The path from the oil filter to the oil pan is not a straight line or gentle curve like engines with a dip stick. The M3 (S65) engine uses a dual sump oil pan that has front and rear separated oil sumps. The oil filter is mounted to the front of the engine. If you some how magically were able to get the plastic suction tube into the bottom of the engine you would not be able to reach the larger rear oil sump. There are two drain plugs because of the dual oil sumps.
If you get the plastic suction tube stuck in the engine your crying will last a long time,
and cost about a life time of BMW oil changes to remove.
