    Might be a little difficult James but here goes.

    The number 8K0941004 was dropped on 01/11/2007 and replaced with a combination of 8K0941030 and 8K0941454.

    So information on the 8K0941004 is scarce.

    Silly question but are you sure it has LED's?

    LED control unit for 8K0941030 C or D is 8K0907472

    hi stu ye definantly led, i have been down to audi and they kindly with a twist of the arm and lots of nagging gave me the part numbers so i now have them on order, they did how ever scare me a little by saying they would never do this upgrade as it means alot of electrical changes to the cars electronic units < i was a little lost at this point with the electrical jarging > i was just wondering if anyone had done this upgrade them selves and come across any problems

    I just went through this upgrade with a shop here in Houston, they need to do the coding on your audi in order for the Led to work, I am not sure if you already had this done or not.
