Hello, the interior lighting of my Smart 451 ED3 doesn’t go off by itself. It can be switched on and off by a switch, and the switch is in the right position for the automatic shut-off. Nevertheless, the light still glows brightly, no matter what I do or how long I wait. A manual inspection of the lid lamp did not reveal any obvious errors. I suspect the SAM does not implement the automatic shut-off for whatever reason. Can it be due, for example, to a faulty door contact? The central locking works without any problems. Thanks for every tip that helps me to circle and fix the error source more accurately.
