I have a 2001 C320 Sport. When I start the car after it has been stopped for a while (i.e., not EVERY time I start it), I get about four or five loud mechanical clicks coming from under the dash. I can put my hands on the dash and feel the click from around the steering column/ignition switch. It stops after four of five clicks. I see no other probelms with any other functions. I haven't taken it in yet for service, but will soon and I wanted to see if anyone has any ideas of what it might be.
Thanks.
