I just noticed this the other day and I was wondering if anyone else has had this problem and what the solution was.

My C is an 08 so it has the folding mirrors feature, and you can have the car fold the mirrors when the vehicle is armed. Well a couple days ago, I noticed the mirrors weren't folding after the vehicle was armed. I tested the folding mechanism by pressing the fold button and they operated as designed. I checked the menu to make sure that the mirror folding feature was enabled.

Any ideas?

You have done all you can do so if the car is still in warranty you should consult a dealer.

That's the issue, I'm way beyond the warranty period and I don't want to deal with the stealership.

I wonder if my recent changing the batteries in my remote may have affected the way the car operates. Or if there is a secret sequence of remote buttons may have turned off the feature. I will see if using the other key makes any difference.

RLE

The remote batteries are not involved. If the remote locks and unlocks the doors normally then they are OK because that's their only function.

Do both mirrors no longer fold or just one side

My car has gremlins lurking, miraculously they started working again over the weekend. Wierd.... the only conclusion I can make is, its german electronics.

I am having the same problem, mirrors will not fold in...started a couple of weeks ago?
Also since day 1 there has been an interesting noise when you unlock and enter car it sounds like a fax machine like sound coming from drivers side mirror area?? it is not consistent and lasts for 2-5 seconds usually.

Any thoughts.

sounds made are why they were discontinued after 2008... too many comoplaints and a major design flaw that allows moisture to collect in the joint and cause a constant creaking noise when unfolded from time to time..

had my dealer 'fix' this issue three times... finally, the third time there was a latest TSB that called for the "drilling" of holes in the joint and a special remedy with lubrication to be applied, not sure of exact details check with ur dealer the tsbs...

after that third tsb fix, they made a hard change to the hardware... problem solved ever since

My 2012 C300 has this feature, should I disable it from now on?

Not yet Mine are still working on my 2010, but I had to have one replaced, it was making funny noises, a $500+ bill paid for by MB.

I have the SAME EXACT issues! I took it to the dealership and they could not dulpicate the sounds. My warr expires in a few days too

They said they "Noted" it and if I have the issue after my warr period they will still get it covered (assuming I can duplicate it for them)

They do both - creak from the plastic rubbing when opening and closing AND wine from the drivers mirror sometimes when getting in the car (mirror opening after disarming)

There is a TSB out for the auot fold mirrors, if you complain, please tell them to check for the TSB so they can fix this for you under warr, I would hate to see you have to pay out of pocket.


Also OP it may suck but if you go to the dealer they charge usually a 50 dollar or more diag fee to see whats wrong, and when they discover whats wrong if you fix it, they will apply the diag fee as a credit toward the service repair.

My 2009 c300 4matic is having problems with folding mirrors again.
When I disarm the car and enter vehicle there is a strange squeal noise coming from the mirrors...it is similar to the sound you get from a fax machine.
It also has the rubbing noise but that does not concern me.
I am worried the fax like noise is a warning of further problems?

And of course the dealer can't duplicate sound.

Any idea's

RLE

Well, check under the mirror for an incoming fax, then.

Beancooker

I have the exact same sound. It happens 90% of the time. It only happens after the mirror has folded out and is in the correct position. Then I start looking for the fax...

slowhatch

Pardon my newbness but how do you make the mirrors fold with the remote? Ie.during lock and unlocking?

Domm

It's somewhere in your instrument cluster (speedometer screen). Press the left or right arrow to go through the options and enable it. Sorry for not having specifics, but I don't memorize every step

slowhatch

Ok will take a look, thanks!

Regarding the noise, my mirrors used to make the sound but MB fixed it under warranty with no problem. My issue is that when I press the lock button on my key, the mirrors actually unfold instead of fold, whereas its supposed to be the opposite. I don't know if this is an errors from my end or a bug.

The automatic fold feature is "enabled", but when the car is turned off they don't fold, so I manually fold them and when I get out and lock the doors, it unfolds.

Can you help?

Hello,
I need help to get the type of problem I am having.
Usually when I lock my c300 using remote the car used to make beep, lock and the mirror folds. And when unlocking it opens while mirror unfold on opening one of the the front door.
Few days ago, the sound stopped and the mirrors stopped folding and unfolding on opening the door, yet the door locked properly and unlocked on remote instruction.
Morover, it seems no problem with The mirror as they still fold and unfold on manual key located in the dashbord.
Can anybody please direct me to the problem? Is it a fuse problem? Which number and where it is located?
Thanks a million in advance.

You have folding mirrors on a 2012? They must be custom, did you install them? Maybe something failed in the motor. It should still beep though.

Prago

He may be in Canada. They had that feature available if I recall correctly.

Eliechedis

No it is not customised. I get it straight from official dealer same year of manufacturing.
Also, I don't think there is a problem with the motor, as I early stated the mirrorsame still folds and unfold from the manual button located by the LHS of the steering whee.

Can you still help?
BTW, I am in Lebanon.

It's a bug in the software. You have to go into the convenience settings and cycle the setting to disabled and enable it again. Good luck!

My 2012 in Canada has the folding mirrors they work great, no weird noises coming from them.

When winter hits I make sure to turn the feature off so the ice doesn't freeze them shut hahaha.

knock on wood I don't have issues with them in the future, I do like the feature but if a problem occurs ill probably just turn the feature off. (I'm off warranty for everything but the trans and engine).
