2012 e350
Hey everyone!
Just picked up a white E350 coupe today and I am loving it! Just a quick question.. My LED lights on the front bumper do not turn on at night with my headlights.. but they do turn on when the car is off and the key is still in the ignition... Any ideas?

When the engine is switched off and ignition is on, have a look on the vehicle settings using the controls on the steering wheel, should be on there and you'll be able to enable the DRL LEDs. They will be dimmer at night anyway (or when the headlights are switched on).
Hope that helps.

i did that.. its not at all.. took it the dealer and they said they fixed it.. still doesnt work.. do the leds turn on with the headlights if you turn the light switch to on instead of automatic at any time of the day? i hope that makes sense.. it seems like i have to take it back.. i turned on all the settings from the light section from the steering wheel.. thanks everyone

There's something not quite right there then. My DRLs are set to on so when my lights are set to automatic in the daytime or when there is enough light for the car to not use the headlights the DRLs are on full brightness.
Most the time I have my headlights switched on and the DRLs are on but dimmer than normal, as per my signature pic.
Take the car back and tell them to sort it, express displeasure at having a car that isn't functioning properly considering how much it cost and the brand etc, should get it sorted quicker that way

Honestly I have no idea what the smaller sidelights are, mine is just running the bi-xenon adaptive lights, looked at upgrading the D1S bulbs but I get enough people flashing me at night as it is because they think I drive with high beams on when I'm not.
I'll have a look and see if I can get to the bulbs later on and let you know if I can see what they are.

So if a 2012 E Coupe has P2 Package, will the LEDs and headlights be ON at the same time? Anyone can confirm?
Thanks!

2012 E350 Coupe
Link to my 2012 E350 Coupe with P2 package pictures.
One picture shows the DRL's at full brightness when the headlights are off.
Another shows the DRL's still on but at reduced brightness when the headlights are on. At night, the DRL's at reduced brightness look somewhat brighter than shown in the picture.
The master lighting switch is in the "A" position and the DRL's were programmed to function this way in the Settings menu.
Quite surprising this cannot be done with P1.

E350 coupe
Website says they should with P1 package, but mine don't either
It's crystal clear on Mercedes' website that the LED lights should be one whenever the car is on AND that this is a standard feature (P1 or p1). I'm pretty upset that my LED lights are not turning on. Can anyone tell me a reason for this discrepancy? I read the website at least 50 times to be sure they were included before buying the car, so I am pretty upset and plan on taking it up with Mercedes.
This taken right from their site under standard options:
LED Daytime Running Lamps
Bright white LED Daytime Running Lamps help increase the visibility of your vehicle to oncoming traffic by illuminating front lights whenever the car is switched on. With long life and low energy consumption, the light-emitting diode (LED) lamps also add a distinctive high-tech styling touch.

Next to your main light switch on the left, their is a small button with a headlight push that in and your DL's should stay on. If the icon shows in your clock that means the DL's will only work during the day.

E350 coupe
I've finally got the correct answer to this forum's problem! On the E350 Coupe, the LED lights only go on in the daylight. They never go on at night or in dark areas (i.e. a garage). There is no way to turn them on at night, which is different from the E-class sedans, which have a different lighting system altogether.
I took the car into the dealer. Three different front-desk servicemen looked at the car and couldn't figure it out. Finally, once it had been in the shop, a smirking mechanic came over to me and showed us all what idiots we were. He got a pretty good kick out of the befuddled servicemen.

2013 C63 Coupe
Benzman369 is correct. That is the difference with the P1 and P2 packages specific to the E coupe. Mine is a 2012 E350 coupe with the P1. I bought the car in Aug 2011, and just to clarify it has the straight DRL'S and not the hockey stick styled ones. Mine does not have any options in the light settings to enable the DRL'S at night. Yes, it's unfortunate these features are not standard and it may seem a nuance to Mercedes designers. But for goodness sake, mercedes Benz dealers and specialist should know this as common knowledge and advise potential buyers! (here's where I begin to rant). Like many of you we are automotive or driving purist, if we weren't we would be driving Toyotas. Drivers should be able to use the DRL's, fog lights on any vehicle for enhanced visibility or to be visible. In the case of the 2012 E350 coupe with on the P1 (so far), drivers cannot enable the DRL'S at night and is triggered by a sensor(s) most likely by software. Mercedes missed the mark on this particular requirement during their design definition for the 2012 E350 coupe. If they did this specifically to differentiate the P2 from the P1, then I am disappointed in their philosophy for two reasons. 1. The lack of standardization. 2. Because their lack to standardize it seems like the DRL'S are there for asthetics reasons and not for the reasons I stated for the driving purist. ie enhanced nighttime viability and to be seen. (end of rant). I hope you're listening Mercedes Benz and come out with a software change.

2010 E350 Coupe, 2010 GL350 Bluetec
Mine is a 2010 with P2. When I first got the car I noticed the hockey DRL went off when the main light was on. Brought it back to the dealer and they fixed it. From memory, it says on the worksheet "...found and loaded program from similar vehicle..."
I read on a Taiwanese forum lately they have the same issue for W204 C Class and W212 E Class with halogen lighting. They also confirmed DRL stays on all the time for the ones with xenon package. The official reply from MB Taiwan is this is a code related issue and they can't do anything about it. However, one owner reported that he has a C Class in China and the dealer there helped to apply an authorization from MB Headquarter Germany. He was informed to bring the car back 3 days after the application. The dealer plugged in the computer, input the authorization (code or number) and the DRL is now on all the time.
Some of the owners have access to Xentry diagnosis DAS and claimed the setting could be easily changed by activating ILS (Intelligent Light System) from within Xentry. Well, they got together this weekend and couldn't make it work. They checked and compared the on board computer of C200s (with ILS and xenon lighting) and C180s (halogen lighting and w/o ILS) and found the part numbers aren't the same.
I'm still confused after reading all of these but it seems MB intentionally doesn't want the DRL to be on when the main light is on, for the ones without ILS (or AFL, Adaptive Front Lighting). The article in the following link seems to touch a little bit of it.

Im gona throw a wrench in this. I came home with a 2012 E350 last week and my lights are set to auto and I can turn my LED DLR's on and off at will. I have a button just to the left of the light dial that allows me to turn the lights on and off.

Hmmm...I don't have an E350 coupe, but I have noticed this on every E coupe in the morning in my neighborhood. When it's dark, I've always wondered why the headlights were on, but not the LED's...Maybe there's a way to change the settings by hooking the car up to the service tablet computer thinks (STAR or XENTRY...I'm forgetting the name) that allows you to change the vehicle parameters?
