Error light dynamic citroen c6 problem

[Disaster189]

Assuming the motor inside the headlamp has not failed, then in the event that the directional function is disabled, it would maintain the height correction function - again as I indicated above: "only the headlamp dynamic height adjustment remains active" - which is the vertical up and down movement to prevent blinding of oncoming traffic.

I really don't understand what you're saying but the vertical height slider doesn't really work at the moment

Ok in simpler terms, if the system detects a fault with either headlamp and in this example above with the ballast, then it means the headlamp goes into backup mode (refuge) where it will maintain the up and down movement (if possible) but will deactivate the left and right directional functionality.

This assumes the motor has not failed entirely and is able to move up and down.

Thank you very much for your help and advice. Really the best thing would be to get a complete left headlight and test it to see if the fault is in the headlight or outside of it, but if it wasn't a problem with the headlight it would be a very expensive and unnecessary investment. I'll keep looking into the problem and see if I can get a headlight last.

Any ideas on this? I had problems with RH lamp and changed it to completely new headlight unit. Now I have "no connection between headlamps" - same as before. I have diagbox and this fault cannot be removed. I think only old LH lamp move up/down when car starts and both lit normally - only directional part does not work and green light is blinking. Somekind of configuration error (car says this)? Related for example to vehicle height settings?

Tried to de-activate and activate turning lights with no luck.

Sounds like the headlamp motor for one side is at fault.

But the old LH headlamp moves and works normally (except turning lights while driving now because error). The new headlamp does not move, only lit.

Are you certain that the new headlight unit is identical to the old unit?

Well it is new original Magneti Marelli (like old one), I think only 1 model ever produced for this car.

Make sure the replacement was from a left hand drive model if your car is LHD. The RHD & LHD headlamps are different.

Are you sure? It was ordered from Europe (LHD) - but the LHD/RHD selection is on software (tried it allready)..

The xenen control ecu inside lamp is same on right and left.

[GiveMeABreak]

Yes, different part numbers for RHD and LHD headlamp units.

[joopajaa]

Hmm I think it is for LHD. BUT - maybe it is without turning option (which is strange since same control ecu). Part 711307022561. If this is wrong, maybe I just take interior parts from my old leaking lamp since the xenon part with turning was fully working.

[GiveMeABreak]

That's not a Citroen Part number, that's a supplier number, so can't confirm.

Each Headlamp unit has its own earth supply, so for the Right Hand Lamp, check earth MC15:



Pop your VIN up for me so I can check the exact car specs (please post your VIN in full without spaces - it will be automatically masked from public view after submitting your post & will only be visible to staff).

[joopajaa]

OK thanks I check this earth MC15. Other number on Magneti lamp box is LPL841. I think OE NO is 6206A1
VIN VF7**************[VIN obfuscated, can be read by forum staff] - its an Exclusive with almost equipment.

If I accidentally bought lamp without turning I think I can use internal parts to get turning function from my old lamp since they work fine, only bad exterior on it. If I now code turning function off with diagbox the green blinking stops.

[GiveMeABreak]

No, that part 6206A1 is for the version without Directional lighting.....
