I have probably the same problem with my car which is ct200 premier ,plate 61., bought a year and a half ago. I’ve been told from the seller that the car had light incident on the front bumper and fully repaired, no category recorded. Anyway I have the warning light CHECK THE HEADLIGHT SYSTEM on every time when the low beam comes on !! Very annoying, I’ve been on diagnostics and the fault code which coming out is B2430- Led headlight LH and the mechanic can’t find the problem cause everything works fine !! So I’m wondering did you manage to fix it, cause the fellas at lexus service want from me £400 just tell me is the headlight ecu faulty or not, but not to repair it!!
