I wondered if any one had noticed a slight buzzing sound behind the interior lamp on the W202?
I asked at the dealership today and there is in fact, a small fan behind the lamp which drags air over a temperature sensor. The fan runs when the key is in the "2" position.
Mine was making a droning noise (you can notice it if you switch the fan off with the ignition on), cost of a replacement, £47!
