I confirmed with MB Canada that the cornering light should be functional with the Bi-Xenon Intelligent light system which does not work on mine. I have to take it to the dealer for diagnostic. It would greatly help if someone could video the cornering lights (from outside the vehicle) to demonstrate how the headlight inside parts move.

For corners its a separate reflecter inside the housing. U can see it there is a small over hang the bulb should be in. My main bixenons do swivel at fairly low speed but never at stop and as u know that's when corner lights work. I will check a 2012 in the lot

You can see the corner light and reflector clearly in this pic I shot:

roger23

May i assume yours do not work either....
I cannot get a straight answer from MB Canada on this issue...

dougiebear

Mine do not turn on a cornering light. My HIDs do swivel etc

mbden

Same here. My corner lights do not work. According to MB Canada they should.

roger23

Everyone seems to be having a problem with their non operative cornering lights....
Where can we get a definitive straight answer ?
How can our problem be resolved ?
Any suggestions ?

dougiebear

AH? AH?
I think our dealer :-)

roger23

My dealer has no logical explanation why they are not working, and cant even say if the bulb and wiring harness are installed in my ML

dougiebear

Wow really,
where ru at Ontario?
Are any of the US MLs having the same problem?

roger23

I have yet to see any post originating from the USA , to confirm whether or not the separate cornering lights, are working in USA spec'd ML's.....

I tried the lights of my 2013 ML-63 in my indoor garage under controlled environment. With or without turn signal, driving or stopping. The headlights swivel noticeably like the W164. But there are no smart (or dumb) cornering lights as described by MB. Not even close. To be fair, the wide spread of the headlights on both sides helps illuminating the corners at distance. Not as close as the W164 which was equipped with a dedicated fog/corner light activated by the turn signal.

Found out the code 6?? Is not even in our builds. Someone messed up or MBC decided to not put them in our 2013s. Maybe someone at MBC presumed it was automatically ordered.
None on the lot have them and I have not talked to any 2012 owners in Canada to varify if they were on last year. 2013 GL missing them too. Seems like new GLK I saw had them. Let's bug MBC gang.

jean7of9

Can you elaborate what is code 6. I have the reflector mentioned by Greg. I assume the bulb is also there. It can be a simple software update.

A call to YYZ: Without having to jeopardize your job or raise eyebrows at MB, can you send your 0.02¢. We need to get to the bottom of this.

dougiebear

Nope. No Bulb didn't open to check for wires. The AMG and 350 and GL no bulb in the 3 on lot

roger23

Can someone check with a knowledgeable MB technician to find out if the wiring harness is actually there or not .... ?
If its not, then we should all give up....
However, if its just a matter of a bulb & / or software, then it may be possible to have them working.....

There's a lot of random comments and misinformation here, so I'm going to try to summarize what you're asking and then I'll try to find out:

The W166 ML with bi-xenons has a cornering light bulb installed in the housing, but it does not illuminate at speeds below 40km/h when the signal light is activated? Is that it?

Note that NAFTA vehicles do not get the Intelligent Lighting System (ILS), which is the Euro lighting system. ILS allows individual dipping of either bulb to account for different driving situations (you can look it up on Daimler's technology site for more info). So don't expect that one beam will be actively higher or lower than the other. You can thank the US Govt for that.

I have the lighting package on my 2012 ML350 which was built in May. I don't really know about the cornering lights or how they are suppose to operate, or even if I have them or not. I bought the lighting package for the automatic high beam diming operation and the field of view capabilities. If there are cornering lights that would be a bonus. The headlights throw a very wide beam but inside that beam is another set of lights that I can see which move with and in the same direction as my steering wheel. This is what you must be calling "cornering lights". These two beams seen within the main beam move in the direction I turn my wheels but not dramatically so. If they are meant to be "cornering" lights, they fail because they do not go outside the field of view of the main lights.

I do not make a turn when the main lights automatically move to high beam because when they do that I am moving too fast to make a turn. In order to slow down and make an actual corner turn the low beams automatically come on as high beams are disabled at slow speeds. It is only at these slow speeds that the turn can actually be made and the two lights moving with the steering wheel can then be seen.

All this may seem hard to follow but in simple terms, in my case at least, the lights that I think are considered "cornering lights" are separate lights that move within the main headlight beams themselves and that movement is dictated by the direction of the steering wheel. However, they do not illuminate or move outside or beyond the lighting of the main headlight beams. They are a light within a light. I really don't know how else to say it.

Yes, from my post #2:
Active:
- if you are driving at speeds below 25 mph (40 km/h) and the turn signal is activated or the steering wheel is turned.
- if you are driving at speeds between 25 mph and 45 mph (40 km/h and 70 km/h) and turn the steering wheel.

My 2012 does not function under those conditions, and it sounds like others' in both US and Canada are not operable.

This is from the 2013 owner's manual:

dougiebear

Short! The lights that move are the BiXenons.
They act as high and low beam so I guess your corners work they are the lower light with a reflector.
YYZ! NO BULB :-)

roger23

YYZ, as per the illustration from the ML's owners manual which GregW posted, i am still unsure why the ML's cornering lamps are inoperative....
The bi xenon housings look identical to the bi xenons in my 2010 E550, which do have a separate bulb being illuminated, if the turn signal is on, at slower speeds, turning into a driveway etc.
According to the ML's manual, this feature also supposed to be standard with the ML's bi-xenons.....
I do understand the LED's replacing fog lamps in the front fascia, but whats the story on the cornering lights omission ?
Is the wiring harness there, and only bulbs are required ?

YYZ-E55

The word I got was that the cornering lights were not certified for US/Canada - clearly the owners manual was adapted from Europe and this aspect was overlooked. I have no idea with respect to the wiring and whether or not the functionality can be retrofitted.

GregW / Oregon

That's extremely disappointing, and not what I was lead to believe when I ordered. The W164 had functioning cornering lights in NA from Day 1. I would like to find a way to push on this issue.
