Took my 08 e92 M3 in for a brake fluid flush on Saturday. When the SA read the key, the car told him I also needed differential fluid, oil filter and spark plugs. The he read the mileage and said oh you only need the brake flush cause your car is low miles. He said the other stuff is not required until 37k miles. My car has 20k miles and is low miles. Any thoughts on this? My inclination is to have them do what the key says is required. Especially since the factory warranty runs out in three months. I do have CPO and extended warranty until 7/ 2014.
