EURO HID - Lower Suspensions

**flypig** · 18-09-2006 05:46 PM

Hi everyone,

I just put a set of coilovers on my 04 euro lux. front with 60mm & rear with 40 mm lower. Only notice last night that my HID (low beam) doesnt light up the distance as used to be. I thought they are auto leveling, but it seems very hard to drive at night now because the low beam just heading the ground.

Can they adjust manually?

Thanks

I lowered my o6 and it snapped an arm to a sensor on the passenger side front. If you look at the front side of the wheel and check at the bottom of the shocker It should be connected to the shocker and run to the body of the car. it is about 15cm long and i think it controls the level of the lights. i haven't fixed mine as its not covered by warranty even thought he car was 4 weeks old.

due to being lowered. But im pretty sure it is the control for the lights. See how you go hope it helps. But my lights have been all good. I took the arm completely off it was making a ticking noise over bumps.

I am pretty sure u can adjust the lights manually by using the screws which are located in the engine bay. Just drive the car back a bit from a wall and mark out an aiming marker with some tape... Distance of the markers should be in te Euro handbook as it is a regualr maintainance thing

note that the height of the beam is relative to the height of the headlight(i.e. aiming standards for hid lights basically say that you measure the height of the headlight, then aim them a certain amount below that), so when you lower the car, you are going to lose some distance in the amount of illumination your lights are capable of maintaining.

I think you are correct. The only thing is if they are auto adjust there has to be something that has caused the lights to dip excessively.

I just checked the Euro manual book - page 131. It says that cars with HID is equipped with an Automatic Headlight Adjusting system that senses changes in the vehicle posture due to riding and loading conditions of the passangers & their luggage and adjusts the verticle angle of the headlights (low beam) auotmatically.

Can anyone sure about that little sensor was bolt on the bottom of the passengers side of the shock was the actual sensor for the HID?

Thanks

most hid autoleveling systems use a sensor at all 4 corners, or at least front and back, to determine how the car is sitting relative to the ground, for accomidating for not only load, but inclines and declines in the road, etc

There is 2 sensors one at the front and one at the back.

Checked the workshop manual and they are located on the left front and rear suspension assemblies between bottom wishbones and the body by the looks of it...

Had a look under the bonnet and on the top of each light right next to the 1/4 pannels there is a covered hole which has U-->D... take the cover off and you should still be able to adjust it manually using a screwdriver and a target board. You lights just wont dip when loaded which can still be a problem??

PDF of aiming procedure (this is american ours will be opposite)

The only question i raise is.

If it is lowered now and the light has adjusted. Could you do any damage to the adjuster as the light adjustment has moved to compensate for the lowering??

Just a question.

I dont think so - the adjuster would have an inbuilt feedback loop so the motors knew where they were relative to the road position and the travel left in the adjustment range. They also have to stop adjusting at a point lol

Adjusting it in theory should just decrease the range in which the lights aim up when going down hill (this is assuming that the lights are now pointing more toward the road since the viewable distance has decreased)

On a related note - I was looking at getting some tein ss coilovers and noticed that the jap catalogue states that all tein coilovers are not for auto adjustment lighting... can anyone prove or disprove this?? Do they not have sensor mounting points??
