this is a bit late but i also could not find one in durban at the scrapyards.Unless you find a e90 in the yards to salvage through the scrappers have no idea what a MULF is.I just hunted through gumtree looking for guys stripping a e90 and sent them a photo of the part located in the boot.remember to check your prewirding if you have a blue or white connector,because your MULF/TCU needs to have a matching connector
