Re: Adjust Xenon lamps???
Don't know if this is any use? My partner has a 147 with none levelling lights (she thinks) and was complaining about not being able to see where she was going at night. I adjusted the beams in the following way: -
Parked car in front of a brick wall at night, about three foot back, with the dipped beams on.The driver's manual beam height adjuster set to the middle position. Noted the height of the beams along the brick line (this gave me a point of reference) and by turning a white plastic allen screw at the rear of the headlamp unit, managed to lift the beams (1/4 - 1/3 the thickness of a brick!). A quick test drive confirmed the results and further adjustment was necessary.So it was back to the brick wall for more tweeks. Now it is right. I think I used a 6mm allen key. The assembly doesn't look too strong, so care is needed!
So if your lamps look anything like the 147 at the rear, that's how I fixed it. Anyway, the brick wall trick is good for any car!
