Scirocco Central

This is an odd one! Firstly the auto headlamp function stopped working, I guess it’s the sensor at fault but have been too busy to sort it. Then I get a bulb warning on the dash telling me the front near side turn signal is not working(which it wasn’t). The fault would come and go , some days it’s working normal, other days the same warning light and turn signal not working. Then today, the fault has switched itself to the front offside turn signal and the near side is working fine. I’ve yet to check bulbs and earth connections, but wondered if anyone else has experienced this? I’m wondering if it could be a problem in the central control unit
