Title: Field of Vision (FOV) headlight range problem
Post by: our_house on 28 November 2010, 20:11:36
Hi all,

I've got an "check" appear on the dashboard computer thingy. about the headlight field of vision, and the head lights have set themselves so they shine as close to the car as possible. Any ideas what I need to look at?

thanks

Personally I would start by checking the level sensor that lives either on top of the front or rear n/s wishbone behind the wheel.  It will look something like this:

Check that the arm has not come off the ball joint on the wishbone mount. ;) ;)


After that it is a case of checking the headlight motor workings.

on the passenger side wishbone there is a level sensor and on the passenger side rear wishbone there is another one. check them, probably the rod poped out or in the worse case the sensor arm fell off :(

As Lizzie says, NSF suspension height sensor.

If only one headlight is low, look at servo motor for the high one

Note, your sensor will look slightly different to that pic, but will be in same place, and with same arm that can pop off :y

It won't have the roll of insulation tape wrapped around it !!!  ::)  ::)   ;D   ;D

Great, thanks guys. I'll check that first. I'm hoping that, as both lights are low it is this and not the motor on the lights. This looks easier to get to!

My concern is this:

  Omega Owners Forum › Omega Help › Omega Electrical and Audio Help › Xenon light pulsing

which I posted the other day. If they are related i'm not sure it would be the sensor...would it???


thanks

I have obviously missed your other thread, but the error you get on the display is related to the headlight levelling system.  If you have bulbs that are going out, or go purple in colour, that is more likely the bulbs.

Indeed ;D, but that is also a new style sensor, and looks a bit different to the old ones :y

Correct TB, and with a 'new' £110 (with TC) price tag to match!! :'( :'( :'(

The worst bit I fitted it to my CDX just two months or so before it was written off! ::) ::) ::)

Hi, thankyou for that I have just been outside and its snowing, and pushed mine back on. No more check message.
A picture paints a thousand words. Hope yours is as easy to fix. What a brilliant place this is. :)

That's good news TQ! :y :y

If it comes off again, which sometimes they do, some on here have used a cable tie to make sure it doesn't happen again :D :D

Hi, I have been thinking, what if it pops off again. Sounds like a good fix to me. Thankyou for your input.  :)

a little retrofit question.. will i be able to retrofit on my facelift headlight adjusters from an 1999 omega?? they are slightly different

Hi all,

Is there definately two sensors? I can see the one at the front, and that's looks OK. I can't see the one on the back, has anyone got a photo?

Is there any way of checking these are working? all th bolts, screws etc on the front one are solid as a rock, so I can't see i'm going to get it off without breaking it.

Alternatively, is there any way of fooling the system into sticking the lights in the middle?

thanks

O course we're sure  ;). A duff sensor looks the same as a good sensor  ;) It's on the rear radius arm, towards the front, it's exactly the same sensor, just different bracket.

You need a code reader to determine exactly what has failed. Soak everything in a GOOD penetrating fluid ie Plusgas a couple of days before you start.

just fixed my omega headlight adjuster.. it was nothing wrong with it :)). two inches from the socket probably a mouse chewed on the wire and it was snapped :D. i even bought some adjusters from a breaker  :'(. check for your wires too when this happens.  ::) :y

Have checked both sensors and they both look OK, checked the wires and connections and they look good. Checked the fuses and they're OK.

Does anyone know where the other end of the wires go, so I could check them?

How do the sensers work? are they just a variable resistor? how could I check them with a multimeter?

or any other ideas?

I am in Lancing in West sussex...if anyone has a code reader???

thanks
