Hello Forengemeinde, the FIS in the Exeo shows “marking lamp defective” and I could not fix the problem with the exchange of the light bulb (light bulb worked perfectly in the other socket). As far as I know from the research, there was a service action with the exchange of the wire harness (or at least share) because of defective marking lights. However, on demand my Exeo is not affected by this because of the construction time. e Search starts, I would like to ask you whether similar problems have occurred with other vehicles from this construction period (EZ 08/2010). Make the argumentation easier for me afterwards, if I have just the only car in which this occurred 😉 Greetings, Maestoso
