Has any one had a problem with thier headlights mine have started going up and down really quick I thought I have read on CL before that the sensor for the auto levelling is on the rear axel ? I'm guessing that as both light are doing it it must becoming from that sensor on the axel or ecu does anyone know the exsact position of the sensor on the axel ? And the position of the ECU for the auto levelling lights ? It's a 2006 GS430 any ideas guys thanks James
