Having problems with your 2003 Mercedes-Benz E-Class ?
Continous problem with batteries inside lights not working for the last 16 months .suddenly to day battery flat recharged it now the inside lights wont turn of at all continous electrcal faults nobody knows what causing the battery to rain .im sick to death of this car .needless to say mercedes dont want to know
I would look for a short in a wire and double check the light controls to make sure the interior lights aren't set to be on continuous. If that fails remove the light switch and see if that resolves the battery issue. If it does you know that is the problem and can replace it. Also, check the Main power line from the battery to make sure you haven't had the insulation where thin on it someplace allowing it to ground out.
