The nose weight in the book is listed at 110Kg for this car which is probably about normal for most cars of this size. You suggest it may be the wrong spring are you thinking that it may have the self leveling spring or the other way round.
Re the dealer not much help there basically they are saying were not experts in towing so cant comment repeating the blurb in the book about 110Kg nose weight showed them the nose weight when there and the response was it is what it is Not all helpfull.
