I have a problem with one of my friends SL car. When he start the car then it should be a check for 5 seconds on the instrument board ( the kombiinstrument) I mean that the light will light for 5 seconds, cause it is checking. But his SL does not do it....and I have checked the settings for it and the ARMDA setting but all seams to be right.....what can it be?

thank you
