Per the EPC the part number is A126 528 00 85. I may have to order two myself. I have some sort of rubberized/tar type of tape in the front bracket and I always have wondered if Mercedes did something that inelegant. The back bracket was removed at some point on mine so I just copied the front bracket solution when I found a bracket. I do remember it was a pain to line it up. I think I loosened the bottom bolt too and had to jostle it around until the air cleaner lined up reasonably well. Once you tighten the various screws/bolts the air cleaner holds firm. Is the bolt/screw combination for the front bracket original? I always assumed someone lost a screw or bolt on my California wagon.
