check front right parking light warning..
 

I got this check front right parking light warning the other day and because I was late for a meeting, I decided to check it out afterward..
However, when I re-start the car after the meeting, the msg has disappeared and both bulbs on the front right parking lights were working..

Today, the error msg appeared again and I was able to verify one of the front right parking light is indeed out..however, the warning msg disappeared and both bulbs were working again after I drove back from autozone and was ready to replace the bulb..

What do you guys think? Simply a bulb problem or is it possible a more serious electrical problem?

I just had the same exact issue. I thought I was going crazy.

that happened to me before too, but the car went in for service and it never happened again.

parking lights only turn on when its dark out. so the reason the msg came on is because it was dusk or night, then the next day the lights didn't turn on due to daylight, therefore no trigger of the obc.

you guys don't notice your lights change when you pull into your garage?

/thread

This happened to me when I had the LEDs installed, replaced them with Polarg M4 and it never happened again.

if you read my post more closely, you will see that I mentioned only 1 of the 2 bulbs on the right side was out when the error msg showed up, then after re-start, both bulbs are working and error msg gone..

I think is a problem of imperfect electric contact on bulb contacts.

I had a tail light go out a couple of days ago. Actually the warning called it the right brake light.

Also a little surprised that the driver's side is the right side.

I get the right front parking light message also. When I get out of the car to check it, sure enough 1 of the eyelid bulbs is not working, but if I bang on the light with my hand, then the light comes back on.

So does it just sound like the bulb is not making good contact with the socket?

I took it to the dealership and of course it was not giving the error message at the time and the lights were all working, so they said that they cant do anything about it unless they see the error message and the bulb not working.

I get this error message almost every morning when I start my car to go to work because its still dark out.

i get the same thing too
1 bulb sometimes go on and some times don't i am seriously hoping it is the bulb not the car

Well, I have an appointment this Saturday at the dealership to get all my lug nuts replaced under warranty since they are all rusting.

Hopefully I will get the parking light error message while I'm there and they can look at it.

Went to the dealership today and got my bulb replaced in the right front parking light. The message just happened to be on when it was there, so they could see for themselves that I was not crazy.

They replaced the bulb and it has not happened since.........but its only been 6 hours.

They also replaced all my lug nuts on the entire car because they were all rusted. Covered under warranty.

Im having the exact same issue with my c350, did you guys ever find out what the source of the problem was? thank you

Its just because the bulb may be a little loose or maybe there's some corrosion on the terminals. Also it could be a bulb on it's way out, I remember mine was sporadically on and off and then it went off for good, once i replaced it, it was fine. Interesting thing is when the message is up and the car knows that bulb is out, it cuts the voltage to the bulb, so you have to cycle the ignition once the new ones back in.

yup! had that message b4, but it's usually one of the two bulbs that goes bad located in eyebrow of the headlights....

I took my car to the dealership and they changed the bulb, however the problem still remains... Like the original poster of this thread said this is an intermittent problem meaning that sometimes the msg appears and when I check, one of the bulbs on the front right parking lights is out but some other times the msg disappeared and both bulbs on the front right parking lights work.

My warranty is about to end so I definitely want to get this fixed before it runs out. I know it is difficult for the dealer to find what the problem is because when I take my car in the msg doesn't appear.

I had this problem maybe 2 months ago. The warning for the left parking light kept going on and off, but now the warning doesn't pop up and it hasn't been on for the past 2 months.. My left brake light did burn out soon after though. Maybe they're related?

Is there a way to "reset" this warning or turn it off? Mine has been on for a while now. I know pressing the ok cancels it but just wondering if it's a way to actually turn it off completely BEFORE I get a chance to swap the bulb out

Are you guys still having this problem. My right eyebrow just began doing this.

Hey there - so you replaced the OEWM parking bulbs with Polarg M4's and these are good to go? LED's? No computer errors? Thanks.

I have an '08 E350.

Anyone figure out the issue with this? I had same message come up right after I did a car wash and when I checked it 10 min later indeed one of 2 lights was out but the message doesn't always come up, just did some search and it's the wy5w bulb blue color, do I need ones from dealer to not have any errors or the sylvania ones will do?
Thanks

Polarg m4 work if you want a bluish/purplish hue. Non-dealer non-oem bulbs work as well without throwing errors if they are the same type. If you want to switch to LEDs you have to find specific ones which will not throw error codes. AZNoptics sells them here. Search "c300 eyebrow lights" and you will find tons of information on your options.

Thanks for the reply I just picked up the sylvania 2825 long life bulbs I am going to give these a try hopefully no errors or brightness difference :)

I have Polarg M4s in my W204 Sport to match the bi-xenons. The same thing happens to me on occasions whereby I get a bulb failure warning that is actually the case on checking. After switching off and restarting the fault corrects itself, the bulb works and message goes away. And yes I have noticed how the light intensity varies depending on the ambient light around the car. Have a more serious issue now - one of the bi-xenon bulbs has failed, after 2 weeks of having changed from white to pink! Not an easy fit. :zoom:

Oh wow yeah same exact thing just happened now, so I go to pull out old bulb to replace it with the sylvania ones and before swap light was off I remove and it didn't look burned and reconnect and it worked so I placed original one back on and message went away then few min later I drove off and the message pops up again �� I go out and look and light is off lol can anyone explain this craziness :) ?

Sounds like a contact issue or a failing bulb, they're easy enough to replace. Make sure the bulb's nice and tight in the connector and well sealed. Could be the wiring as it can bounce around, maybe a chaffed wire? I doubt itd be a control module as other lights would most likely have issues as well. If the control module sees a fluctuation in power it'll drop voltage to the bulb and illuminate the message. A key cycle will clear the message unless the issue still remains, ie open circuit/short

Thanks I am pretty sure I secured it tight in the bulb socket, I'll give it some time and see if it resets because first few tries code still came up but last night it didn't so hopefully it went away. I'll keep everyone updated

Oh how I hate this problem - I haven't seen this on my C250, but my W203 C240 encounters this problem despite the bulbs being good. I just open it up, clean off the bulb contacts, and re-seat the bulb securely. I haven't seen it in a while, but I know how annoying it feels.

Check front right parking light warning
 

Had same message/problem, passenger side parking standing light out.

Replaced with new Sylvania bulb, did not fix. Took bulb out, sprayed socket with electronic tuner cleaner, carefully pulled the bulb prongs slightly away from bulb and put back in socket. Problem fixed.

Hope this helps.

so has any one solved this or do we just carry on turning every thing off and on again.

The eyebrow/parking bulbs are really touchy and tempermental, partially because of the heat buildup in their housings. Causes the stock incandescent (and sometimes even LED replacements..) to burn out more quickly than normal.

I've also noticed that error messages can pop up for the parking/sidemarker bulbs because of the way they're wired. The parking bulb can go out/error out because of an issue with the adjacent sidemarker bulb (I believe the outer eyebrow bulb is the "sidemarker" one), voltage and current measurements in the front SAM unit detect an "error" and will power off the "failing" bulb until the car is powered off and started up again. It's very annoying and finicky. Sometimes you can replace a dead bulb and it still won't turn on until you've left the car off for a bit.

So far I've only found two solutions to this

1. Replace both bulbs at the same time, or all four (both sides)
2. Variant coding tweaks + optional LED bulb upgrade. I've turned off PWM clocking and disabled the "open load recognition" parameters so the bulbs will always light up until they are truly dead. I'd probably not do this tweak with standard incandescent bulbs though, if anything goes wrong and they heat up a lot, they can partially melt the bulb housing. Another thing I did for the LED bulbs was lowered the voltage regulation from 13.2 volts to 12V, LED bulbs are happy with 12V anyway, and I assume the lower voltage/current output will reduce heat in the housing as well.

The eyebrow bulbs were a constant source of irritation until I figured this out, I was going through incandescent AND LED bulbs almost every two months..

Just remember, switching the car on and off (pull out key) will reset the bulb error, until next error trigger.

I use leds in my c300 eyelids and this happens (sometimes) when they are old and start to burn out. (also, winter makes old leds cry. Use better solder my china peeps? :nix:)

Thank you very helpful, will try tomorrow in day light.

Dear gents, I have similar issue. I have error message on dashboard display that parking bulb is faulty. I have changed two pieces but issue is still persisting. Does anybody idea what can be solution? Thanks. Regards, andy

The insulation on the wiring feeding these lights has probably deteriorated and completely fallen off the wire. The wires are coming in contact with each other causing a short. I don't know who designed the wiring, but they should be shot. If it's the outside bulb (there are two on each side) it could affect the turn signal on that side. I've been dealing with this for the past week, and discovered that if I pull the parking light bulb out of the socket and ensure the wires are not touching, the turn signal worked without fail. I did get some liquid electrical tape, and covered the wires as best I could, and haven't had a problem yet (although is has only been 1 day).

Before you do anything check the insulation on the wires.

My passenger side parking light was getting this message so I swapped in an LED bulb and its no longer turning on. I tested it on the driver side and it works fine. Could I have messed up the wires when I pulled out the socket? I tried cycling it but it still doesn't turn on. Does someone know what it could be? Thanks

How did you manage to do all of this? Thru the Star?

How did you make the coding tweeks to keep your lights on?

What variant coding tweaks? Sorry I'm not tech savvy
