That would be good if you could see...
My 06 Pre lci 330i did it, my 09Lci 335i does it and several courtesy cars have done it too.
Just sit stationary with your foot on the brake and put your wipers on intermittent.
Each start of the 'wipe' of the wipers is accomanied by a 'thunk' you can feel (not hear) though the pedal.
Some have suggested its the brake drying 'pulse' being applied (a feature of 6 cylinder models, and maybe all models more recently) but I don't know, and yours is a 330.
