So, go ahead, I want the interior mirror in Golf 3, what I have everything, are circuit diagrams etc, what I lack is only ne gaaaaanz simple info! and that’s what I have here 2 models lie, one in grey and one in black. Now to the interesting, the gray has an ambience lighting (identical with the W8 light), the black does not! Here the part numbers: 3B0 857 511 C 1C0 (black) 3B0 857 511 J Y20 (grey, ambiente) so who knows more than I? achja, the gray is not listed at vw at least not in the proof of use, in the price list already!
