yeah this car is always been serviced/maintained at BMW which is good so is always used genuine parts, but things seem to be replaced when they break rather than preventative maintence. the fuel filter for example has BMW stamp on it, but it might be the original who knows. i must check the date stamp on it. I use parts sourced by third parties direct from bosch/alto/etc rather than via the dealership so same parts but just dont have the 150% markup and the BMW stamp and part number on the side of it. made by the exact same people though.
