What did you end up getting from Mode Carbon that was giving you probs?

JRHolt

Xstatic,

I sent you a PM

Xstatic

Thanks JRHolt. All I can do is sigh...

JRHolt

You are welcome

Hopefully you won't have any of those problems

Hi all,


I had the same issue happen to me this morning. I was in a parking garage turning left and all of a sudden heard the tick tick tick tick tick tick sound going around the ramps. I thought back to this thread, called a local dealer here in Boston (here for business this week), explained the situation, tech found the same problem as Xstatic:


Found clicking to be the front caliper pins and spring clip shifting. Removed the pins and clips found markings from the shifting, cleaned and lubed the pins. Reassembled and drove again, the noise was gone.


The noise is gone for now. Hopefully, this is not an issue for anyone else.

The sound is a known issue and MB has a " LI " that has been sent to dealers when this problem is diagnosed.

In my case my dealer took photos and a sound byte and sent them to MBUSA.

The LI number I show on my service record is below
5448 LI40.10-P-059248.

I was told that the noise was from part of the wheel and brake disc contact.
The LI from MB USA instructs the dealer tech to use 80 grit sand paper and sand off " burrs " that would make contact with the brake "disc".

The noise is now gone and I do not see any signs of wear on any of the front brake rotors.

Hope this helps and if this has been previously posted please excuse this reply.

I brought my 507 in last week for this same issue. They did the same exact thing. All fixed and no signs of damage or wear. They opened a new case with MBUSA on this last week. They sent in a video/audio clip of it as well.

Bardman

Thanks for the post guys, I have the same problem, but its not very loud and its very intermittent, so have not done anything about it. Will book in to get this fixed!

Ruff507

Sound is back and they opened a new case with
MB. Dealer sent a sound and video clip for evaluation.
I will mention the caliper pins today.

Interesting thread...I have also had this problem, but intermittently. Always when backing out of the garage and then turning right while still in reverse.

WESLEY KAY

Yeah my tic is back as well. Not nearly as bad, maybe at about a 30% level. It was really bad before. I'll ignore for now, but still....

the_indian_kid

I have the same noise to the right. I asked the dealer and apparently because of our high performance brake set up, according to the benz mechanic.. sure.

izzy63

Hmm mine was cus of the parking brake and after i took it to the dealer there seems to be no sound although i do hear it sometimes... could be overthinking but mine is a p31 so might be different issue then the 507 guys

chris135b

Yep, this is what eventually resolved it for me. The head foreman called MBUSA and basically asked "WTF, your fix is not resolving the problem." We ended up getting the bulletin the same day I brought the car into the dealer.

Not sure if this is what you all are experiencing, but this is what's happening with my car.

unagi1

Both of these are intermittent...could be either one. If this gets worse on my car, I'd have it checked for both bulletins.
