once When they became clogged. Would have been good preventative maintenance and saved me alot of cleanup had I done it sooner!

Also, if I remember correctly, it was packed full of mud/debris, probably from one of my off road adventures back in the day. I miss those days, I wouldn't dare try to take my 330i off the pavement.....For that matter, I wouldn't do anywhere near half the stuff I used to do in the benz with my 330......or any car for that matter....ah to be young and foolish again.
