NCT help - levelling device?

welshireland · 23-04-2019 12:43pm #1

Hello,

I have a 2014 Golf GTD that has failed the test today on

Head light Condition Leveling Device Not operating
&
Head light Condition Intensity Not acceptable Offside front

Can anyone advise what this leveling device is ? It must be a motor or a sensor I would imagine ? when i turn on the car i get a warning that the day time running light does not work on that side but it does physically work

thanks a million ,
Michael

What they do is on start up is go up and down and settle at correct level.

It is either caput or a wiring issue.

Could it be the rear sensor for the xenons.
look for a gadget in the rear wheel arches thats broken .

Do you have aftermarket headlights, or factory? Sounds like your headlights are misaligned. So you get flashed a lot?

welshireland · 23-04-2019 12:58pm

So this issue caused the intensity issue also ?

if its Caput what do you need to replace ?

I will turn the car on and off and see do they go up and down .
I am a bit of a hobby mechanic but electronics would be my weak point.

these are Factory headlights on the Golf GTD, NCT advised that the near side rear is pointing to the floor ad the levelling device is not working at all.

thanks

A lot of cars now have a levelling system, dial or knob, for the driver to adjust the aim of the lights if fully laden. It sounds like the adjusting mechanism for the one side is in its default failsafe mode ( pointing down ) Could be many reasons from faulty wiring, blown fuse or jammed mechanism.
Sorry can't help anymore than that but a good poke around the headlamp unit by a reasonable VW mechanic might point out more.

Found this for you might help

Does your car have factory fitted xenon headlights? I think most GTD models do so factory fitted xenon headlights have an automatic self leveling motorized system as required by EU regulation. It's possible that one of them is no longer working.

When you turn the car on at night, do the headlights go through an alignment process ? i'e do the beams move up and down (possible left and right too) before settling on a postion ?

If you have factory xenons then you will have 1 or possibly more level sensors - usually on the rear passenger side suspension and front passenger side suspension. This is so the car knows how high the front is in relation to the rear and knows what level to adjust the lights too. If the sensor was damaged then both would be either pointing too high or two low and you wouldn't get the allignemnt process on start up.

The sensors themsleves are around 80-120e and easy to replace once the car is off the ground.The don't always physically break sometimes the sensor just stops working.

5 minutes with VCDS will diagnose what's going on, where are you based ?

Yes but how do i diagnose the problem to fix it. Plugging it in is not giving a specific fault i.e a sensor gone ect

See the post from tossy after mine.

It does sound like a range control sensor is bunched.

It's a little pivot arm near the rear drop link on the passenger side rear. I think the arm on them is green, so it should stand out if you stick you're head in.

They are prone to failure on most VW stuff so its be a good place to start with this one. If the sensor is knackered the lamp could be pointing at the sky or down to the ground and that's why you've gotten the lamp intensity fail too.

Would that not affect both sides TFBoi ? Seems it's just the Driver's-side Light that is 'off'.

edit: it does sound more like the self-levelling motor on just the Driver's side that's giving trouble....as suggested by Bazz.

edit: post #1 says offside....post#5 says nearside. Either way it sounds more like a Light located issue rather than one of the Front/Rear Sensors. BTW what did you "plug" it into to check for error codes OP ?

It can, and most probably will. They diagnosis can be so good on some sensors that it can even tell you which wire of three is damaged, if it was a wiring issue for example.

Give the lever arm a quick check, after that the fastest things is a VCDS check
