Headlamp leveling stopped working after fitting angel eyes

Is there something I'm missing?
I removed my 06 facelift headlights to install angel eyes, the power on is connected to the aux live in the ecu box as suggested in all the installation how to's, I first noticed the nearside leveler wasn't working and the offside was OK, later the same day the offside had stopped.
Now I can hear the motors trying to work when they do their check and when I use the switch on the dash (in uk) but the lights do not move.
I've had them apart again and no wires are snagged or causing them to jam. I tried with no lens covers on and they do not move.
I am at a loss to what's causing it.
Has anyone any ideas?

Logic would suggest that it is something to do with the fitment of the AE's. Which ones did you fit? I fitted Umnitza Orion 2 on my 2004 (UK Spec) facelift 330Cic about 4 years ago. They work fine and I also used the power trigger from the aux live in the ECU box. make sure that the AE cables inside the light unit are not fouling anything up, especially as it sounds as though they are "trying" to operate.

If all else fails, remove the AE's and see if the levelers start working again.

Thx for your reply, I have checked that there are no cables fouling the mechanism, the lights I used are led rings from a supplier here in the UK and work great, I have had the lights installed with the front lens cover woth the rings removed and it's the same,
I'm not 100% on how the full system works, I know they are not the adaptive lights that move when you turn corners but am wondering if their is a way of resetting the light control unit as there may be a glitch in the system as such.
I have had it where stuff doesn't work correctly after removing the battery like the windows until you clear the errors generated because of the battery removal.
I have scanned for errors for the lights and found none.
Only thing left to try is to swap some lights with another car and see what happens but everyone I know have pre facelift.

The only other thing I can think of is that the bi-xenon self levelling sensor has moved or become disconnected somehow. I have not had problem with that on my car so cannot be specific. However, try searching this or google it and you may be able to see where it is located and then see if it has become disconnected or dislodged somehow when you removed your headlights. Clearly there is a connection between it and the light units. Good luck!

Sorry, thought I said they were halogen, mine done have the auto leveling system. I've Googled Google to death lol... the wiring seems fine and I can hear the motors.
The facelift motors don't connect the same way as the pre facelift and cannot be removed like the pre facelift.
Thanks for you suggestions though as it's your and others help that I am seeking as google isn't giving any definitive answers.

If you hear the motors moving, but the lights aren't moving, logic dictates that the motors are physically disconnected inside, or something is jamming them.

ie had a good look and cant see anything that can jam it, they are not the same setup as the pre facelift that have the ball that can become dislodged, there is nothing that can separate from what i see, only thing i can do is strip them down totally and see what the motors do with them removed.

**Update**
Ive had them apart and stripped down as far as i could which is basically cracking open the silicone sealant its bonded with and removing the front headlight cover, the internals are pretty much fixed solid and are non removable, ive had a snake camera poking around and there is nothing loose to jam anything which leads me back to maybe its a communication thing between the motor and the light control unit (maybe?) is there a away to reset the lcu? there are no errors showing with inpa

Have you tried totally disconnecting the electrical power source to the AE's? IE, put the wiring back as it was before you fitted them. It may be something power/ voltage related.

Yup tried that, also disconneted the earth to the battery for 1 1/2 hours to try and reset the electrics on the car. The power wire is just going to an auxillary live on position 2 on the key from the ecu box, it's the same one that's recommended in all the how to's, only things left to try is either a different lcu or different headlights that are known to be working.
Thanks again for your inputs, the whole thing seems strange the way it occurred.
