there is only 1 leveling sensor for xenons, and it is fitted on front subframe.
you can get to it by lifting your car, removing under engine cover,find steering rack, and in the middle of steering rack, just behind it, is leveling sensor you are looking for. it costs 40 eur new at any renault dealer.
I've fitted new one on my car 2 days ago.
@all.....please don't post wrong information.
