The leaf trap is one part of the W126 design that is really poor. During the fall I will vacuum mine out once a week, if you stay on top of it, it never gets bad.
I stuck a 5/8 copper pipe in the vavuum cleaner for some reach. Combind that with the air compressor and I am able to blow/suck all the leaves out.
Wow that last sentence didn't sound right!
