Most Reported On
U1111 is an OBD-II diagnostic trouble code meaning “Function Restricted Due to Missing Message(s).” A control module is not receiving one or more CAN/data-bus messages it needs to operate, so it has deliberately restricted or disabled its own function rather than act on stale data. U1111 is a symptom code, not a root-cause code: it tells you which module went blind, and the real fault is whichever module or bus segment stopped transmitting. On a VW Tiguan with a Haldex AWD complaint, U111100 in the cluster or Haldex controller usually means the AWD controller has dropped off the bus or is not sending its status. This code is most commonly reported on 2009-2022 Volkswagen Tiguan (4Motion, SE 4Motion, SEL 4Motion, SEL Premium R-Line 4Motion), with repair costs ranging from $250 to $2,200.
