M44 diagnostic port cover part number? Broke the cap from the leash today. Mallard posted in 05/2008: New part number: 12 52 1 724 690 Old part number: 12 52 1 711 220 690 seems to be for the M42 engine, according to realoem & bmwfans. Does anyone know the correct number for the M44, or have an intact cap/leash for sale? Thanks in advance! |
