Hdlmp cornering currently unavailable ошибка

I have a 2004 E 320 T CDI Avantgarde. A few weeks ago I recieved this error message in the display. It comes and goes, but now it seems more constant.

I took the car to a MB Garage, and the did a diagnostic search. The result was a big «F», and they told me that I have to replace the whole headlight.

Do any of you have some experience whit this. Do i really have to replace the whole headlight, or is it possible to repair this in a less expensive way? A new headlight and labor will cost me apx 1800 Euro.

Apreciate for all kind of help!

(hope you understand what i`m writing, my english isn`t very good)

E 320 T CDI Avantgarde, 2004

Think I will visit a indipendent garage (maybe Bosch?) and let them take a look. Thank you for the advice, seems that MB-Garages is the same all over the Globe — «replace it, even if it costs a fortune».

There are two types of cornering light one which activates the foglight in the direction you are turning and one which is motorised and moves the beam around the crner. If you had the first type then it isn’t likely to be a new head light but if you have the second type then it could be a new headlight unless a local independent is able to get to what the exact problem is. MB will always just «bin it» and put a new unit in even if the repair is quite simple. HTH.

It looks like we are talking about a 2004 E-class so the active headlights are just that. The foglights do not work in synch.

But, if it`s just the cornering function that its broken, my question is; do i really need that? Ok, it gives better light, but is it worth it?

I suppose that the auto up and down still working, since my headlight isn`t turning down to the ground yet. And this is the most important thing, or what?

Then again, I find it annoying to recieve this error message every time I start and stop my car, is it possible to disconnect anything so that the error message disappear?

It would be a shame to disconnect the active part, but it will definitely NOT effect the illumination area.

I have NO idea if it is possible to disconnect these lights and still have them work!

And then I have a possible stupid question; Is the conering light the same as active Bi-Xenon?

Thanks Glojo — but just to be clear (since my English isn`t very good); you would a accept the error and the error message?

And then I have a possible stupid question; Is the conering light the same as active Bi-Xenon?

On our model E-class….. active headlights are those that turn with the steering so yes to that part of your question.

NO……… I personally would NOT like that continual error message and I personally would want all the options working.

Having said that, only you know you have active headlights. If you disconnect it, clear the error message and prevent this message from re-occurring then who would know?

I’m afraid that most dealers tend to replace parts that are not working, it is too time consuming to investigate, or even attempt a repair. The annoying thing is that this might only be a small piece of plastic that is broken and it might be easily fixed?? It might also be totally broken and be beyond any economical repair?

Your English is excellent and I feel embarrassed at how poor mine is.

Well done and please stick around on this very friendly forum.

Yours sincerely
John

I thought the part number was mentioned somewhere but I could not find it. Anyone with any better memory who knew and posted it? I found another post referring to Inchcape listing this part separately (probably for some other purpose?) but the part number is hiding somewhere.

Perhaps the same part is used for the active Xenon lights for horizontal adjustments?

I have not looked if there would be a version coding option, it may not exists as I assume the motors need to calibrate the current position at every start-up (motors are run to one end and then a known amount backwards, no memory or position sensor/potentiometer is then needed).

It could be an SCN coded feature too but since the cornering fog lights can be turned off (members on the forum have had this done), that must be separately coded, I would not assume the same for the turning lights.

Physically cars up to 06/06 have the CAN bus to the SAM and a specific bus from the SAM to the lights. I believe this is common with the levelling and the turning function, it is not possible to cut a wire to disable the motor. On later models the CAN-bus is connected directly which doesn’t make cutting wires any more feasible.

THe headlamp levelling on my newly installed xenons is a seperate loom. Perhaps if cornering lights on the OP’s car was offered as an option, this may be the same?

After a quick look, the W203 looks pretty different in the sense that the level sensors seem to be wired directly to the xenon head lights (control unit). Perhaps this is because the W203 probably does not need these sensors for other purposes while the W211 would need those for Airmatic.

Ended up putting everything back together and giving up.

Do you know if Bosch engineers look at lighting systems?
….and does anyone have any idea how much cornering Bi-Xenons for the E-class cost?

Had a look on Inchcape and it doesn’t appear to be listed. Reluctant to take it to Merc. Had a battery replaced by Mobilo breakdown 3 mths back and this problem started to appear after that. First intermittently and now permanent.

The lights up and down health check still works but side to side no longer does. MOT’s due in a couple of months and i think the lights off centre which may cause some problems.

Any suggestions would be appreciated.
