Desperately need to know the part number

:wallbash:My apology if I am asking this question in the wrong place. It is my second posting & still can't find the "sticky post in the new members" but I am hoping that you forgive this. I desperately need to know the part numbers for xenon control unit & ignitor for CLK200K elegance 2003 (WDB209342) with HID factory fitted. Also if you know the Bosch OEM equivalent part number. Many thanks
