Code moteur p0362 207 1.4l HDI

When I move the front passenger seat to front and back (in order of people to get inside the back seats of the car since its a cabrio) it sometimes gives this error, than error disappears itself. Now it doesn’t disappear. I don’t know what to do, tried to push the cables under the seat but didn’t work. A place said we need to remove the seat completely, we need parts, it will take time and cost much (without looking the issue).
