In my 2005 Jetta. A search says that number is linked to Helsa Automotive which was bought by Mann. And does the date mean it was made in 2007? Cant be from 2016 as I got the car in 2012. The car has been sitting since then and the filter is like new, I blew it out with air and there was no dust or dirt in it. Any reason it can't be reused?
