We just got a second w210 last week (1997 e320). A strange noise has started in the overhead console just to the right of the sunroof swich. It is coming out of two small (1 cm) slots that look like vents. It sounds like radio static or a tiny fan with a bad bearing. The sound starts when the ignition is turned on and stops about 10 seconds after key is turned off.
Using any/all the overhead console lighting or sunroof switches has no effect.
What do they have hiding in there? Anyone have a clue?
