What they havent told you is that it is illegal to fit a different type of globe into a reflector designed for HID, so fitting the self levelling thing is the only correct thing to do... Just dont tell them that theyve asked you to do something illegal or theyll get upset ..
i'd just take out the HID bulb and use the fog beam instead. There is no reason why you cant use the fog beam as a low beam. According to ADR's, the reflector is within the correct height tolerance from the ground, it is within the right distance from the cars width, and is the correct wattage, it only needs the beam height set...
then once the car is signed off, go home and put the HID bulbs back in. happy days
