Voltage Regulator faulty
Wiring and/or connections faulty
Possible Solutions
Check / Replace Alternator
Check / Replace Voltage Regulator
Check wiring and connections
Check the fuse box that is in the battery tray, it might be burnt, the fuse or the complete plastic box (pretty common failure on Sharan because it carries so much electrical load). If so, change the complete fuse box, it is not too expensive fix if this is the cause.
Special Notes
When found on the BEW engine, check MVB 16, Field 1. In most cases values will be between 15% to 30% at idle. 0% could indicate a failed or incorrect alternator.
