New member to the group and looking for help on my e350 2011

[Maxamo26]

Hi guys I have come across this page and decided to join. I purchased a e350 v6 cdi 2011 at the start of the year and I have really enjoyed it. Recently my drivers dipped light went out so I replaced the bulb nothing happened. So I decided to use the left hand side bulb just to see if that may work and again nothing. In between this the light did come on on the original bulb for around 10 seconds and hasn’t been on since. I did some re search and purchased a headlight control modual to see if that was the issue but again nothing. I have had a scanner put onto the car and have been told there is no voltage going to it now the guy who did this didn’t really seem to care or know what he was doing has anyone els had this issue and will I be looking into getting a new light anything is a big help thanks guys

Hello and Welcome,

Do you have bi-xenon headlights? Ballast failed?

Check the fuse.

Hi the mechanic said he checked all the fuses they seemed to be okay and yes bi xenon when you say the ballest do you mean the light if so the lights okay

Hi Maxamo,
I hope I can help, I’d run through a logical elimination process.

1. Is the switch working, I’d say yes as the other one is working and it’s on the same circuit and that would also apply to the fuse.

2.The ballast unit would be my next place to look, it is basically an inline resistor that serves two purposes it helps with the initial arc to get the hid working and also limits the current that the lamp can pull to prevent it burning out.
So you have said you have replaced it, it is critical that it’s replaced with the correct ballast/hid controller. I would be checking that there was 12v going on the input side and 12v coming out.

3. If there isn’t any voltage on the input, then look closely at the wiring, is there any corrosion on the earth/negative? Or any of the wires for that matter.

4.Does the loom look in good condition? Ie not pinched or squashed?

5.Check your common earth point for corrosion this location will differ on each vehicle it’s usually under the bonnet near the front top strut mounts.

Hi thank you for taking the time to give me a detailed reply I really Appreciate it. The mechanic did say that there was no earth going to it but he didn’t specify which particular part just said it I may looking into purchasing a new loom and trying that possibly see if that may help

Ballast units are a common failure. It's a metal box screwed to the underside of the headlamp. It's common for condensation to form inside the lamp. It condenses back into water and runs to the lowest point of the lamp, the ballast unit. It gets inside and damages the sensitive electrics. If you investigate and find water damage I'd recommend you don't just fit a new unit before investigating the water ingress. It'll fail again in short order if water is getting in.

I purchased a new unit as shown above and fitted and was still not working I will be selling the car at the end of this year and need to get this light sorted ASAP if possible

I’d also unwrap that black electrical tape, it’s possible someone has done a poor join/splice on one of the cores.
On the brown and green cores, that is a diy wiring attempt.

Oh no I have a feeling this is going to cost a lot haha

 

[Maxamo26]

Does anyone no what this symbol means also ever since I bought the car it’s been there and cannot seem to find anywhere what it means

Is it a key fob, battery problem ??

 

[Maxamo26]

I’m really not too sure the key works fine

Both keys ?

 

[Maxamo26]

I havnt checked the other key I can’t remember if it came with another key I’ll check when I get home after work and put that in the ignition and see if anything comes up

 

[Maxamo26]

The symbol on the dash was to alert me of the speed limit on the roads haha so that’s one problem solved just need to sort this light out do the headlight control moduel need to be coded in at all
