2010 S212 E250CDI headlight fault

[AW8]

Hi folks,

A very good friend of mine runs a 2010 E250CDI Avantgarde (PRE-Facelift S212)

VIN WDD2122032A270934

I have accessed his data card from using VIN

It has lamp spec as follows...........

600 HEADLAMPS - CLEANING EQUIPMENT
608 AUTOMATIC HIGH BEAM SWITCH (IHC)
619 CORNERING ILLUMINATION
621 HEADLAMP WITH ILS, LEFT-HAND TRAFFIC

He has message on dash that says "adaptive lights not working" & he reports no dip or main beam to nearside.

My immediate thoughts were failed ballast. I am aware aftermarket or used ballasts are available. I have also seen posts indicating that coding may be required.

Annoyingly I cant seem to access a working online parts finder. The link below gives an error message "uncomment: mysqli_conn line 86" when I try to access relevant section (54).
Mercedes-Benz EPC. E 212.203 , E STATION WAGON, Market Europe, North America, Japan.

I am a little bemused when reading up on matters........

I have seen online content indicating 2 bulbs for dip and main but also seen other content indicating some cars have one bulb with a metal shutter to adjust beam.

Q1 : Any ideas other than Ballast or control module failure (new headlamp circa £800) ?

Q2 : Any recommendations for a decent aftermarket ballast supplier ?

Q3 : Other than checking connections/fuses any (safe) d.i.y. diagnostic/fix advice ?

Q4 : Is MB/Star diagnostic required ?

Answers to 1-4 above & any advice or thoughts appreciated.

Still relatively new to MB & I confess to not being that clued up on vehicle electrics.



Thanks in advance

Not that this makes much difference, but to clarify....It is the offside headlight that is the issue not nearside as prior stated.

 

[MrGreedy]

Is there or has there been any signs of moisture inside the headlight?

 

[AW8]

He says not

Breaking news............It needed a bulb change.

 

[MrGreedy]

Well, not all fixes for a Merc need to be expensive. Glad it's sorted .

 

[AW8]

I guess so.....albeit £94 for a bulb change not bargain of the week.

Hi,
Not that it matters now but I had adaptive headlights not working warning and a new bulb to replace the pinkish one fixed it.
My appeals and research referred to faulty windscreen sensor/camera or ballasts but a relief it was just a bulb. I went crazy and bought two.
It's a pity the wheel arch liner needs removal to access.
Although I remember an A3 i think it was that needed bumper off to replace a bulb.
Anyway, I am glad your friend is sorted.
Kindliest regurgitations,
