Hi there.

I had my 2007 BMW 116i in for repairs. When I got it back I still had this rattling noise. They said they could not find what it was.
I tried to figure out myself why it sounds the way it does. I pulled out my MAF sensor and the rattle dissapeared for a while. I then thought of the VANOS. So to exclued wich Vanos it was (Exhaust or intake) I disconnected the pins on the solenoids. When I pulled out the lower one (exhaust?) the rattle stopped.

Am I on the right track or could it be DISA if I have one?

Sorry if my english is bad.

Best regards.
