Hi, I have Skoda superb 2010 with twin back door, for the last month I am getting faulty bulb signal in the dash and message-check rear fog light… but interestingly that actually right fog light is affected, but bulb is ok. Some times when I open and close back door fog light comes back on, but not for long. Does anyone have an Idea what could be wrong; probably there is some switch in the closing mechanism in back door or something else?

sounds like a dodgey wiring connections or is the bulb holder rusting? try cleaning it up with some sand paper and is your car still under warranty with it only bein a year or so old? take it back to the dealership you got it from and get it sorted under you warranty

Hi and welcome aboard.
