does it matter what my first language is, my sex, disabled, religion? i have had my 146 since it was 1year old. i can only give you my experience. if auqualis takes the inner pannel of the door and puts his fingers in to feel the action of the door handle to the lock he may feel there is a miss. mine was completely missing. would not catch the engament on the lock. once replaced it worked fine. some things on alfas are really not that complicated! less of the i am o so inteligent!!
