Looking for a replacement 4/5 switch memory control unit for a 2000 A8 that fits in the door panel. I think it is the same for most models of V8 and A8 from at least 94-02. It is the 1-2-3-4 with memory save button in the middle. I'd like the whole block. The A8 part # is 893 959 769 or 4D0 959 769. Color is black or charcoal. Tx Roland
