It can trace a LOS through the gap as stated by Randy per B9.1.
If a unit during its MPh moved behind that wall and the Defenders LOS is through the gap, then the moving unit does not get Wall TEM.
If a unit is located behind a wall and fired on during the DFPH (i.e. Final Fire), it does get Wall TEM even though LOS goes through the gap in the wall. Still, LOS is not blocked if it goes through the gap when Final Fire is targetting units behind the Wall hex even though unit in the Wall hex do get Wall TEM.

Almost correct but the gap in the Wall/Hedge exists during the
RtPh and
APh as well. As
B9.3 points out "
If the LOS crosses the wall/hedge hexside through a road/gapJ11 depiction (such as 6W9-X9) the wall/hedge TEM can only apply if the target is a non-moving unit. " Since during both RtPh and APh units are considered moving (
B10.4 ...Broken units may neither attack in any way nor
move except to rout during the RtPh;
4.7 ADVANCE PHASE: Infantry units which are neither broken, pinned, TI, nor marked with a CC counter may use the APh to move one hex... &
3.7 ADVANCE PHASE (APh): The ATTACKER may move any of his Infantry units capable of movement...), the gap can have some impact in both of these phases as well.
