Xenon levelling won't work

[omegafin]

Truck backed and broke my Omega 



Luckily insurace covered all the damages but in MOT they found out that Xenon levelling is not working both are showing far too low ....

What would be the fault is any fuses involved or is control unit or sensors damaged in crash ?
should cid give some error message for xenon ?

There are level sensors on the front & rear suspension, in the UK they are on OUR passenger side, but would assume that they remain on the left for your left hand drive car. A common fault is that the arm for the front sensor comes off the sensor, check that's in place. I'd also check that when they fitted your new headlamp they manually adjusted it correctly before the electrics took over for the self level ...... they might have also adjusted your driver's side to suit the other side that they adjusted incorrectly

I have thought that cid displaly gives warning if levelling is not correct or is not working  ?

It does if it sees a fault. But the headlamps need to be correctly set manually in the first place ....... the CID can't actually see where the headlamps are pointing to

I is confused, did the truck reverse or did he brake?

Also check your 'new' lights haven't come from an Elite as they sit higher so could need manually setting up.

Truck reversed  ,  I was waiting stopped in the back.

Only right side lamp is new it was ordered from Germany by repairer....

So Elite-lamp is excatly same ( same part number ) but it is just adjusted diffrerently ??

[omegafin]

Repairer called that he won't find the fault and
His universal code reader won't find hid option. Car should check by dealer....

I have oc tester how much can it or tec do
Can i steer/test motors and sensors . Or does it just chek that hid control unit replies?

Control unit gets power from the fuses f22 and f15 could it be that one is just blown in crash but i dint find any light fault but rear fog lights are not working...

For a replacement light, adjust the aim to the same height as the other, manually.

Diags machines can not set the height.

both are in same level.

can tech2 test motors and sensors and contror unit or is it more to change new parts until it works ?

If there's a fault on the HID system then Tech II can identify the problem, it can also cycle your head lights up & down.

Both sensors are stuck in one position, is there any chance to repair them as new one costs about 250 euros !!?

Remove completely, spray liberally with plusgas, try and ease free. The little ball in the socket is what seems to get full of gunge and sticks. Once free I put vaseline in the "cup" on the old 2.5 .. seemed to work ... luckily not had the problem on the 3.2 ..

Two things.

1. If the lamp unit is new the adjusters should be free.

2. If the lamps won't adjust up, then the front panel might have been pushed back...Are the radiator/slam panel and aux belt all parallel you'll need to remove the plastic panel from above the radiator to check this

I'm starting to get a tad confused now .. so lets have a recap ...

Sensors - these are on the suspension arms UNDER the car....

Actuator Arms - these are inside the lights and are know to break as quite brittle, aluminium ones are availabale and can be retrofitted

Lights themselves - As Ex Taxi Al has just posted ......

all 3 bits need to be correctly adjusted and working if the lights are to work correctly ......
