    As far as the self-levelling for the lights goes, check on front and rear suspension for little sensors with a position arm on... the arm is known to pop off and cause an error message - typically something like 'low beam out of range' or similar.

    If it's ex-police you'll prob find your air-con doesnt work either..lol .... my old Vec B Sri V6 was ex-police too, they removed the air-con/changed wiring for sirens, independant flashing lights, radio's etc... i had to have an auto-elec to mine to sort it, he offered to leave siren there for a laugh but i decided against it..lol

    If I remember correctly the info to display and steering control is powered by a red/white wire on the back of the display unit. I discovered this when attempting to get song titles when using aftermarket stereo.
