Just want to put my mind at rest on this question.
The rear S/L suspenion has no effect what so ever on the level positioning of HID lights ?
-
Level positioning of HIDs controlled by sensors on wishbones, which signal the motors back of headlights ;)
-
Simple answer, no. They are completely different and unrelated systems.
However if the back sits low, or high, due to sl suspension position, then the lights will adjust. But then that's that case regardless of sl fitted or not. But sl shouldn't allow the rear ride height to vary anyway.
-
Correct :y it has its own sensors front and rear.
Although the Elite system might talk to the HID level control :-\
-
Reason I ask is on every start up I get "headlight field warning" appear on the display although clears when press required button.
Got me thinking as I have done all the possible tests for headlight aim without Tech 11....both back/front sensor arms are connected ..have been removed/greased and refitted.Light servo motors were both replaced with working spares when fitted ali adjusters few weeks ago so unsure whee to look now.
Car has S/L suspension being an Elite but shocks were replaced at somepoint with standard and air pipes disconnected so got me thinking if this could be related in some way
-
Nah, head light levelling has a fault. Wiring sound? Iirc Kev had a wiring issue on his rear sensor.
-
Make sure the car is level and remove the link rod from the sensor on the offside rear suspension arm. That should stop the ecu from receiving odd signals from the self leveling suspension side of things :-\
-
Will try that.
Remove the S/L sensor on rear O/S arm so in effect making the car think all is level..then see what happens with the headlight warning .
If it dosen,t come on then maybe some comms between S/L and headlights then ?
-
when i fitted those angel lye headlights in my miggy---kept getting -field vision high--on my display----took it to mares mot center and he set up headlight beams----display went off---not come back since :y :y

I am not sure of this Chris. As I have posted several times on this issue - I used to get the level warning quite regularly and just cleared it and carried on. Kevin Wood came round maybe 3 or 4 years ago with Tech 2 and proved that nothing was wrong and light system - all working fine. So I just ignored it and warning message never seen again for a couple of years until....the other day when it appeared once only - and not again since. I am thinking that moisture maybe affecting fusebox or wiring but is it worth messing with?
-
Had you just driven through a puddle?
-
If the system is working correctly, the error message is never seen. There for, the system is seeing a fault. Just is. Finding it however...
-
Car has been standing for some time now and even when I collected it a few months ago .(in the dry) the fault message still appeared.
If the fault message is appearing does that mean the headlight levelling isn,t working..I mean the headlights are not adjusted correctly and potentially will fail a test
-
The motors "could" be aiming the lights down, and the headlights adjusted to the correct position. Potentially.
Or they could be fine and the fault is a momentary kwirk.
Not Sure on the mot test re the error message.
Engine off, ignition on, lights on. Turn the ignition off then on again, do the lights move up and down? Its a hit and miss test though.
I think you'll struggle without tech 2 tbh :(
-
Will have a proper look at the potential light movement against house wall as suggested,but with weather may not be till Saturday evening now.
If not will need to arrange a chat with Tech 2
-
Maybe see what Kev says in the mean time.
-
Any recent excursion through standing water might have dislodged the rear sensor... if the sensors are past their best and have some play where the arm attaches to the sensor, then they might send duff messages to the ecu :y
-
It might. But if dislodged I'm sure you'd have the warning popping up every few minutes, no? My memory is the warning is a persistent bugger, going by the issues I had with a front sensor that kept popping off due to seized ball joints.
It's always worth examination to see that the sensor arm is firmly pressed into its socket and that the ball joints on the little link rods are not rusty and seized.
But I had assumed you'd been down that road already? And are now clutching at straws?
-
Yes,straws are very much being clutched.
Both sensors have been fully removed,cleaned and fully inspected.Very little play on arm and ball joint sits tight and moves freely,although as car has been sat on driveway for several weeks now I had assumed that the level sensors only came into play when the car was moving so as to keep the headlights level.
I will again remove each arm and see what effect it has on the light position ,as I assume when removed if you then move the arm the light servos should operate and cause both lights to move sligthly
-
That's the theory :y assistant very much required...
