Omega B – VFL – X25DT – BC message – Luminous light

Hello. I’m new here and need a little help. My Omega 2.5TD BJ 99 VFL, BMW Motor, Klimatronik, 225T KM shows driving light in BC. When switching on the ignition rules the headlights from top to bottom. When it’s finished with rules comes in BC the error and it no longer regulates up when I stand in the trunk or put on the front bumper. Also, it stays where it is. But I’ve somehow not found the right thing here through some forums. I bought the Omega last year in August. Since then I’ve already had to do control chain and new head+ seals. Now I’ve found that there are no Xenon installed but halogen. The water tank for the disc washing system, however, the exits for the Xenon were blinded probably by the predecessor. Since my Omega`s had no xenon standing a bit in the dark.
