Something we can do here is to add a restriction, which will prevent through-traffic. All good navigation engines can honour this restriction.  That would solve your problem.

@ValMar6920: perhaps you live in this area.  Can you confirm there is a C3 road sign with something that says "Excepté circulation locale"?  We have old pictures that show it when entering from N94 (Rue de Dinant). But we do not know if there is the same sign when entering from the other side.  If there is one, is it near the crossing with "La Venelle" or after the last houses?

(If you could take one or two pictures showing the roadsigns and their surroundings and post them here, that would be just perfect.)
