That particular statement is also wrong. For this particular setup you can also buy the correct cable (making sure to not get the one that inverts some pins!!!) for cheaper. Mine was around 15$.

Parts and labor combined that would be a 4000-5000 eurobuck job. A Nissan importer tried to weasel out of a warranty replacement on a friend's X-Trail so they first offered to completely refund options that had become unusable.

The car was full of issues and probably spent more time in the shop than on the road. Nissan finally had to buy it back after service techs failed to tighten the oil drain cap after an engine overhaul.
